The Lowdown
Alright crew, Rusty here again, but this time in feet and knots. Let’s break down Middles/Generals.
To be straight with you, this forecast is a grind. There’s some solid swell on the way, but the wind is going to wreck it for most of the 16 days. It starts on Tuesday the 28th of July with some real size—7ft to 8ft of easterly groundswell, with a 13-second period, carrying a lot of energy (2058-2244). The problem is that cross-off NE wind is blowing at 16 knots. It’s clean, but that fresh breeze will mess with the surface. Water temp is about normal for this time of year.
Wednesday the 29th of July drops a bit to 7ft, shifting to NE, with a 10-second period. The wind goes light from the SSW at 5 knots in the morning, but it’s cross-on, making small ripples (1076 energy). Afternoon drops to 6ft, wind picks up to 8 knots and goes cross-shore, bringing a slight chop. Not great.
From Thursday the 30th of July all the way to Tuesday the 12th of August, it’s a long, ugly run. The wind locks in from the ENE, blowing 16 to 24 knots, mostly cross or cross-on. The swell stays between 5ft and 8ft, but with that strong breeze, it’s just blown out. Wave comments say “poor surf conditions” almost every day. The energy is moderate to strong (495-1314), but it’s all messy. Saturday the 1st of August has 8ft and 24-knot cross-on wind—that’s kite-surfing territory, not paddle surfing.
The only little window is Thursday the 6th of August in the afternoon. The wind goes light cross-off from the NNE at 13 knots, the swell is 7ft from ENE, but with a short 7-second period. It’s clean, but the score is a 1 out of 10—very marginal.
Best on offer? Tuesday the 28th of July morning is your best bet, with that 7ft to 8ft groundswell and cleanish conditions. After that, there’s a two-week gap until a light cross-off on the 6th of August. That’s a long wait.
Keep an eye on it, things can change. Rusty out.
