UV Index 🇸🇳Senegal

Senegal lies in tropical West Africa between roughly 12.3°N and 16.7°N, fronting the Atlantic Ocean along its entire western edge and sitting almost entirely at low elevation below 130 m. The country forms part of the Sahelian transition, with semi-arid steppe in the north around Saint-Louis grading into wetter Sudano-Guinean savanna and the forested Casamance in the south. At these latitudes the midday Sun passes close to the zenith for much of the year, so incoming solar UV traverses a short atmospheric path and remains intense throughout most months.

Senegal's Cape Verde peninsula at Dakar is the westernmost point of mainland Africa, jutting into the Atlantic where cool Canary Current air meets the continent. From November to March the Harmattan, a dry north-easterly wind off the Sahara, blankets the country in fine dust haze that significantly scatters and attenuates surface UV, while during the June–October monsoon thick convective cloud over Casamance and the Saloum delta further modulates exposure. The national meteorological agency ANACIM (Agence Nationale de l'Aviation Civile et de la Météorologie) operates the observing network underpinning Senegal's solar and UV climatology.

Senegal sits at #33 of 191 in the WHO's global ambient-UV ranking with about 5,356 J/m² of average daily UV, around the 83rd percentile worldwide.
