Twelve-month climatology dataset featuring long-term averages for temperature, humidity, and rainfall.
The climate profile for Guidimouni Lake utilizes NASA POWER measurements from 1991 to 2020 to establish consistent atmospheric expectations. This dataset provides a representative coordinate analysis of monthly mean temperatures, average precipitation, humidity, wind speed, and daylight hours. These figures represent long-term regional patterns rather than live weather, providing a structured look at the annual environmental rhythm at this site.
