The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for Unawatuna over the next couple of weeks. Straight up, this is a tricky stretch. The swell energy is there, but the conditions are constantly fighting it, so we’re not looking at any classic days. There’s surf on offer almost every day, but a lot of it is just messy or tricky to line up.
First up, Monday the 3rd of August. A fresh 6ft W swell rolls in with a period of 11 seconds, producing moderate wave energy (1416). The wind is a brisk 22 mph from the west, making it a cross-off breeze. It’s clean-ish but that wind is strong, so it’s going to be a battle. The water’s sitting at 84°, which is a touch warmer than normal for this time of year – nothing crazy, just a bit of a tropical bath.
Tuesday the 4th offers a better chance. The morning brings a 6ft W swell with a 10-second period and moderate energy (1722). The wind switches to a WNW offshore at 16 mph, which is a major positive. It’s a moderate offshore breeze, so the waves should be reasonably clean. The afternoon sees a shift to a 4ft SSW groundswell with a very long 16-second period, giving solid energy (1233). That long period is great for this point break setup – it’ll draw in some well-shaped lines, but those long waits between sets will test your patience.
From Wednesday the 5th through to the following week, it’s a steady diet of risk of thunderstorms, cross-off winds, and consistent but mediocre surf. Swell heights sit between 3ft and 5ft, mostly from the S or SSW, with periods often above 14 seconds. The combined energy bounces between 1300 and 1900 – solid but not pumping. The cross-off wind direction (W or WNW) keeps the waves from getting that perfect glassy face, but it’s not totally blown out either. Expect clean but lumpy conditions.
Around Wednesday the 13th, we see a spike in size with 6ft from the WSW, but the period drops to a short 7 seconds, and the energy dips into moderate-low territory (822). That’s a windswell, bumpy and weak. Not the best.
The standout in this whole outlook? Honestly, with the constant storm risks and cross-off winds, there’s no single “go now” moment. But if you’re patient, Tuesday the 4th of August is your pick. The morning has that offshore wind and a solid 6ft W swell. It’s the cleanest window in the forecast. For the more experienced crew, the Thursday morning of the 6th brings 5ft S swell with a 14-second period and moderate energy (1704) – cross-off, but rideable.
Towards the far end, Tuesday the 18th of August shows a glimmer: 4ft S swell with a very long 18-second period and strong energy (1484). Some clouds, light cross-off wind – promising but a long way out, so don’t bank on it.
Overall, Unawatuna is serving up a lot of “almost there” surf. Take the Tuesday morning and be happy with a few clean ones.
Stay safe out there.

Information about the Unawatuna Surf forecast
The above surf forecast table for Unawatuna provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Unawatuna can be found by selecting the local surf guide option on the grey menu. Our Unawatuna 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 (Unawatuna) 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 Unawatuna 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.
Unawatuna is 3 km (2 miles) from Galle. If you plan a holiday in West Sri Lanka, look for hotels and other accommodation in Galle. Galle has rooms for a wide range of budgets as well as car hire and transport links.
