August: Still Small, but the Atlantic Stirs
August is the last month of the summer doldrums, and the numbers tell the same story: average swell 0.7m (2ft), period 6.0s, and a persistent NNE texture. The NNE swell source is still massive at 20.9%, though NE, E and ESE all contribute to a mixed, low-energy sea. There is a slightly better chance of 1-1.5m (4-5ft) waves compared to July - especially from the NNE - but the majority of the month hovers in the small, fun-sized category.
The late-summer pattern also brings the first hints of change. Ideal surf wind ticks up to 26%, with a healthy W/WSW/SW flow, as Atlantic frontal systems begin to brush the British Isles more often. Water temperature peaks at 15.6°C, air temps average 15.1°C, and precipitation increases to 2.47mm/day - a sign of increasing autumnal activity. By the end of the month, an early-season low can fire up a worthwhile NE swell, offering a taste of the far better months ahead.
