June: Winter Grip and Northwesterly Grooming
June brings a full winter grip to the Victorian coast. Average swell heights hold at 5-6ft (1.6m), the period stays in the powerful 12.0s range, and ideal wind frequency remains high at 27%. The windrose is the classic winter signature - strong NNW flow (16.6%) plus WNW and NW winds (11.9% and 10.8%) blowing offshore or cross-offshore across the SSW-facing beach. Onshore wind from the SSE-SW quadrant is down to 16.7%, meaning the surface stays far cleaner for far longer. Swell energy is led by SW (33%) and SSW (15%), with WSW (14%) and W (6%) adding a more westerly flavour; long-period groundswell is generated by intense Southern Ocean lows. Average heights around 5-6ft (1.6m) with occasional 6.5-8ft (2-2.5m) sets are common. Water temp cools to 12.4°C and average air temp is 12.0°C, so it's time for a winter hood and thick wetsuit - but 13th Beach serves up some of the most consistent, powerful surf of the year.
