The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day outlook for the Hikkaduwa area, centred on Inside Reef (Hikkaduwa). Right off the bat, I’ve gotta be straight with you – this one’s a tough read. The whole forecast window is a battle against the wind, and the waves that do show up are gonna be a rough, choppy mess for most of it.
The water temp is sitting about average for the time of year, which is a small mercy, but with the wind howling from the west and west-northwest day after day, the surface is going to be torn up. We’re looking at a solid run of poor conditions from the start, right through the first week and into the second. There’s no real stand-out, clean window to get excited about. The wind is consistently cross-onshore, often a fresh breeze of 15 to 22 mph, which is just no good for a reef break that needs that southwest optimum direction to line up.
Let’s break it down. From Friday 31 July right through to the end of the first week, the swell is all over the place. Friday morning starts with a 3 ft south-southwest groundswell with a super long 16-second period, but that 15 mph west wind is already cross-onshore, making it choppy. The combined wave energy is high (1109), but the quality is zero. Friday afternoon is the same story. Saturday 1 August sees a jump in size – 8 ft to 11 ft west swell – but the wind cranks up to 22 mph, and it’s lumpy. That’s a kite-surfing wind, not a paddling wind. Same deal on Sunday 2 August with 13 ft west swell (3072 energy) – it’s big, it’s powerful, but it’s a messy, blown-out wall. Monday 3 August drops a little to 8 ft, still with that nasty cross-onshore wind, and it’s only rated as marginal at best.
The middle of the week (4-6 August) sees the swell back down to 4 ft to 5 ft, but the period is long again (16-20 seconds), and the wind is relentless. The energy is still strong (1518-2315), but the comments are all “poor surf conditions.” It’s just not happening. The second week, from 7 August onwards, is more of the same. The wind is a constant 15-22 mph cross-onshore, the swell is dropping to 3 ft to 5 ft, and the energy stays moderate to strong (1063-2756). The mornings of 13 and 14 August show a bit of a pulse with 5 ft south-southwest swell and a 16-second period, but that wind is still cross-onshore, so the surface is going to be ugly.
So, to be honest, there’s no real standout. The only break we’ve got to look at is Inside Reef, and it’s just not firing under these conditions. The reef itself is a consistent, advanced-level wave, but with the wind direction being wrong for the entire 16 days and the swell direction often coming from the west instead of the optimum southwest, the sets are going to be messy and hard to read. The best you could possibly hope for would be a very early morning on 3 August or 14 August when the wind might be a little lighter, but even then, it’s marginal. For the rest of the time, honestly, this setup looks more interesting for kite surfing than paddle surfing. It’s a bleak run.
Rusty out.
