The Lowdown
Right, mate, Rusty here. Let’s have a look at the next couple of weeks.
Not gonna lie, it’s a tough run. The forecast is basically a long stretch of poor surf conditions with no real standouts. The first bit of clean surf that might get you out of the water is a long way off. The Breakwater-St Ives is a point break that’s inconsistent, and it’s set to be a frustrating wait.
We kick off on Tuesday, the 4th of August, with a 4ft swell from the SW, but that 16 mph cross-off wind is a bit of a spoiler, and the period is a short 7 seconds. The combined energy is weak (194). The water is 64°, which is a touch warmer than normal for this time of year. It’s a no-go, though. The next few days are the same story: Wednesday the 5th gets a bigger 7ft W swell, but the wind is howling 22 mph and cross, making a mess of it. That’s borderline expert-only size, but the quality is poor.
Thursday the 6th and Friday the 7th are tiny, with swell dropping to 1.0ft and weak energy. Saturday the 8th morning is glassy, but the swell is a mere 1.0ft from the WNW. There’s nothing to ride. We keep seeing “poor surf conditions” written all over the data. The combined energy barely gets into three digits on a few occasions, like Wednesday the 5th afternoon (246) and Thursday the 13th (235 to 273), but the wind is always cross or cross-on, keeping it choppy and messy.
The best of a bad lot looks like Wednesday the 19th of August. The morning sees a 4ft WNW swell with a 9-second period, and the combined energy climbs to 439 (moderate). But the wind is a cross-on 16 mph, so it won’t be clean. The afternoon drops to 3ft and 174 energy. Still, that’s the most energy we see in the whole window. Because the wind isn’t offshore, it’s not a true standout.
Honestly, for the whole 16-day run, there’s not a single day I’d paddle out for. The conditions are consistently poor, the swell is either too small, too short-period, or blown out. If you’re a kite surfer, the stronger wind days on the 5th and the 14th might look more interesting than a paddle session. For us surfers, it’s a blank run. It’s a bit of a bummer, but it happens. Forecasts can change, but right now, I’d be taking a break.
Rusty.
