Conditions at Watergate Bay in July

July: High Summer Haze

July is the lowest energy month of the year. Average swell height drops to 3ft (1.0m) and average period bottoms out at 8.3s, so long-period groundswell is almost absent. The swell direction is actually ideal - W at 48.9%, WNW at 21.1%, and WSW at 12.9% - but the heights are tiny, with the vast majority of readings in the 2-5ft (0.5-1.5m) range and many below 3ft (1m). The bigger problem is wind: only 16% of the time does it blow from an ideal offshore direction, while WSW/W/WNW/NW onshore flows combine for over 40% of the month. High pressure often delivers sunny skies and summer warmth, but it also kills the swell-generating lows. Air temp averages 16.4°C, water temp is warm at 16.7°C, and precipitation is 2.52mm/day. On a good morning, with an ESE breeze and small NW swell, you can still find clean longboard waves.
