The Lowdown
Alright, Rusty here again. Let’s talk in feet and miles.
Looking at the next few weeks, the surf starts slow and messy, but there’s some real juice coming later. The main spot is Grand Sancho, a beach and point break that’s fairly consistent and open to southwest swells. The water’s sitting at about 76°F, which is a touch warmer than normal for this time of year.
Monday the 17th of August is pretty average. Waves around 5ft from the SW with a very long 16-second period, giving the swell solid energy, but east winds at 15 mph are cross-shore and making it choppy. Tuesday the 18th is smaller and weaker – not worth paddling out.
There’s a dry spell through Wednesday and Thursday with poor to marginal waves. The swell fades and cross-shore winds stick around. By Friday the 21st of August, things clean up. The morning shows 4ft of SW groundswell at 14 seconds with a light cross-offshore breeze out of the ENE at 9 mph. That’s clean surf, decent energy, and the point should be shaping up nicely. This is your best early call.
Saturday the 22nd sees a bump to about 5ft–6ft SW, but the wind goes cross-shore again, adding a little bump.
Now the big stuff: Sunday the 23rd of August and Wednesday the 26th of August push 10ft of SSW swell with a 15-second period – huge groundswell energy (over 10,000 combined). But it’s just too big for Grand Sancho. The cross-shore wind and the size make it expert-only and sketchy. Not the day for a relaxed paddle.
Late August gets lumpy: the 28th sees 13ft SSW swell with fresh cross-shore winds, making it a mess. More for kite surfers.
The standout: Friday the 21st of August morning at Grand Sancho. Clean 4ft SW groundswell, light offshore breeze, and the point should be glassy. Crowds are sometimes an issue, but get in early and it’ll be worth it.
Also keep an eye on Monday the 31st of August morning – the swell drops back to 5ft from the SW, 16-second period, light east breeze. Clean, manageable, and good energy.
So, a lot of swell but only a few clean windows. The 21st and the 31st are your days. Rusty.

Information about the Grand Sancho Surf forecast
The above surf forecast table for Grand Sancho provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Grand Sancho can be found by selecting the local surf guide option on the grey menu. Our Grand Sancho 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 (Grand Sancho) 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 Grand Sancho 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.
