The Lowdown
Rusty here again, looking at the same stretch but in feet and Fahrenheit.
Alright, so for Inside Reef (Hikkaduwa), it’s a pretty grim run. Every single session over the next 16 days is flagged as “poor surf conditions.” Nothing to get amped about.
Starting Sunday, the 23rd of August, you’ve got a 5ft swell from the S, but the wind is blowing 16 mph from the WSW, right onshore, and there’s a risk of thunderstorms. Combined swell energy is strong at 1302, but it doesn’t matter when it’s all blown out. Water temp is 83°, which is pretty normal for this time of year.
The rest of that first week keeps the same story. Tuesday the 25th and Thursday the 27th bring the biggest swells, 5ft to 7ft from the SSW. That Thursday morning is a monster – 7ft, with a very long 19-second period and combined energy of 3126. That’s serious groundswell for a reef break. But again, the onshore wind from the WSW at 16 mph ruins the surface.
Crowds are “sometimes” possible, but with these conditions, you won’t be fighting for waves. No standout session in the first week.
Into the second week, from the 31st of August through the 4th of September, swell hangs in the 5ft to 7ft range from the SSW. The 31st has a 7ft SSW swell with 18-second periods and energy of 2920 – plenty of power. But the wind stays onshore. If it ever swung to the optimum ENE, this would be epic, but it doesn’t.
By the 5th and 6th of September, swell drops to 4ft, period shortens to 10–11 seconds, and energy falls below 800. Even with a clearer sky on the 5th afternoon, the wind is still cross-onshore.
No standout across the whole 16 days. If you’re really keen, Thursday the 27th morning has the biggest, longest swell, but expect a choppy mess. Honestly, with this steady onshore wind and solid swell, it looks better for kiting than surfing.
Keep an eye on it, forecasts can shift.
