Conditions at Chesterman Beach in July

July: Summer Doldrums

July is the thickest part of the summer lull. Average swell height is down to 1.2m (3.9ft), still carrying an 11.4s period, but the wave heights rarely exceed the fun-size range. The swell direction is heavily WSW and W, so exposure is not the problem - wind is. The WNW and NW onshore flow becomes the dominant weather pattern, and with ideal wind sitting at just 9%, Chesterman spends most of its time with lumpy, wind-affected surf. That said, a morning offshore breeze can turn the long-period background into clean, waist-to-chest-high runners. Air temps peak at 14.6°C, water temp hits 14.0°C, and it is the driest month of the year with 1.59mm/day of rain. A good month for beach days and log rides, not for chasing power.
