The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – this isn’t a week for charging. If you’re stuck on the idea of a wave, you’ll be fighting a cutter more than you’re riding one. The whole 16-day window is a rough patch of conditions, with a real lack of clean, rideable surf. There’s a big gap of nothing recommended, and even when the swell shows up, the wind is a mess.

The only spot on the cards is Inside Reef (Hikkaduwa). The water’s sitting at 83°, a touch warmer than normal for this time of year, so it’s a nice bath to be in while you’re getting chopped up.

We start Monday, 20 July, with a S swell at 4 ft, but it’s a long-period 18 seconds of groundswell. That’s good for shape on a reef like this, but the wind is a cross-on shore from the W at 12 mph, and there’s a risk of thunderstorms. The combined energy is massive – 1884 – but it’s all messy. The afternoon jumps to 6 ft S swell, 16 seconds, but same story. It’s a no-go.

Tuesday, 21 July, sees a similar story: 5 ft S swell in the morning, dropping to 5 ft from the SSW in the arvo. Periods are dropping from 15 to 14 seconds, but the cross-on breeze from the WNW at 12 mph keeps it ugly. Wednesday, 22 July, is worse – 4 ft S swell, 13 seconds, weak energy down to 621 in the morning, and the wind is still a cross-on mess. It’s poor.

Thursday, 23 July, the swell drops to 3 ft from the S, 12 seconds, and the wind is onshore from the W at 12 mph. The energy is a pathetic 451. This is a dead zone. This pattern of poor, choppy, cross-on slop runs right through until the end of July. By the 31st, the swell is picking up to 6 ft to 7 ft from the SSW, period 16 seconds, and the energy is smashing 2205 to 2451. But the wind is still cross-on or onshore, and it’s all a risk of t-storms. This is big, powerful, and completely blown out. For a reef, that’s a washing machine for experts only, and even then, it’s not fun.

Into the first week of August, the 1st has a 6 ft SSW swell, 15 seconds, with the wind flipping to a light onshore from the WSW. The guidance calls it “marginal” – the best we get, but it’s still a low-score day. By the 3rd, we get a mixed bag of a 6 ft WNW swell with a 7-second period – that’s short period, fat, and weak energy of 913 – and then a 4 ft SSW swell later. It’s all cross-on, choppy, and poor.

So the bottom line: there is no standout. There is no best day. The entire period is a battle against cross-on wind and poor surf quality. For a reef that needs clean conditions, this is a write-off. If you’re a kite surfer, the set-up of solid swell and strong wind might be your thing, but for a paddle, it’s a hard pass. The forecasts can change, but for now, leave the boards at home.

Rusty.
