The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for our little corner of the world.
For the next 16 days, it’s a real mixed bag. We’ve got a solid run of surf on the way, but it’s going to be a battle with the wind most of the time. The first few days are a bit of a write-off, but the second half of the period has a couple of windows that could be worth a paddle, especially if you’re an advanced surfer.
The first real chance to get wet comes on Tuesday, the 22nd of July. It’s not going to be a day to write home about, but there’s a little bit of energy in the water. The swell is from the SSW at 3 ft, with a period of 14 seconds, giving a combined wave energy of 471 (moderate). The wind is a gentle cross-shore from the WNW, which will keep the surface a bit messy but not totally blown out. It’s a marginal day, but it’s the start of something.
The next few days, from the 23rd through the 24th, are pretty poor. The swell drops off and the cross-onshore wind picks up, making things choppy. Not worth changing your plans for.
Now, things start to get a little more interesting around the 25th of July. The swell bumps up to 3 ft from the SW, with a much longer period of 21 seconds. That’s a proper groundswell, and the combined energy is a solid 1344 (strong). The wind is still a cross-shore, but it’s a gentle breeze, so it’s not too bad. This is a good setup for a reef break like Saint Annes, as the long period will wrap in nicely. It’s a fairly consistent spot, but it’s also one that gets crowded often, so expect company. The water temperature is average for this time of year.
The 27th of July is another one to look at. Swell holds at 4 ft from the SSW, with a 19-second period and a combined energy of 1352 (strong). The wind is a gentle cross-shore again. This is starting to look like a pattern.
The standout of the whole run, without a doubt, is the morning of Tuesday, the 28th of July. The swell bumps up to 5 ft from the SSW, with a 18-second period and a combined energy of 1609 (strong). The wind is offshore from the WSW, blowing at just 10 km/h. That’s the magic word right there – offshore. This is going to be glassy, clean, and the best the reef will look all forecast. The 5 ft is a solid size for an advanced surfer, and the long period means it will have plenty of push. This is the one to circle on the calendar.
The 29th of July looks okay in the morning, with a 3 ft SSW swell and a 16-second period, but the wind is a light cross-onshore. The afternoon turns glassy with a light offshore, but the swell drops a touch.
After that, from the 30th of July onward, the quality drops off. The swell gets smaller and the wind turns more cross-onshore. There’s a bit of a windswell from the WNW on the 31st, but it’s short period and messy. The first few days of August see a bit of a bump from the WNW, but the period is short and the wind is on it, making it poor.
So, the call is simple. Don’t bother before the 25th. The best bet is the morning of the 28th of July at Saint Annes. It’s the cleanest, most powerful option we’ve got. The 27th is a good backup. After that, it’s a waiting game.
Rusty.

Information about the Saint Annes Surf forecast
The above surf forecast table for Saint Annes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Saint Annes can be found by selecting the local surf guide option on the grey menu. Our Saint Annes 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 (Saint Annes) 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 Saint Annes 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.
Saint Annes is 4 km (2 miles) from Port San Luis. If you plan a vacation in San Luis Obispo, look for hotels and other accommodation in Port San Luis. Port San Luis has rooms for a wide range of budgets as well as car hire and transport links.
