Sources and checks for this page
Live readings come from METAR reports from the aerodrome at Cayenne/Rochambeau Arpt. Monthly means and every record on this page are computed from NOAA GHCN-Daily observations stored per station, per year, per month, and the capital list is GeoNames, CC BY 4.0. Nothing here is modelled, interpolated or estimated, and a month the archive never covered is left out rather than filled in. See how this is built.

What is the weather in Cayenne right now?+−
80.6°F at Cayenne/Rochambeau Arpt, measured at 00:30 local on Friday, 13 November 2026. This is the live reading from the station this page reads, after our quality checks. It is an observation rather than a forecast: it says what the weather IS, not what it will be.
When did temperature records begin in Cayenne?+−
The archive held here for Cayenne, French Guiana starts in 1950, which is 75 years of record, and 48,049 stored daily values, each one a maximum or a minimum.
Which station measures Cayenne's temperature?+−
Cayenne/Rochambeau Arpt (SOCA), 7 m above sea level. Every figure on this page comes from that one station rather than from a city-wide average, so it is a measurement at a known place rather than an estimate for an area.
How is the temperature measured and checked?+−
Readings arrive from METAR reports from the aerodrome and are quality controlled before they appear: a value outside a plausible range, or one that jumps further than air can move in the time between readings, is rejected rather than published. Every figure shows its source and the time it was observed.
Are there gaps in Cayenne's record?+−
The record runs from 1950 to 2025, and it is not equally deep across the year: the thinnest of the 12 months has 52 years of readings behind its average and the fullest has 55. Gaps are left as gaps: a month the archive never covered is omitted rather than filled in, which is why some months on this page carry no record.
Is Cayenne getting hotter?+−
In its hottest month it has. Across 54 Octobers between 1950 and 2023, the average October high at Cayenne/Rochambeau Arpt has risen about 0.2°F per decade. That is a straight-line fit through this one station's record: it is not corrected for a station that moved or changed instrument, and it is a description of the readings rather than a climate attribution.
How does Cayenne compare with other capitals?+−
It is the 68th warmest of the 230 capital cities with a full twelve months of record here, ranked on annual mean rather than on any single day, and 185th by the width of its annual swing. Papeete, Saipan, Yaren sit closest to it on that ranking.
When is Cayenne hottest?+−
October, averaging 89.4°F across the record, with February the coolest at 84.0°F. That is a swing of 5.4°F across the year.
