The Lowdown
Alright folks, Rusty here. Let's get into it.
First up, the water at Main Reef (Hikkaduwa) is sitting at 83°F, which is pretty much normal for this time of year. No surprises there.
Look, I'm gonna be straight with you. The next 16 days are a real struggle for decent surf at Main Reef. We've got a solid run of poor surf conditions from the get-go, starting Monday the 31st of August and stretching all the way through to at least Sunday the 6th of September. The problem is a persistent cross-onshore or onshore wind pattern from the west, blowing 15 to 25 km/h, churning things up. The swell is there, but it's messy. You'll see a bit of a pulse on Monday the 31st with a 7 ft SW swell and a very long 17-second period, carrying a massive 2866 combined energy. But the wind is just no good, making it choppy and poor. The energy drops through the week, and we're looking at marginal or poor surf with the same wind issues.
There's a glimmer of a change on Wednesday the 2nd of September morning when the wind turns onshore from the WSW, but the surf is still rated poor. By Thursday the 3rd, the swell drops to 5 ft, and the energy is down to moderate levels. Honestly, for the first week, it's a write-off for quality waves.
The second week doesn't offer much relief. From the 8th of September onwards, we're stuck in a pattern of small, weak swells, mostly under 5 ft, with the same westerly winds. The combined energy is mostly in the moderate to low hundreds. The few times the wind is onshore, it's still not enough to save the day. The whole period is a blank run of poor conditions.
So, what's the best on offer? It's a tough call. If you're desperate, the early morning of Wednesday the 2nd of September has the wind turning onshore, giving the cleanest, albeit small, 5 ft SW swell. But it's a long shot. The later part of the 11th of September sees a slight uptick in swell to 5 ft with moderate energy, but the cross-onshore wind is still there.
Honestly, there's no standout session here. The consistent onshore flow and choppy conditions mean the surf is just not cooperating. It's a waiting game. Forecasts can change, but for now, don't expect much.
Rusty.
