The tropical world is experiencing an unprecedented climate crisis. This is most often approached from the angle of excess or scarcity of rain. Temperatures are relegated to the background. However, they play a major role in the balance of environments.This article is a contribution on the phenomenon of climate change by focusing on thermal data. It puts in opposition a station close to the coast (Ziguinchor) and another more continental (Kolda). With simple tools (annual normal, seasonal and annual average, Pettitt and Mann-Kendal test), the recent thermal evolution of the study area was analyzed. This study shows an increase in temperatures since the 1970s, the existence of breaks and an increasing trend in the thermal series around the 1990s, but also a higher sensitivity of Ziguinchor to global warming.
