The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for the St Ives area. Honestly, it’s a pretty grim stretch ahead. The Breakwater-St Ives is the only spot on the cards, and for the first week and a half, there’s barely a whisper of a decent wave. The surf is small, choppy, and the wind is all over the shop. You’ll be waiting a long time for anything rideable.
The first real chance doesn’t show up until Wednesday, the 12th of August. The morning brings a tiny 3ft swell from the west, with a period of 9 seconds, and the wind is offshore from the SSW, leaving the surface clean. The combined energy is weak though, at 176. It’s surfable, but very ordinary. The afternoon sees a stiff cross-offshore breeze, so it’s not getting any better.
Thursday, the 13th of August, has a bit more size. The morning has 6ft from the west, with an 8-second period, and a clean cross-offshore wind. The energy is moderate at 422. That’s the pick of the whole run, but it’s still only a marginal call. The afternoon turns ugly with a cross-onshore wind and chop. Friday the 14th and Saturday the 15th are all poor conditions or fresh offshore winds with tiny swell.
Then on Sunday, the 16th of August, the swell jumps up to 7ft from the west, but it’s 8-second period and cross-onshore, so it’s choppy and messy, with a strong energy of 544. That’s not for the faint-hearted. The rest of the run into the third week is all small, clean, or clean-ish, but the swell is barely ankle-high, with energy dropping below 100. The wind stays fresh, mostly cross-offshore, but there’s nothing to push you into a wave.
So, the standout, if you can call it that, is the morning of Thursday, 13th August at The Breakwater-St Ives. It’s a point break, inconsistent, and crowds are possible. The water is sitting at 65°, which is a touch warmer than normal for this time of year. The 6ft west swell with a moderate 8-second period and clean offshore wind is the only window where you’ll get a wave with a bit of push and a clean face. The rest is a write-off until the very end, and even then, it’s tiny.
There’s a long gap of nearly 10 days with no real surf on offer. It’s a tough block for the area. Conditions can change, but right now, I’d be checking the other spots inland.
