Conditions at Porzcarn in July
July: The Doldrums Dig In
July is the heart of the low season at Porzcarn. Average swell height sits at a marginal 3ft (1m), average period drops to 8.5s, and ideal offshore wind plummets to just 12% of the time. Even though W (34.4%) and WNW (33.2%) directions dominate the waverose, together with WSW (13.3%), nearly all of the swell is small, disorganised, short-period residual energy. Onshore flow out of the W, WNW, NW and NNW quadrants is rampant, making most afternoons a choppy, mushy mess. Water temp reaches 17.1°C, air temps average 17.4°C, and precipitation is lowest of the year at 1.62 mm/day, so the beach is inviting; just don't expect much push. Your only real hope is a rare pattern that delivers offshore ENE-E-SE winds and a small but clean WNW swell in the early morning, when the ocean is still glassy.
