UV index at 11.4 in Singapore means extreme risk: limit outdoor time especially from 10 a.m. to 4 p.m., actively seek shade, wear protective clothing, broad-brimmed hat, apply SPF 30+ sunscreen every 2 hours, and wear UV-blocking sunglasses. Watch for bright surfaces like water and snow increasing UV exposure.
Singapore's UV index is usually very high throughout the year, often ranging from 8 to 12, meaning the sun's rays are strong and the risk of sunburn is significant almost every day. Singapore experiences a tropical rainforest climate, so it is hot and humid year-round with temperatures between 26°C and 32°C. It has no true seasons but sees more rainfall from November to January due to the Northeast Monsoon and slightly drier months from February to April. Compared to its neighbors like Malaysia and Indonesia, Singapore tends to have a more consistently hot and humid climate without much temperature change. It also receives similar heavy rainfall amounts, but its small size means weather conditions are quite uniform across the city-state.
