The Lowdown
Alright, grab a coffee, cause I gotta be straight with ya. The next couple of weeks are looking pretty grim for The Breakwater-St Ives. We’ve got a long, flat, and messy stretch ahead before anything even thinks about showing up.
The first real chance of a wave doesn’t come until Friday the 28th of August. That’s a long way off, more than a week from now. Before that, it’s a whole lot of nothing. We’re talking a solid ten days of rubbish, from the 16th right through the 27th, with tiny swells, onshore and cross-onshore winds, and just general chop. The energy readings are weak, mostly in the double digits, like 39 or 41, with a couple of moderate blips mid-period, hitting 130 and 139 around the 17th and 18th, but that doesn't matter because the wind is just ruining any chance of a clean face. It’s the kind of stuff that gets you excited for a flat day, and that’s saying something.
But hold on. We’ve got one standout, and it’s a proper little gem if it lines up. Friday the 28th, first thing in the morning. That’s when the charts light up. We’re seeing a solid 8ft of west swell, with a period of 10 seconds and a combined energy score of 1048. That’s a strong pulse of energy, no question. The wind is a light, cross-offshore breeze, which should keep it clean. The wave comment even calls for "very good surf conditions." For a spot that’s inconsistent like this, this is the one to circle on the calendar. It’s a bigger swell, over 8ft is expert territory, but at 8ft it’s pushing the limits for anyone not comfortable in proper waves. This is a point break, and that west swell direction is spot on for it. This will be a day for the crew who know what they’re doing.
The afternoon of the 28th drops off to 5ft with the same clean conditions but less energy (413), and the morning of the 29th is smaller again. So really, that Friday morning is it.
I’ll be honest, it’s a tough run. It’s a wait-and-see game, but that one morning has got some potential to be proper. Keep an eye on it, but don’t hold your breath for anything else. The water temp is about average for this time of year, nothing wild there.
Rusty out.

Information about the The Breakwater-St Ives Surf forecast

A general guide to surfing at The Breakwater-St Ives can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for The Breakwater-St Ives may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
