Data Sources for Botswana

Every figure on this page is sourced from official, openly published climate datasets. Anomalies are calculated against the 1961–1990 baseline (temperature) and 1991–2020 (rainfall, sunshine, frost) - see the Methodology & Sources page for the complete dataset list and update calendar.

FAQs

FAQs

How is the climate in Botswana changing?

Botswana 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 Botswana?

Botswana has a arid climate (Köppen BSh: Hot steppe), with both a warm/cold cycle and a wet/dry cycle through the year. November is typically the warmest month, averaging 26.7°C, while July is the coldest at 15.2°C. Annual precipitation averages around 379mm, concentrated mostly in the wet season.

Where does the climate data for Botswana come from?

Climate data for Botswana 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 Botswana climate data cover?

The Botswana climate profile covers Gaborone, Francistown, Molepolole, Serowe and surrounding areas. Temperature, rainfall and emissions data for Botswana

How often is the Botswana climate update refreshed?

The Botswana 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 Botswana 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 Botswana 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.
