Typical Climate – Senegal
Köppen BSh · AridSenegal has a arid climate (Köppen BSh: Hot steppe), with both a warm/cold cycle and a wet/dry cycle through the year. May is typically the warmest month, averaging 32.3°C, while January is the coldest at 25.9°C. Annual precipitation averages around 685mm, concentrated mostly in the wet season.
Monthly climate normals (2016–2025) - bar colour and height show average temperature, the shaded area shows average monthly precipitation.

Heatwave Days – Senegal
Warm Spell Duration Index (WSDI) - the WMO/ETCCDI heatwave measure: days in a 6+ day run above the local 90th-percentile temperature for that time of year.

FAQs
FAQs
How is the climate in Senegal changing?
Senegal is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
What is the climate like in Senegal?
Senegal has a arid climate (Köppen BSh: Hot steppe), with both a warm/cold cycle and a wet/dry cycle through the year. May is typically the warmest month, averaging 32.3°C, while January is the coldest at 25.9°C. Annual precipitation averages around 685mm, concentrated mostly in the wet season.
Where does the climate data for Senegal come from?
Climate data for Senegal comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Senegal climate data cover?
The Senegal climate profile covers Dakar, Touba, Thiès, Rufisque and surrounding areas. Temperature, rainfall and emissions data for Senegal
How often is the Senegal climate update refreshed?
The Senegal climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
What counts as a Heatwave Day on the Senegal climate page?
Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.
Does the Senegal climate page include frost and snow data?
Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
