The Lowdown
Alright, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks.
Right off the bat, I gotta be straight with you—this stretch is looking pretty flat and sad. We’ve got a long gap of nothing worthwhile to start. The first real shot at a wave comes up on Sunday the 23rd of August, but even then it’s a marginal call.
Thaila is a reef break, beginner-friendly, and it’s fairly consistent. The water is sitting at 71°F, which is a good 4°F warmer than usual for this time of year—so it’s gonna feel like a bath out there. The problem is the swell. For the first week, wave heights are tiny, mostly 1ft to 3ft, with a mix of cross-on and onshore winds that are just keeping things messy. The wind is light at times, but it’s never truly clean.
The best window we’ve got is probably the morning of Tuesday the 25th of August. There’s a 2ft SSW groundswell rolling in with a very long period of 16 seconds, and the combined energy is a moderate 361. The wind is a light cross-on from the WSW, but it’s a slight air—so the surface might be okay. Still, at this size, you’re not gonna be getting any barrels. The morning of Monday the 31st of August and Tuesday the 1st of September also show a slight bump in size to 3ft and 3ft, but the wind is cross-on and the sets will be inconsistent.
If you’re a beginner looking for a safe, small wave to mess around on, Thaila might be your spot, but don’t expect much. There’s no standout session here. Everything is marginal at best. The combined swell energy hits 472 on the morning of Wednesday the 2nd of September, which is the strongest of the run, but it’s still a 2ft swell with a 19-second period and cross-on wind from the south—that’s a lot of period for such a small wave, and it’ll be breaking straight and fat.
So, bottom line: we’ve got a flat spell with no real gold. The forecasts can change, but right now, keep your board in the car and your expectations low.
Rusty.

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.
