Understanding UV levels is essential, especially in a climate characterized by plenty of sunshine and dry conditions, such as Tamasane's BSh climate zone. With UV Index values reaching as high as 7 during midday hours, residents and visitors must be vigilant to shield themselves from harmful UV radiation. By monitoring these levels, you can enjoy the sun responsibly and protect your skin against long-term damage.
The UV index for the day shows a gradual increase in intensity, peaking at 12:00 PM with a notably high value of 7.

Throughout the year, UV Index values exhibit significant seasonal changes, with extreme exposure levels dominating the first half of the year. The months of January to April (UV Index 16 to 11) carry a high risk, requiring individuals to limit sun exposure to just 10 minutes to avoid burns. This trend continues with October and November again presenting extreme conditions, reiterating the importance of sun safety during these months. May and August mark a slight decrease to very high exposure, allowing for a 15-minute burn time, while June and July offer high UV levels, where one can safely enjoy the sun for 25 minutes. As a precaution, both residents and visitors should prioritize sun protection—such as using sunscreen, wearing protective clothing, and seeking shade—especially during high-risk months.
