Ao Sai Beach: Weather Today

📅 Sunday, August 9, 2026
Today at Ao Sai Beach is a mixed bag, making it a challenging day for those planning a full session by the water. You can expect mostly grey skies with some light drizzle passing through, which will definitely limit your time under the sun. With a maximum air temperature of 29.8 °C and a sea temperature of 30.4 °C, the water remains warm, though the breezy conditions and noticeable waves create a slightly choppy environment. Please keep in mind that the UV index is high at 8.25, so even behind the thick clouds, skin protection is absolutely necessary. While the water is warm enough for a quick dip, the combination of light rain and steady winds makes this an average day at best, so perhaps keep your beach visit short and flexible.
