Planning tools
Guyana
Georgetown · Guyana
Demerara-Mahaica · ~6.8°N · city access hub
Coastal Georgetown sits under humid Atlantic trade winds, so transparency often improves after evening showers clear. Near-equatorial nights keep the Milky Way core high when the moon is down.
Bartica · Guyana
Cuyuni-Mazaruni · dark-sky gateway · darker Bortle skies
Bartica is the classic jump-off toward darker Essequibo and interior skies once you leave coastal light domes. Check cloud decks and dew point before a night drive upriver.
Lethem · Guyana
Rupununi · ~3.4°N · darker Bortle skies
Rupununi savannah around Lethem ranks among Guyana’s darkest accessible horizons. Dry-season nights reward wide-field Milky Way and satellite watching when dust settles.
Mahdia · Guyana
Potaro-Siparuni · interior · darker Bortle skies
Interior Guyana near Mahdia stays far from coastal light pollution when weather cooperates. Confirm transparency and moon timing before committing to a forest-edge session.
Mabaruma · Guyana
Barima-Waini · north-west · darker Bortle skies
North-west Guyana around Mabaruma is a dark-sky candidate with sparse settlement glow. Pair weather layers with a moonless dark-sky window for the best hours.
Caribbean
Paramaribo · Suriname
Suriname coast · ~5.9°N · city access hub
Paramaribo shares Guyana’s near-equatorial sky clock but with a denser coastal light dome along the Suriname River. Inland clearings after tropical showers can open brief deep-sky windows.
Port of Spain · Trinidad and Tobago
Trinidad · ~10.7°N · city access hub
Port of Spain’s urban glow pushes serious observing toward the Northern Range or Tobago’s quieter coasts. Dry-season nights still deliver bright ISS passes over the Gulf of Paria.
Kingston · Jamaica
Jamaica · ~18.0°N · city access hub
Kingston’s basin traps city light, so Blue Mountains ridgelines are the usual escape for darker skies. Tropical convection means the clearest transparency often follows a late-day storm.
Caracas · Venezuela
Capital District · ~10.5°N · city access hub
Caracas sits in a mountain valley where orographic cloud often hugs the hills while coastal Vargas stays clearer. Elevation helps transparency when trade-wind haze stays below the ridge.
Havana · Cuba
La Habana · ~23.1°N · city access hub
Havana’s humid subtropical nights trade bright city glow for quick-clearing showers. Drive east toward darker Matanzas and Zapata shores when the forecast shows mid-level cloud dropping.
Santo Domingo · Dominican Republic
Ozama · ~18.5°N · city access hub
Santo Domingo faces Atlantic moisture and afternoon thunderstorms that can leave crystal evenings. Interior Cordillera dark sites beat coastal light for deep-sky once humidity falls.
Bridgetown · Barbados
St. Michael · ~13.1°N · city access hub
Barbados offers open Atlantic horizons with steady trade winds that keep dew moving. East-coast dark pockets away from Bridgetown glow reward short island drives on moonless nights.
Latin America
Bogotá · Colombia
Andes · ~4.7°N · city access hub
High-altitude Bogotá nights cool quickly, but Andean cloud and humidity still decide transparency. Near-equatorial latitude keeps the galactic centre reachable for months when the altiplano clears.
Quito · Ecuador
Andes · ~0.2°S · city access hub
Quito’s near-zero latitude puts both celestial poles low and the Milky Way nearly overhead in season. Thin Andean air helps when afternoon convection collapses after sunset.
Lima · Peru
Pacific coast · ~12.0°S · city access hub
Lima’s coastal garúa cloud often blankets the city for weeks, so serious observers watch the Andean foothills inland. When the marine layer retreats, southern winter Milky Way nights open fast.
Santiago · Chile
Central Chile · ~33.4°S · city access hub
Santiago sits under a bright valley light dome, yet nearby Andes foothills feed world-class Chilean dark-sky culture. Winter nights bring Magellanic Clouds and a towering southern Milky Way.
La Serena · Chile
Coquimbo · astronomy coast · darker Bortle skies
La Serena anchors Chile’s Coquimbo astronomy corridor near Cerro Tololo and La Silla heritage skies. Coastal fog battles clear highland air — pick elevation carefully on any given night.
Buenos Aires · Argentina
Río de la Plata · ~34.6°S · city access hub
Buenos Aires light pollution is intense, so dark-sky drives toward the pampas matter for deep-sky work. Southern winters still put the Magellanic Clouds and Scorpius high for coastal observers.
São Paulo · Brazil
Southeast Brazil · ~23.6°S · city access hub
São Paulo’s megacity glow pushes astronomy toward Serra da Mantiqueira and coastal ranges. Humid subtropical nights reward patience — post-frontal dry air is when faint structure appears.
