The Lowdown

G’day, Rusty here. Look, I’m gonna level with you straight up – this 16-day window for Inside Reef (Hikkaduwa) is a tough one to call. The forecast is a long, drawn-out affair of messy conditions. The southwest monsoon is hammering the coast, and for the most part, the wind is straight onshore from the west or cross-onshore, with a steady breeze of 9 to 16 mph. That’s going to put a chop on everything.

The water temp is sitting about average for this time of year, so no shock there.

We kick off Sunday, 19 July, and it’s all risk of thunderstorms. The swell is a weak 3ft from the SSW at a long 13 seconds, but with that 16 mph onshore wind, the wave energy is moderate at best (504). It’s labelled as poor surf, and I don’t see a single standout session in the first week. Monday the 20th gets a bit of size, with a 4ft to 6ft south swell, but it’s still cross-onshore and choppy. The energy jumps up (1902), but it’s a messy, marginal affair.

The whole first week is a bust. The second week, from 27 July onward, is more of the same: onshore wind, messy conditions, and a lot of thunderstorm risk. There’s a pulse of bigger swell on Friday, 1 August, with 6ft from the SSW, but it’s still onshore at 16 mph. The energy is strong (2443), but the quality is just poor. For a reef break like this, you need clean, offshore wind to make it shine, and we’re just not getting it.

Honestly, if you’re a kite surfer, this setup might look interesting. For a paddle surfer, there’s nothing here to get excited about. The crowds are only *sometimes* a problem, but that’s because the conditions are so ordinary. For a consistent, advanced reef break, this is a disappointing run. The only real hope is that the forecast can change, but as it stands, I’d save your energy.

Rusty.
