Conditions at Nahoon Reef in July
July: Cold-Water Perfection and Big SSW Groundswell
July continues the winter rhythm with the same average swell height of 2.1m and the same 12.1s period as June. The swell window is dominated by SSW at 32.3 per cent and S at 16.3 per cent, and the 2-2.5m class is the most frequent of the year, with SSW putting 12.3 per cent there and another 0.5 per cent above 2.5m. This is heavy, powerful surf. The E/ESE/SE/SSE component at around 23.5 per cent is secondary, but when those directions combine with winter's cleaner winds, the reef's potential is unmistakable. Favourable wind sits at 46 per cent, with the W, WNW, NW and NNW block supplying a reliable offshore component; WSW at 15.9 per cent and SW at 9.5 per cent also keep many days cross-shore and tidier than the summer trades. Expect more hollow takeoffs and long, grinding walls when the sand and reef line up.
Air temperatures bottom out at 17.6°C, water temperature drops to 19.2°C, and precipitation remains minimal at 1.10mm/day. This is proper reef-surfing weather - bring the rubber and time your paddle for the set lulls.
