Conditions at Sennen Cove in July
July: Small Summer Frequencies
July offers the smallest average surf of the year at Sennen, with just 4ft (1.2m) of swell and a short 8.2s average period. The swell distribution is overwhelmingly westerly: W is 37.7%, WSW 20.8%, and WNW 16.4%, but wave heights are heavily concentrated in the 2-5ft (0.5-1.5m) range, with 17.1% alone in the 2-3ft (0.5-1m) class. Clean days happen when an offshore S or SSW breeze lines up with a fading west groundswell, and ideal winds blow 12% of the time. However, typical summer high pressure brings a persistent NW/NNW sea breeze (NNW 11.4%, NW 9.7%) that can chop up the lineup. The reward is a pleasant environment: air temp 16.3°C, water temp 16.3°C, and no need for hoods or gloves. Bring a longboard, surf the morning push, and stay stoked.
