Conditions at Sandy Beach in August
August: Bottom of the Barrel
August remains deep in the summer doldrums, with an average swell height around 4-5ft (1.4m) and the shortest average period of the year at 9.8 seconds. The directional mix is still favorable - WSW (31.7%), SW (29.5%), SSW (14.1%), and W (9.3%) - but the period is borderline average, producing soft, crumbly waves rather than lined-up walls. Offshore flow is better than July at 29 percent, but WNW (12.8%) and NW (9.6%) still rule the wind rose. Water temps hit their annual high of 14.0°C and air temps average 13.3°C, which means the summer crowd enjoys the beach more than the surfer. It is a month for small-wave gear and patience.
