Conditions at St Ives in July
July: Peak Summer Doldrums
July is the heart of the summer doldrums. Average swell height is 1.2m (4ft), and the average period drops to 8.2s - the shortest of the year. The wave rose shows a huge concentration from W (37.7%) and WSW (20.8%), with WNW (16.4%) still the preferred direction, but the vast majority is small, short-period stuff. This is groveling territory: fun for a log, frustrating for a shortboard. Wind-wise, W (12.3%), WNW (11.9%) and NNW (11.8%) are the most common directions and all are onshore or cross-onshore for a beach facing north-northwest. The positive is that offshore winds from SSW (7.0%), SW (8.9%) and WSW (11.5%) still show up often enough, especially in the early hours. Ideal conditions check in at 17%. With water temperatures at a warm 16.5°C and air temps averaging 16.3°C, the main draw is the rare clean summer swell event rather than everyday consistency. If you can find a SSW offshore and a leftover WNW swell, St Ives can still produce some playful waves.
