Georgetown
Stargazing tonight
Demerara-Mahaica · ~6.8°N·6.80°, -58.16°·~Bortle 8 · City
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.
Dew and haze are the usual blockers more than long astronomical twilight.
