Conditions at Il Castello in July
July: The Summer Lull Deepens
July is as slow as it gets at Il Castello. The average swell height is 0.5m (1.6ft), the period is a limp 4.0s, and ideal offshore wind occurs only 9% of the time. WSW is the dominant swell direction at 21.0%, but 10.1% of that sits below 0.5m and another 7.2% is only 0.5-1m, so it is soft, windswell-affected and localized. Most of the region comes under a persistent summer high-pressure regime, with the thermal low drawing in onshore W and WSW flow - W is the top wind direction at 11.2%, with WSW next at 8.9%. These are exactly the conditions that produce crumbly, short-period, onshore waves. The water is warm at 24.2°C (75.6°F), air temperatures peak at 24.5°C and rain is scarce. This is a beach-beach, swim-and-sun month rather than a surf month.
