Traveller notes on Isle of Wight in December
Other months in Isle of Wight
The forum's line on July is that the island runs a little kinder than the mainland — regulars who have come every July for decades describe usually just the odd bad day — but they are equally clear there is no predicting it: 15°C, 25°C or 35°C are all on the table, so check the forecast three to five days out rather than pack on hope. The real July averages are mild rather than hot, near 21°C with lows around 15, and the sea is a bracing 16°C. Two local pointers worth having: the west side of the island is usually the warmer half, and Ventnor is the summer base while Ryde suits the off-season.
