The Lowdown
Alright, let’s get into it. Rusty here, looking at the 16-day window for The Breakwater-St Ives.
To be straight with you, this stretch is a tough one. The forecast shows a long run of poor surf conditions with no real standouts worth paddling out for. The first few days from Friday the 17th through to the end of the first week are all showing poor surf – waves are small, mostly around 1 ft to 3 ft, with a lot of onshore wind and choppy conditions. The wind’s coming from the north and northeast mostly, which is wrong for this spot – it’s onshore and cross-onshore, so the face is going to be messy. The combined energy is weak, staying under 100 (23 to 86), so there’s just no punch.
The water temperature is about average for the time of year, nothing unusual there.
Moving into the second week, things don’t really improve. Saturday the 25th and Sunday the 26th see a bit more size – swell heights around 5 ft to 6 ft from the WNW, with periods of 6 to 7 seconds, so it’s short-period wind swell. The energy picks up into the moderate range (209 to 280), but the wind is still cross-onshore from the NNW at 12 to 15 mph, making it choppy. The wave comment still says poor surf. This setup is more interesting for kite surfing than paddle surfing – the beach-and-reef setup with strong cross-onshore wind and a bit of size is kite-friendly.
From the 27th through to the 1st of August, it’s back to small stuff – 2 ft to 4 ft – with wind staying onshore or cross-onshore, and energy dropping back under 150. The Breakwater-St Ives is already an inconsistent point break, and this whole period is a blank run. There’s no good surf on offer within the 16-day window. Given the area, it’s not unusual to have a dry spell like this – forecasts can change, but right now, there’s nothing to get excited about.
