Throughout the year, the UV Index undergoes significant changes, indicating varying levels of sun exposure risk. From January to February, UV levels start low, with a minimum risk of sunburn. However, as March approaches, UV levels rise to a moderate level of 5, marking the transition into higher risk months. The summer months of May to August experience the peak UV intensity, with values reaching up to 9, classified as very high, resulting in a burn time of just 15 minutes.
