Nairobi
Stargazing tonight
East Africa · ~1.3°S·-1.29°, 36.82°·~Bortle 9 · Inner city
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.
Long rains and short rains set the real cloud calendar more than astronomy apps alone.