Mexico City · Mexico
Valley of Mexico · ~19.4°N · city access hub
Mexico City’s altitude helps seeing, but valley smog and light drown faint targets from the centre. Clear winter nights over nearby volcanoes open rich tropical Milky Way views.
Rio de Janeiro · Brazil
Guanabara · ~22.9°S · city access hub
Rio’s coastal mountains create microclimates — one bay cloudy while the other clears. Southern winter brings a bright galactic core over darker Serra sites west of the metro glow.
Cusco · Peru
Andes · ~13.5°S · ~3400 m · darker Bortle skies
High Andean air above Cusco thins haze and sharpens southern deep-sky targets. Altitude cold and thin oxygen matter as much as cloud decks for long sessions near the Sacred Valley.
Africa
Nairobi · Kenya
East Africa · ~1.3°S · city access hub
Near-equatorial Nairobi sits high enough that nights cool quickly after sunset, improving seeing when dust is low. City glow is strong, but highland escapes reveal both hemispheres’ summer Milky Way arcs.
Lagos · Nigeria
Gulf of Guinea · ~6.5°N · city access hub
Lagos humidity and marine haze often mute faint detail even when the forecast says clear. Equatorial nights still reward bright planets and ISS passes over the lagoon when Harmattan dust is absent.
Accra · Ghana
Gulf of Guinea · ~5.6°N · city access hub
Accra’s coastal light and sea mist favor bright-sky targets over faint nebulae from downtown. Dry-season Harmattan nights inland open longer dark windows for equatorial Milky Way photography.
Addis Ababa · Ethiopia
Ethiopian Highlands · ~9.0°N · city access hub
Addis Ababa’s high elevation thins the air and can deliver sharp stellar images when the rainy season breaks. Urban glow is rising, so darker plateaus outside the capital unlock deeper southern sky views.
Cape Town · South Africa
Western Cape · ~33.9°S · city access hub
Cape Town faces true southern skies: Magellanic Clouds, the Coal Sack, and a winter Milky Way that climbs high over Table Mountain. Atlantic fronts clear fast but return with equal speed.
Windhoek · Namibia
Khomas · ~22.6°S · darker Bortle skies
Windhoek sits on the edge of Namibia’s legendary dark-sky highland and desert corridors. Dry air and sparse light pollution make it a southern-hemisphere deep-sky stronghold when dust storms stay away.
Dar es Salaam · Tanzania
Indian Ocean coast · ~6.8°S · city access hub
Dar es Salaam’s coastal humidity fights inland Morogoro clarity, yet equatorial southern skies put Magellanic Clouds and the galactic core high when the monsoon lulls. Plan around Indian Ocean moisture surges.
Kampala · Uganda
Lake Victoria · ~0.3°N · city access hub
Kampala sits almost on the equator beside Lake Victoria’s lake-effect cloud. Clear gaps open both celestial hemispheres at once — a rare planning advantage when mist lifts after midnight.
Johannesburg · South Africa
Highveld · ~26.2°S · city access hub
Johannesburg’s Highveld altitude delivers thin air and crisp winter nights when dust settles. City light pushes serious imaging toward Magaliesberg and Karoo-direction escapes.
Marrakesh · Morocco
Haouz · ~31.6°N · city access hub
Marrakesh sits under Sahara-edge skies where dust and heat haze compete with superb desert transparency. Atlas foothill sites often outclass the medina glow after a cool northerly.
North America
Tucson · United States
Arizona · dark-sky city · darker Bortle skies
Tucson pioneered municipal dark-sky lighting and sits beside world-famous Sonoran observing sites. Dry desert air rewards summer monsoon gaps and long winter galaxy season nights.
Flagstaff · United States
Arizona · first International Dark Sky City · darker Bortle skies
Flagstaff is the original International Dark Sky City, with high-elevation pine forests and Lowell Observatory heritage. Cold, dry winters deliver some of the Southwest’s steadiest transparency.
Hilo · United States
Hawaiʻi Island · windward · darker Bortle skies
Hilo’s windward rain often yields to clearer Mauna Kea and saddle-road elevations just inland. Near-tropical latitude keeps both northern and southern deep-sky targets in play year-round.
Los Angeles · United States
Southern California · ~34.1°N · city access hub
Los Angeles light pollution is extreme, so Mount Wilson, Angeles Crest, and desert escapes define real sessions. Santa Ana winds can produce rare crystal nights over the basin.
New York · United States
Northeast · ~40.7°N · city access hub
New York’s skyglow limits most deep-sky work to bright satellites, planets, and lunar detail from the boroughs. Cold high-pressure winter nights are when upstate and Long Island dark sites shine.
Denver · United States
Colorado Front Range · ~39.7°N · city access hub
Denver’s mile-high air thins turbulence, but Front Range light and upslope cloud still matter. A short drive into the Rockies unlocks darker summer Milky Way and winter galaxy fields.
