Sources and checks for this page
Live readings come from METAR reports from the aerodrome at Cotonou/Cadjehoun 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.
7.6°F between March and August, the 163rd widest swing among the 230 capitals ranked here. The big figure on each card is the average high for that month across the whole record; the two lines beneath it are the hottest and coldest days ever recorded in it.

What is the weather in Porto-Novo right now?+−
75.2°F at Cotonou/Cadjehoun Arpt, measured at 19:00 local on Thursday, 12 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 Porto-Novo?+−
The archive held here for Porto-Novo, Benin starts in 1941, which is 84 years of record, and 49,057 stored daily values, each one a maximum or a minimum.
Which station measures Porto-Novo's temperature?+−
Cotonou/Cadjehoun Arpt (DBBB), 4 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 Porto-Novo's record?+−
The record runs from 1941 to 2025, and it is not equally deep across the year: the thinnest of the 12 months has 49 years of readings behind its average and the fullest has 62. 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 Porto-Novo getting hotter?+−
In its hottest month it has. Across 57 Marchs between 1941 and 2019, the average March high at Cotonou/Cadjehoun Arpt has fallen 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 Porto-Novo compare with other capitals?+−
It is the 58th 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 163rd by the width of its annual swing. Asunción, George Town, Hagåtña sit closest to it on that ranking.
Why is Porto-Novo hotter in March than in July?+−
March averages a high of 90.0°F here and July 82.8°F, so the hottest part of the year arrives 4 months before midsummer and the afternoons are 7.2°F cooler by the time the sun is highest. The month cards above show the rise and the fall. These are temperature readings, so they show that shape rather than what causes it: nothing on this page measures cloud, rain or wind.
