What this climate is like

Hot and wet every month, with no real dry season.

🌡️

Temperatures

Every month stays above 18°C (64°F) — there is no cool season at all. Daytime highs sit around 30–33°C (86–91°F) the whole year, and even nights rarely fall below 22°C (72°F).

🌧️

Rainfall and seasons

Rain falls heavily in every month — often 150–300 mm at a time — with no true dry season and consistently high humidity. Instead of hot and cold seasons, the year has slightly wetter and slightly less-wet stretches.

🌎

Where in the world

Found within roughly 10° of the equator: the Amazon basin, the Congo basin in Central Africa, the islands of Southeast Asia, and parts of Central America and the Caribbean.

What it means for you

Whether you're thinking of moving, gardening or travelling.

🏠 Living here

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.

🌱 Gardening

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.

✈️ Travel

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.
