The Lowdown
Alright folks, Rusty here. Gotta be straight with you – looking at this 16-day window for Inside Reef (Hikkaduwa), it’s a tough one. Right now, and for most of the period, the wind is blowing onshore and the sea state is just messy. We’ve got a lot of days with poor surf conditions.
The first real chance to even think about getting wet isn’t until Tuesday the 21st of July. The morning will see a 5ft swell from the south, but it’s cross-onshore and choppy – more work than fun. The afternoon shapes up a little better with a 5ft south swell and the wind going gentle and onshore. The water is sitting at a warm 83° which is pretty normal for this time of year. It’s still only a marginal call at best.
Then we hit a long, frustrating lull. From Wednesday the 22nd right through to the end of the month, it’s all poor conditions again. Lots of risk of thunderstorms and that persistent onshore breeze. The swell is all over the place but never with the right wind.
Now, the last few days and into early August get interesting in size, but not in quality. On Thursday the 30th of July, the swell jumps to 5ft from the SSW with a very long 19-second period. The combined energy is massive (2373), but it’s still blowing onshore. That’s a lot of power with no order. By Saturday the 1st of August, the swell is pumping over 7ft from the SSW – that’s expert-only territory, and with the wind still on it, this setup looks way more interesting for kite surfing than paddle surfing. The swell period is long, which means it’ll be fat and unruly on this reef.
Bottom line: there are no standout days. Don’t plan your week around it. If you absolutely have to paddle, Tuesday the 21st of July afternoon is your pick, but keep the expectations low.
