Conditions at Shipwreck Bay in July
July: Depth and Difficulty
July is statistically the least ideal month for wind at Shipwreck Bay, with offshore flow only 18 percent of the time. The average swell remains heavy at 7-8ft (2.3m) on 12.2s, but quality diminishes as WSW swell becomes the second-most dominant direction at 12.2 percent behind SW at 28.2 percent. S and SSW winds are still present at 6.9 percent and 9.2 percent, yet the growing frequency of W, WNW, NW and NNW winds means more cross/onshore contamination. Add the annual peak rainfall of 4.25mm/day and water temp of 14.6°C, and you get a month of high-energy storms and very narrow windows. For the dedicated crew, an intense southerly change after a deep Tasman low can still line up some of the heaviest, most explosive waves of the winter-but expect to be picky.