Vancouver · Canada
Pacific Northwest · ~49.3°N · city access hub
Vancouver’s marine layer and winter rain dominate, so clear arctic-outflow nights are gold. Summer twilight is long this far north — dark windows shrink around the solstice.
Chicago · United States
Great Lakes · ~41.9°N · city access hub
Chicago winters can be brilliantly transparent after a dry cold front, while lake-effect cloud frustrates spring and fall. Light pollution pushes dark-sky trips toward rural Illinois and Wisconsin.
Miami · United States
South Florida · ~25.8°N · city access hub
Miami’s subtropical moisture and city glow make Everglades and Keys horizons the real observing cards. Dry-season cold fronts briefly unlock sharp tropical nights over the Atlantic.
Europe
London · United Kingdom
England · ~51.5°N · city access hub
London’s maritime climate means cloud is the main enemy more than dew alone. High northern latitude stretches summer twilight, so deep darkness is a winter and autumn prize.
Paris · France
Île-de-France · ~48.9°N · city access hub
Paris light pollution is severe, pushing observers toward Île-de-France countryside and Champagne dark pockets. Anticyclonic winter nights bring the longest transparent windows of the year.
Berlin · Germany
Brandenburg · ~52.5°N · city access hub
Berlin winters offer long nights and occasional crystal continental air after Siberian highs. City glow is strong, but Brandenburg lakes and forests remain popular dark-sky escapes.
Madrid · Spain
Central Spain · ~40.4°N · city access hub
Madrid’s altitude and dry meseta climate favour sharp stellar images when pollution haze drops. Sierra de Guadarrama and darker Castilla sites open rich summer Milky Way sessions.
Rome · Italy
Lazio · ~41.9°N · city access hub
Rome’s historic light dome limits faint targets inside the GRA ring, so Appennine foothills are the usual remedy. Mediterranean winters bring clearer transparency between Atlantic storm tracks.
Amsterdam · Netherlands
North Holland · ~52.4°N · city access hub
Amsterdam’s maritime climate means frequent low cloud, yet North Sea clear-outs can be sudden. High-latitude summers barely get astronomical night — winter is the serious season.
Athens · Greece
Attica · ~38.0°N · city access hub
Athens combines Mediterranean summer haze with superb autumn and spring transparency after meltemi winds. Island and mountain escapes outclass the Attica light bowl for deep-sky.
Asia
Singapore · Singapore
Southeast Asia · ~1.4°N · city access hub
Urban Singapore needs careful transparency and light-pollution planning before chasing faint targets. Equatorial nights still deliver frequent ISS passes and bright planet alignments year-round.
Jakarta · Indonesia
Java · ~6.2°S · city access hub
Tropical Jakarta nights fight dew, monsoon cloud, and dense urban glow along Java’s north coast. When the dry season settles, equatorial Milky Way hours return for highland escapes inland.
Bangkok · Thailand
Central Thailand · ~13.8°N · city access hub
Bangkok’s heat island and haze favour bright objects unless you drive toward drier northeast or Gulf coasts. Cool-season nights (Nov–Feb) bring the year’s best transparency.
Manila · Philippines
Luzon · ~14.6°N · city access hub
Manila Bay haze and metro light make Tagaytay and Cordillera escapes the practical dark-sky play. Typhoon-season breaks can leave superb transparency for a night or two.
Kuala Lumpur · Malaysia
Peninsular Malaysia · ~3.1°N · city access hub
Kuala Lumpur’s equatorial convection builds towering afternoon storms that sometimes leave pristine late nights. Highlands toward Genting and Cameron open darker horizons than the Klang Valley floor.
Tokyo · Japan
Kantō · ~35.7°N · city access hub
Tokyo’s skyglow is intense, so Okutama, Bōsō, and Izu dark sites define real deep-sky nights. Winter Siberian highs deliver the sharpest transparency of the year.
Seoul · South Korea
Korean Peninsula · ~37.6°N · city access hub
Seoul’s dense light dome pushes observers toward Gangwon mountains and west-coast islands. Cold continental winters bring long nights and occasional crystal Siberian air masses.
Mumbai · India
Konkan coast · ~19.1°N · city access hub
Mumbai’s monsoon and coastal haze dominate half the year, so post-monsoon winter nights are the serious season. City light pushes deep-sky work toward Western Ghats ridgelines.
Delhi · India
Indo-Gangetic Plain · ~28.7°N · city access hub
Delhi winters can be cold and clear aloft yet smothered by fog and pollution near the ground. When air quality improves, northern winter constellations and bright planets put on a strong show.
Dubai · United Arab Emirates
Persian Gulf · ~25.2°N · city access hub
Dubai’s desert air can be razor-sharp when dust settles, yet city megawatt glow and humidity spikes dominate. Inland desert reserves reward drives on moonless, post-shamál nights.
