Uluwatu Surf Forecast and Surf Report

Alright, Rusty here, let's talk about the coming swell window.

We’ve got a solid run of surf ahead at Uluwatu. The water temperature is sitting at 78°, which is just about bang on average for this time of year – nothing unusual there.

Tuesday morning (18 August) kicks things off with a clean 6 ft SSW groundswell, period a healthy 16 seconds. The wind is a cross-offshore breeze, so the waves will be groomed but not glass-smooth. The combined swell energy is a strong 2883 (moderate), so there's plenty of push. Tuesday afternoon cleans right up with full offshore wind, same size swell, and the energy holds. That’s a nice warm-up.

Now, Wednesday the 19th is where the juice starts flowing. We’re looking at a 8 ft to 8 ft SSW groundswell with a very long period of 17 to 18 seconds. That’s proper groundswell energy – waves with serious shape and power. The wind is solid offshore all day, keeping the faces clean. The combined energy jumps to between 3575 and 4113 (strong). This is advanced territory at 8 ft, but for those who can handle it, this is the standout session of the first week.

Thursday the 20th stays pumping with similar 8 ft SW swell, 16-second period, and offshore winds in the morning. The morning is the pick, as the afternoon goes a bit cross-offshore. Still excellent conditions for experienced surfers.

For the rest of that week and into the next, we’ve got a slow, steady drop in size but the quality remains high. From Friday the 21st through to Monday the 25th, we’re looking at 5 ft to 7 ft SSW swell, consistent offshore winds, and moderate energy levels. This is perfect for those who find the earlier stuff too big.

After the 25th, the swell drops a little more, with 4 ft to 5 ft SW swell and lighter winds. The period stays decent, but the energy dips into the moderate range (761 to 966). It’s still very good, just not the main event.

Now, keep your eye on late in the window. Sunday the 30th and Monday the 31st see a new pulse of SW swell, 7 ft to 8 ft, with a long period of 17 to 18 seconds and near-smooth winds. The energy jumps back into the strong range (3546). The real highlight, though, might be Tuesday the 1st of September and Wednesday the 2nd, where we’re looking at a solid 10 ft SW swell, 16 to 17 second period, and offshore winds. Combined energy is pushing 4635 (very strong). That’s expert territory, but it’s a big, powerful groundswell that will be a treat at the points and reefs. Mark that one down as a promising, long-range standout.

Overall, there are no gaps in the action here. The whole 16-day period has surf on offer. The first Wednesday (19 Aug) and that first week of September look like the absolute best, with consistent, strong, clean offshore conditions.

Signing off, Rusty.
