Long Set: Weather Today

📅 Monday, August 10, 2026
Today is definitely not the day for a trip to Long Set, as conditions are quite poor for any outdoor activities. We are expecting active thunderstorms throughout the day, which will make staying on the sand uncomfortable and potentially hazardous. The atmosphere remains very unsettled with heavy cloud cover and strong, blustery winds whipping across the coastline, creating choppy waters with noticeable waves. Given the significant risk of lightning and wet conditions, it is best to stay indoors and avoid the shore entirely until the weather clears. Even though the air temperature is a warm 29.5 °C and the water temperature is 29.9 °C, the incoming storms mean the beach is not a safe or enjoyable place to be today.
