The Lowdown
Alright, let’s get into it.
The next couple of weeks at Thaila are looking pretty tough, mate. We’ve got a solid run of small, weak swell and the wind just won’t give us a proper break. The water’s sitting at 71.2°, which is much warmer than normal for this time of year, so at least you won’t need a thick suit. But honestly, you’ll be doing a lot of waiting and not a lot of riding.
The action, such as it is, kicks off on Saturday the 15th. There’s a touch of swell in the water, 3.3ft from the SSW, and it’s traveling on a long 16-second period, so there’s some energy in it, 602 on the combined scale. The problem is the west wind is blowing straight across it, chopping it up and making things messy. It’s not worth getting too excited about.
Sunday the 16th and Monday the 17th stay in that same zone – small waves, cross-onshore wind, and a lot of chop. We’re looking at 2.6-3ft, still with that long period, but the quality is just poor.
Then, from Tuesday the 18th through Saturday the 22nd, the wind finally goes offshore, which is a big positive. You’ll get cleaner conditions, for sure. But the swell drops right out. We’re down to 1.3-2.6ft, and the period drops too, meaning less push and less shape. There are a few ‘marginal’ windows in there where a longboard might catch a dribble, but it’s a lot of work for not a lot of reward. The energy readings are dipping into the low 200s and even 100s, which is weak.
The weekend of the 23rd and 24th sees a slight shift in swell direction, but the size is tiny, 1.3-1.6ft. The wind goes cross-on again, so it’s back to bumpy conditions. It’s a bit of a write-off.
The following week continues in the same vein. From the 25th to the 28th, it’s small, inconsistent, and mostly poor. There’s a slight bump in energy on the 27th and 28th afternoons, but we’re still only talking about 1.6-2.6ft surf with the wind being unhelpful.
Now, here’s the one thing that might get your attention. On Saturday the 29th, the morning looks much more interesting. The swell bumps up slightly to 3ft from the SSW, and the period jumps back up to 18 seconds with an energy reading of 777, which is the strongest we’ll see in this entire stretch. The wind is light offshore at 3 mph, which will make it glassy and clean. This is your window. It’s still not big, but for Thaila, this is the standout session. It’s a reef break, so that long period will create some nice, lined-up waves. But don’t get too attached to the idea; it’s a long way out and these calls can change. The afternoon turns a bit cross-on again, so the morning is the go.
Sunday the 30th drops back down again, with cross-onshore winds and more average surf.
So, to sum it up: the next 16 days are mostly a flop. The one bright spot is that clean, long-period pulse on the morning of the 29th. Get out there for that if you can. Otherwise, it’s a longboard and a lot of patience.

Information about the Thaila Surf forecast
The above surf forecast table for Thaila provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Thaila can be found by selecting the local surf guide option on the grey menu. Our Thaila 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 (Thaila) 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 Thaila 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.
Thaila is 1 km (1 miles) from Laguna Beach. If you plan a vacation in Orange County, look for hotels and other accommodation in Laguna Beach. Laguna Beach has rooms for a wide range of budgets as well as car hire and transport links.
