Here you can request TAHMO data by filling in the form. Fill out the form and we will get back to you to help you with your project. Be sure to first view our geographical overview of weather stations through our School2School website. The link to the form will bring you to an external website hosted by the Oregon State University.
We also provide links to different sites with climate data for Africa. We have found daily and monthly, historic and real-time data available for the entire African continent.
African Climate Data Websites
Hourly DataHere you can find hourly data.
Data available on this website:– Temperature (mean) (°F)– Mean pressure (inch)– Relative humidity (%)– Mean visibility (mi)– Average dew point (°F)– Wind direction– Wind speed (mph)
Note: Not all stations provide hourly data, but daily, weekly and monthly data are also available on this website.
Daily DataHere you can find daily data. Select the country, then the station, then the year and month.
Data available on the website:– Temperature (mean, maximum and minimum) (°C)– Mean sea level pressure (hPa)– Relative humidity (%)– Rainfall (mm/day)– Mean visibility (km)– Wind speed (km/h)– Occurrence of: rain, snow, thunderstorm, fog.
Note: Some stations provide very complete daily data for fifty years. Other stations provide only incomplete data.
Monthly DataHere you can find monthly data over an average year. Click wherever you want on the map to access the local data, which are presented in a graphical format.
Data available on the website:– Temperature (mean, maximum, and minimum) (°C)– Rainfall (mm/day)– Wet days (day/month)– Ground frost (day/month)
Website 2:All Met Sat
Data available on the website:– Temperature (maximum and minimum) (°C)– Rainfall (mm/month)– Wet days (day/month)– Hours of sunlight (h/month)
Note: Some stations do not provide all of the data listed above.
The third and fourth websites provide monthly data presented in a tabular format.
Data available on the website:– Temperature (mean, maximum and minimum) (°C)– Rainfall (mm/month)– Ground frost (day/month)– Relative humidity (%)– Average dew point (°C)– Wind speed (km/h)
Website 4:UN Data
WMO website, very complete.
Climate Information Tool, Monthly DataThis tool provides data for any location in Africa, even if no weather station is available. The site interpolates data using weather stations that are within close proximity to your inquiry. Simply click wherever you want on the map to access it.
The database used for the interpolation is the GPCC (Global Precipitation Climatology Center) database. The stations are shown on the following map.
Data available:– Temperature (mean, maximum and minimum) (°C)– Relative humidity (%)– Rainfall (mm/day ; mm/month)– Coefficient of variation of rainfall (%)– Wet days (day/month)– Hours of sunlight (%)– Ground frost (day/month)– Wind speed (m/s)– Reference evapotranspiration (mm/day ; mm/month)– Historical data
Here you can find historical data; most have been recorded since 1945, and some before 1900.
The dataset available is very complete.
Current WeatherHere you can find current climate data.
These websites provide maps. The second website is very complete and provides data for different isobaric values.
At TAHMO we continuously improve our weather station. We upgrade older stations to new ones. One example is in Akure, Nigeria where the University just upgraded the weather station. Read more...
