Conditions at Millers in July
July: Cold Winter Classic
July is the coolest month and the peak of the winter groundswell regime. Average height holds at 7.9ft (2.4m), the highest of the year, with a 12.5s period that puts plenty of brute force into the bay. SW and SSW are nearly tied (26.2 per cent and 23.2 per cent), with S at 7.3 per cent. The over-8ft (2.5m) class is present, so big days are serious. Offshore wind windows remain scarce at 18 per cent. The wind rose is dominated by WSW/W (31 per cent combined) and by an onshore NNW/N/NE component totalling 25.7 per cent. Water temp drops to 17.7°C, air averages 15.9°C, and rain is 1.01 mm/day. If you get the wind right, the waves are incredible - heaving, long-period SW lines wrapping down the coast. The problem is the percentage play.
