July: Midwinter Energy And North Wind Woes
July is statistically the worst month for clean surf at Cat Bay, with ideal wind conditions at only 17%. The ocean, however, is not small: average swell height jumps to 1.6m (5.2ft) at 12.6s, and nearly 40% of the total swell distribution sits in the 1.5-2.5m (5-8ft) range. WSW becomes the second-biggest swell source at 21.2%, behind SW at 33.6%, and NW/NNW swell reaches 5.1% each, giving some real northwest-window energy. But the wind signal is brutal. NNW blows 25.6% of the time, NW adds 11.4%, WNW 10.5%, and W 7.5%, combining to blow out most sessions. The water is winter-cold at 13.4°C and air temperatures average only 11.4°C. This is a month for surfers chasing heavy, raw winter swells with a serious offshore-wind gamble.
