The Lowdown

G’day, Rusty here. Look, I’ve been staring at the charts for this stretch, and I’m not gonna lie – it’s a tough run for Inside Reef (Hikkaduwa). The whole 16-day window from August 18th right through to September 2nd is a real battle. The wind is almost always cross-on or onshore from the west, and there are stormy skies or risk of thunderstorms most days. That means the surface is going to be choppy more often than not, and the surf quality is poor to marginal for the vast majority of the period. There are no standout sessions that I’d paddle out for with real confidence.

We start on Tuesday the 18th of August afternoon with a bit of a tease. A 7ft SSW swell is rolling in with a long 19-second period – that’s proper groundswell energy, good for a reef setup like this. The combined energy is strong, sitting at 3876. But the wind is a cross-on 12 mph from the WNW, and it’s labelled as choppy. The water temp is 83°, about 1° warmer than average, so it’s a touch warmer than usual for this time of year, but nothing crazy. Still, the conditions are marginal, and tide could mess things up.

From Wednesday the 19th through to the end of August, it’s pretty much the same story. Swell hangs around between 5ft and 7ft, mostly from the SSW, with periods between 14 and 17 seconds – plenty of energy in the water (combined energy ranges from 1334 up to 3497). But the wind stays stubbornly cross-on from the west at 9 to 16 mph, and it’s often accompanied by stormy weather. On a few mornings, like the 22nd and 23rd, the wind is listed as “on,” which might be offshore, but the overall conditions are still poor or marginal. Nothing cleans up enough to get excited about.

The second week, from around the 25th of August into early September, the swell drops off a bit, with heights between 3ft and 7ft. The period goes long again on the 29th with a 20-second groundswell, but that 3ft to 3ft swell is small, and the wind is still cross-on. The energy levels fall to moderate, around 887 to 2569. Thursday the 27th afternoon sees a spike in energy to 2197, but again, the conditions are poor. There’s just no window of clean, offshore wind with decent swell.

Honestly, if you’re looking to paddle, this is a blank run. The setup here might actually be more interesting for kite surfing than paddle surfing on most days, given the consistent cross-on wind and solid swell. It’s a quiet outlook, but forecasts can always change, so keep an eye on it.

Rusty.
