With the UV levels often peaking at a high of 11 around noon, awareness of these readings can help prevent sunburn and reduce long-term skin damage. Mwembe's Aw climate brings bright, sunny days, which, while delightful, also mean that exposure to harmful UV radiation increases, especially during midday hours.
