Conditions at Perranporth in July
July: Peak Summer Doldrums on a Sun-Drenched Atlantic Beach
July is usually the quietest month of the year for surf size at Perranporth. The average swell drops to 3ft (1.0m), the average period bottoms out near 8.3s, and the Atlantic behaves more like a lake than a storm factory. The direction distribution is still dominated by W (48.9%) and WNW (21.1%), but nearly all of it is small - a huge chunk of west swell falls in the 0.5-1m (2-3ft) range, with just a few 1-1.5m (3-5ft) waves. This is the heart of the Azores High season, when the North Atlantic storm track shifts toward Iceland and leaves Cornwall in the summer shipping-lane flatness. Offshore winds are at their annual minimum around 14%, while WSW and W winds blow over 24% of the time, so surface conditions are often lumpy. Still, warm air of 16.4°C, water at 16.7°C and plenty of summer sunshine make it a beautiful place to swim, learn, or ride a foamie through the whitewater.
