West Palm Beach 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 32°C most of the year. About 74 days a year above 32 °C.
Even the coolest nights stay near 14°C.
About 1568 mm of rain a year. Wettest in August.
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. West Palm Beach'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:

West Palm Beach 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 West Palm Beach's climate type changed?
Stable — West Palm Beach's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
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 West Palm Beach's measured 30-year climate normals (1991–2020) — the same official records behind West Palm Beach'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.
