The Lowdown
Right then, let’s have a look at what’s on offer for The Breakwater-St Ives. This is a point break that’s inconsistent, so it needs the right conditions to fire. The water's sitting at 65°, which is a touch warmer than normal for this time of year.
The outlook starts with a long stretch of pretty grim surf. We’ve got a few days of poor conditions from Tuesday 11th August right through, with small, weak swell and not much to get excited about. You’ll see some clean waves on Wednesday 12th afternoon with a glassy 3 ft west swell, but it’s very ordinary.
The real action starts to build from the second week. On Thursday 20th August, the swell pushes up to 10 ft from the WNW, but it’s a short period of 8 seconds and the wind is cross-onshore, so it’s messy and only for experts. The energy is strong though, with readings of 1258 and 1001.
The standout is Sunday 23rd August. The morning brings a 8 ft WNW swell with a clean cross-off wind from the SE. The combined energy is a solid 765, and conditions are clean. This is the best on offer – a good size, decent shape, and the wind is right. The afternoon stays clean with a 7 ft WNW swell, but the morning is the pick. Expect some crowds though, as it’s a popular spot when it’s on.
After that, Monday 24th August sees the swell drop to 5 ft with a clean cross-off wind, but it’s only marginal. Then the wind picks up again, and the forecast gets messy with strong cross-off winds and lumpy conditions.
So, overall, a long wait for a decent session, but Sunday 23rd August is your best bet. The inconsistent nature of the break means you’ll need to be ready to go when it’s good.
