Conditions at Cape St Francis in July
July: Deep Winter Swell and the Search for Clean Windows
July is the heart of the winter season and the most challenging month for Cape St Francis. Average swell is 10ft (3.1m), period 12.5 seconds, and ideal wind is only 25 percent. SW dominates at 16.6 percent, SSW adds 9.0 percent, while S and WSW fill out the remaining directional spread. E swell is a mere 0.6 percent. The wind distribution is tilted toward strong westerlies, with W at 23.7 percent and WSW at 14.0 percent, but a significant NNW flow of 10.0 percent and NE/ENE contributions create plenty of messy surface conditions. Water temperature bottoms out near 16.7°C with air at 14.7°C. The long-period groundswell is huge, but most of it is aimed elsewhere; only the occasional E-leaning pulse and a hard W/SW offshore wind can turn this NE-facing break on.
