The Lowdown
Alright, folks, Rusty here. Let's cut through the noise on the Gallan area for the coming weeks.
I'm gonna be straight with you, this is a tough one for the surfers. Over this 16-day stretch, it's pretty much a bust. The wind is just relentless, blowing onshore day after day, and the swell is either too small or too messy to make anything of it. It's a long, bleak run.
The only faint glimmer of hope is on Monday, the 10th of August. We see a pulse of swell come in, about 5ft from the SSW with a solid 14-second period. That's real groundswell, and the combined energy reading is a hefty 1049 (moderate wave energy). The catch? The wind is a light cross-onshore breeze. It's not clean, but it's the best thing we're going to see. The spot is San Gallan, a consistent reef, so it'll be breaking. The water is a wild 70°, which is a massive 9° warmer than usual. That's very unusual. A bit of a freak event. Still, with that wind, it's a marginal call. That 5ft is too big for beginners, but experienced surfers might find a few.
That Monday afternoon, the wind picks up to a moderate breeze and it's back onshore, so the window is tiny. The rest of the first week and into the second is just more of the same – onshore wind and deteriorating conditions. Tuesday the 11th has a similar swell, but it's either onshore or cross-onshore with moderate chop. By Wednesday and Thursday the swell drops off and the wind is still bad. The 14th of August Friday afternoon sees the swell down to 3ft and cross-onshore, and it just gets smaller from there.
From the 15th of August all the way to the 23rd, it's a flat, windy mess. The combined energy drops to under 100 (weak energy) for a lot of that, and the swell periods are pitifully short. For example, the 17th of August has a 4-second period and 3ft of swell – that's just wind chop. Even the bigger pulses later on, like the 23rd of August with 6ft, are ruined by a short 6-second period and cross-onshore winds. For a beach break, that's just a choppy, ugly mess. Honestly, this is looking more like a kite-surfing window than a paddle-surfing one.
So, the bottom line: there is no standout session. The best you can hope for is a grumpy, quick session on the Monday morning of the 10th if you're a local who knows the reef and can handle that cross-onshore bump. The outlook is poor for the entire 16 days. But don't lose hope, it tends not to stay this bad for long, and the forecasts can change. For now, I'd be doing something else with your time.
Rusty.

Information about the San Gallan Surf forecast
The above surf forecast table for San Gallan provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at San Gallan can be found by selecting the local surf guide option on the grey menu. Our San Gallan surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (San Gallan) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
San Gallan is 30 km (19 miles) from Pisco. If you plan a holiday in Ica, look for hotels and other accommodation in Pisco. Pisco has rooms for a wide range of budgets as well as car hire and transport links.
