The Lowdown
Alright, let’s break down what’s coming for San Gallan. To be honest, mate, this 16-day forecast is a bit of a struggle. You’ve got a solid reef break that usually loves a good southerly swell, but the wind is just not cooperating. Nearly every day we’ve got onshore or cross-onshore winds, and that’s ruining the wave faces. The water is sitting at a very unusual 70°, which is a whopping 9° warmer than average for this time of year—that’s a weird one.
We start on Saturday the 12th with a 5ft southerly swell, but a fresh 19 mph south wind is blowing straight onto it, making it unsurfable. The combined wave energy is moderate (243), but it doesn’t count for much with that wind. Sunday and Monday are more of the same—the swell actually gets a bit bigger, hitting 7ft on Sunday afternoon (moderate to strong energy at 411), but the wind stays on it. Anything over 5ft is getting heavy for beginners, and with the chop, only the experts should even think about it.
From Tuesday the 15th, the swell drops right off, down to around 3ft with very weak energy (146), and the wind is still messy. By Wednesday and Thursday, we’re looking at tiny 2ft to 3ft waves with energy readings well under 100. It’s flat and choppy.
We get a little pump around Tuesday the 22nd, with a 6ft southerly swell and moderate energy (282), but again, the wind is on it. Then on Wednesday the 23rd, we finally see a day that isn’t a total zero, but it’s still only marginal. A 4ft swell from the SSW with a light 6 mph south wind gives the cleanest conditions we’ll see, but the energy is still moderate (218).
The real kicker comes on Friday the 25th. We see a 3ft swell, but get this—a 12-second period from the south, and the combined energy jumps to 405. That’s a proper groundswell with some serious push, but the afternoon kicks up a fresh 19 mph cross-onshore wind, turning it into a lumpy mess. The morning might have been a clean window, but the data just shows poor conditions.
After that, the last few days fade into tiny, weak surf with light winds, but still cross-onshore. There’s no standout session here. The only day worth a look is the morning of Wednesday the 23rd, where the light wind and moderate SSW swell might offer a clean, small wave. For the rest, it’s a long, frustrating wait. If you’re into kiteboarding, the wind and chop on the bigger days might be your thing, but for a surfer with a paddle, you’re better off finding something else to do.

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 San Gallan 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.
