The Lowdown

Alright folks, Rusty here. Let’s get into it for the Hikkaduwa region.

Well, I’ll be honest with you – this 16-day window looks pretty grim for a proper paddle. We’re stuck in a pattern of persistent moderate westerly winds, which is cross-on or onshore for the majority of the run. The swell is coming in from the south to southwest, and while the periods are often long, suggesting groundswell, the wind is just wrecking what could be decent waves. The energy levels are mostly moderate, with combined energy values hovering around the 500 to 900 mark, which isn't terrible, but it's not translating to quality.

The first real hint of something worth checking out doesn't come until Monday, 20 July. That morning, the swell bumps up to 4 ft from the south with a period of 18 seconds, and the combined energy jumps to 1735 (strong energy). But the wind is still cross-on at 16 mph, and the forecast calls for "poor surf conditions." The afternoon sees a marginal shift: 4 ft from the south, 16 seconds, and energy at 1708, but still cross-on and choppy. It’s a tough call, but if you’re desperate, the afternoon might have a couple of rideable ones.

Tuesday, 21 July, is the closest thing to a standout in this whole outlook. Inside Reef itself is an advanced, exposed reef break, so it needs the right conditions. Tuesday morning we get 5 ft from the south, period of 15 seconds, with an onshore wind from the WSW at 12 mph. The combined energy is 1267. The forecast says "poor surf conditions," but the afternoon bumps up to a "marginal" call with 5 ft and 14 seconds. That’s the biggest swell we see, and the period is long enough for a point break or reef to handle it. The wind is onshore, but at that size and with a reef setup, it might be the only window for an experienced surfer to get something half-decent. The water temp is about average for this time of year, so no surprises there.

After that, the 22nd and 23rd drop back to smaller, choppier conditions. The 24th of July afternoon sees a 5 ft swell from the WNW, but with a period of only 11 seconds and cross-on wind, it’s going to be a messy, weak closeout. The energy is 1167, but that short period won't do it any favours.

The last week is more of the same: small to moderate swell from the SSW, with persistent cross-on winds and a lot of afternoon thunderstorm risks. The morning of Monday, 28 July, has a 4 ft swell from the SSW with an 18-second period and energy of 1208, but the wind is onshore from the west at 16 mph. It’s a tease – a long period groundswell that will likely just close out on the reef or be too straight to surf well.

Honestly, for a paddle surfer, this is a tough period. The 21st of July is your best bet if you’re advanced and can handle a bumpy, cross-onshore wave. For everyone else, you might want to look at other options. The wind and swell combo is honestly more interesting if you’ve got a kite – the beach and reef setup with that persistent side-shore wind could be a blast for a kite session.

Rusty.
