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. Layou's type — tropical rainforest — sits in the broad family of hot, humid climates near the equator.

The shorthand: Af

Researchers write climate types as a short letter code. Here is what each letter means:

A
Tropical — Every month averages above 18 °C — there is no real cool season.
f
Rain in every month — Heavy rain falls in every month — there is no dry season.

Cities with the same climate as Layou

A tropical rainforest climate (Af) — these recognizable cities share it. If you know one of them, you know roughly what to expect.

Layou 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 Layou'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

🌱
For gardeners

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.

✈️
For travellers

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.

🏠
For movers & buyers

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 Layou's measured 30-year climate normals (1991–2020) — the same official records behind Layou'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 — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.

Precipitation — 1991–2020 normals computed from 10 years of daily observations at LE Lamentin, a weather station, about 157 km from the city centre. The underlying daily records come from NOAA's global station network.
