The UV index in Phuket, Thailand can vary dramatically through the day, especially in summer or at high latitude. This page shows today's UV index hour-by-hour, calls out the peak UV time, and tells you how strong sun protection needs to be at each hour. We use the World Health Organization UV index scale (0–11+) so values are directly comparable to UV forecasts you might see in apps or on the news. The page also shows tomorrow and the rest of the week, so you can plan beach days, hikes, sightseeing or sports in Phuket around safer UV windows. Sun safety advice is tailored to the actual UV reading: at low UV you need little protection, while at very high UV in Phuket you should reduce time outdoors during peak hours. This is especially relevant for fair-skinned visitors and for outdoor activities at altitude.
