The Lowdown
Alright, Rusty here, let’s talk about what’s shaping up for the Hikkaduwa area. We’ve got a solid run of swell on the cards, but the wind and weather are going to be the real story. This isn’t a clean, easy forecast; the ocean’s going to be full of energy, but for the most part, it’s going to be a battle with onshore and cross-onshore winds. The water’s sitting at 83°F, which is about average for this time of year, so no surprises there.
The first decent window to even think about it kicks off on Tuesday morning the 18th. Hikkaduwa (A-Frame) will have a chunky 7ft swell from the SSW with a very long period of 19 seconds. That’s serious groundswell energy—we’re talking massive power, over 4000 in the combined energy reading. But, and it’s a big but, the wind is a moderate cross-onshore from the WNW at 12 mph. It’s going to be choppy and hard work. The period is so long that at a reef setup like this, it could be the saving grace, giving those long lines that reel off. The high tide and storm risk make this a marginal call at best. It’s not a beginner’s wave at this size; 7ft with that much push is for experienced surfers only.
Wednesday the 19th and Thursday the 20th are a write-off. The wind swings directly onshore, gusting up to 16 mph, with the swell dropping a touch to 6ft-7ft. The storm risk is high, and the surf quality is poor. Don’t bother.
We see a slight improvement into Friday the 21st and Saturday the 22nd. The swell backs off a little, dropping to 5ft-6ft from the S and SSW, with a period of 14-15 seconds. The energy is still considerable (around 1300-1500), but it’s still cross-onshore from the West. The mornings have clear skies, but the wind is still messing it up. It’s marginal, maybe a 1 out of 10 score. It’s not terrible, but it’s not good.
Sunday the 23rd is more of the same—5ft to 5ft swell, with the wind easing a touch to 9 mph in the afternoon. That gentle cross-onshore makes it only fairly choppy, but it’s still not clean. The period has dropped to 13 seconds, so it’s losing that long-range grunt.
From Monday the 24th all the way through to the end of the month, we are stuck in a pattern. The swell hangs around between 3ft and 6ft, but the wind almost never gets good. It’s a constant moderate cross-onshore or onshore breeze from the West and WNW. The surf quality is consistently scored as poor, and most days are stormy or cloudy. There are a few brief windows on the 25th and 28th afternoons where it might be just barely rideable, but you’d be fighting the chop. The combined energy fluctuates between 700 and 1700, showing moderate wave energy.
There is one last flicker of hope right at the end. On Saturday the 29th of August and Sunday the 30th, the swell bumps back up to 5ft-6ft from the SSW, with a very encouraging 15-18 second period. The energy is back up around 1500. The problem? Same wind. It’s still cross-onshore or onshore. The conditions are only considered marginal, even on the morning of the 29th. It’s tantalisingly close to being good but never quite gets there.
Looking at the first week of September, the swell drops a little to 4ft-6ft, but the wind stays stubbornly onshore or cross-onshore. The second of September afternoon has a 4ft swell with a 20-second period, which means it’s super long period. The combined energy jumps to 2274, indicating strong wave energy, which is interesting for the reef at A-Frame. But with the onshore wind forecast, it’s still a no-go.
The Verdict: Honestly, for this whole 16-day window, there’s not a single perfect day. The best chance you’ve got is if you’re an experienced surfer looking for power on the reef at Hikkaduwa (A-Frame). The Tuesday the 18th of August morning has the biggest, most powerful swell (7ft from the SSW at 19 seconds), and if you can handle the cross-onshore chop, you’ll find some serious energy. The other potential standout is the Saturday the 29th of August and Sunday the 30th morning, where the 5ft+ swell has a lovely 15-18 second period, but again, expect lumpy conditions. There are no standouts for clean, glassy waves in this forecast. If you are a beginner, these conditions are too messy and powerful.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Hikkaduwa (A-Frame) 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.
