The Lowdown
Alright folks, Rusty here, looking at the surf for the Sri Lanka region, specifically around Hikkaduwa. Let’s be straight with you – the next 16 days are a tough watch. The forecast is repeatedly calling it "poor surf conditions" for Inside Reef, so we’re in a waiting game.
The first real chance of anything ridable hits around Monday the 20th of July, but it’s not pretty. We’ve got a 4ft S swell with a very long 18-second period pushing in, giving us a massive 1876 combined energy reading. That’s a lot of power, but a solid 16 mph W wind blasting straight cross-on makes it a messy, choppy affair. The wind state is "moderate cross-onshore and choppy," and the wave comment is clear – it’s poor. This pattern just keeps repeating. That long period (18 seconds) means the swell is a groundswell, which can be tricky at a reef break like Inside Reef, but the wind is just ruining the shape.
Tuesday the 21st sees a similar story. A 5ft S swell drops to 15 seconds, energy is still high at 1131, but again that W wind blows cross-on. It remains marginal at best, just choppy and side-shore.
We drift through the rest of the week with nothing. The swell drops to 2ft, the wind does swing onshore, but the energy is gone – only 494 on the 24th of July. It’s a flat, blown-out period.
We get a little bump on the 26th of July with a 5ft SSE swell, period 11 seconds, and 977 energy, but the wind is back cross-on and it’s still "poor". This is the story for the whole first week – you’ll need to be a real glutton for punishment to get wet.
The most interesting window shows up at the very end of the month, but it’s for experts only. Looking at the 31st of July (Friday morning), we get a 5ft SSW swell with a 16-second period, building energy to 1601. The wind is still cross-on, but the bigger issue is the 1st of August. That’s when an 8ft W swell rolls in with a short 8-second period, and the wind cranks up to 19 mph. The combined energy hits 2330. That’s a beast, but with that short period and a full onshore wind, it’s a washing machine. It’s dangerous, messy, and only for the absolute best out there. For a beginner, anything over 5ft is too big, so this is a total no-go for anyone who isn’t a pro.
The water temp is about average for the time of year, nothing unusual to report there.
So, to be honest, there's no standout session here. The pattern is persistent wind and poor conditions. The 1st of August has the biggest swell, but the quality is zero. If you’re a kite surfer, that 8ft with an 19 mph onshore wind might look interesting, but for a paddle surfer, it’s a write-off. We’ve got a long gap of nothing but poor surf until that last few days, and even then, it’s grim. The blank run is normal for this area when the winds are this stubborn. Keep an eye on the long-range, but don’t hold your breath.
Rusty.
