The Lowdown
Alright, Rusty here again. Let’s break down the San Gallan forecast for you.
The water temperature is 69°, which is a wild 8° warmer than average for this time of year. That’s a major anomaly – feels like a bath, but don’t get your hopes up for the waves.
We’ve got a long dry spell to start. From Saturday the 15th through most of the following week, the surf is unridable. The swell is tiny, the period is short, and the wind is mostly blowing onshore or cross-onshore, making everything lumpy and choppy. Wave energy is mostly below 100 (weak), so there’s just nothing to work with.
Things get a little pulse on Tuesday the 18th afternoon, with the swell hitting 6ft from the S and energy climbing to 214 (moderate). But the wind is howling onshore at 25 mph, so it’s just a blown-out mess. That’s kite-surfing territory, not paddle surfing.
Wednesday the 19th sees the swell jump to 8ft in the morning and 8ft in the afternoon, coming from the SSE with a 9-second period. The energy is massive – 809 (strong) in the morning and 943 (strong) in the afternoon. That’s a lot of water moving. But again, the wind is onshore at 25 mph. This is strictly for experts. The size alone is too big for beginners, and the wind will make it a chaotic, dangerous wave.
The onshore wind eases on Thursday morning the 21st, dropping to just 6 mph from the SSE, with the swell at 4ft and a 9-second period. The energy is a moderate 215. The forecast says it’s marginal, and the tide might be a problem. It’s the best-looking window for a cleaner wave, but it’s still a long shot.
After that, the swell fades again. The rest of the month is small, weak swells (2ft to 3ft) with mostly onshore or cross-onshore wind. The one bright spot is Thursday afternoon the 27th, when the wind goes glassy. The swell is a tiny 2ft from the S with a 10-second period, but the energy is a moderate 153. With glassy conditions, you could squeeze out a few little peelers on a longboard, but it’s not going to be a day to write home about.
The final weekend (the 28th–30th) sees a swell bump to 6ft to 6ft from the S, but the period is short (7 seconds) and the wind picks up, chopping it all up. The energy is moderate to strong (340 to 353), but the wind keeps it from being any good.
Honestly, this is a tough stretch. There’s no standout day. The best hope is that Thursday morning the 21st, but it’s more of a prayer than a guarantee. San Gallan is a solid, consistent reef, but the wind has just been relentless. For this 16-day window, it’s a wait-and-see situation.
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.
