San Andros has a tropical rainforest climate.
Hot all year, with humid air and reliable rain — no real cool season.
What this climate feels like
The four things a regular visitor actually wants to know:
Daytime highs near 91°F most of the year. About 69 days a year above 90 °F.
Even the coolest nights stay near 65°F.
About 60 in of rain a year. Wettest in June.
A roughly even mix of sun and cloud.
What "tropical rainforest" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. San Andros's type — tropical rainforest — sits in the broad family of hot, humid climates near the equator.
Researchers write climate types as a short letter code. Here is what each letter means:
Cities with the same climate as San Andros
A tropical rainforest climate (Af) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
San Andros sits near a climate boundary
This city sits right on the line between tropical rainforest and the next type along. Different climate maps file it on different sides of that line; the lived weather doesn't change at the line — it's a naming boundary, not a wall.
Has San Andros's climate type changed?
A climate type is a coarse bucket. It can hold steady for years while the weather inside it shifts — or tip into the next bucket.
What this climate means for you
Things grow year-round — there is no frost and no dormant season. The challenge is excess moisture: mould, rot and fast weed growth. Tropical fruit thrives; temperate vegetables struggle.
Warm whenever you go, but there is no completely dry time of year. Check a specific city's monthly rainfall to find its least-wet window before planning an outdoor trip.
Heat and humidity are the everyday experience — warm nights, frequent rain, and no seasonal cool-down. Air conditioning is near-universal; airflow, shade and mould control matter.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from San Andros's measured 30-year climate normals (1991–2020) — the same official records behind San Andros's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
Methodology & sources
Temperature & precipitation — 1991–2020 normals computed from 20 years of daily observations at Nassau Airport New, a weather station, about 59 km from the city centre. The underlying daily records come from NOAA's global station network.
