The Lowdown
Rusty here, taking a look at the same window but in feet.
Alright, we’re starting at Icelands, a reef that breaks fairly consistently, soaking up south-west swells. Water temp is about what you’d expect for this time of year.
So, kicking off Tuesday the 11th of August, we’ve got a solid pulse running – around 7 to 8ft from the south, with a real long 17-second period. That’s some serious groundswell energy (3539), but the wind is a cross-offshore, which isn’t ideal for a reef. It’s looking a bit marginal, and with that long period, the sets will be fat and maybe a bit walled. Not the best for beginners, and even for the experienced crew, it’s a bit of a coin flip. Wednesday the 12th is more of the same, the swell drops a touch, wind turns cross-shore, and you’ve got a light chop.
Thursday the 13th is where we start to see some quality. Morning swell is about 6ft, clean with a cross-off breeze. Period is 14 seconds, which will help the shape. The afternoon is a real treat – 5ft but with a very long 19-second period, clean as a whistle. That’s the kind of glassy, long-period groundswell that a reef loves. This is for the experienced surfer. Friday morning the 14th brings a bigger push – 7ft with a 16-second period and clean conditions. That’s a standout morning, but the afternoon gets choppy.
But the true gem is Saturday the 15th and Sunday the 16th. Saturday morning we’ve got 5ft from the south, light offshore wind (barely 3 mph), and clean conditions. That afternoon goes glassy with 5ft – absolutely perfect, glassy reef surf. Sunday is even smaller, 4ft, but the wind is glassy all day. That’s the cleanest window in the whole run. It’s not huge, but it’s gorgeous.
After that, we get a lull on Monday the 17th, then a run of bigger but messier conditions from Tuesday the 18th through the weekend. The swell gets back up, 6ft to 8ft, but the wind is a constant cross-off or cross-shore, and the forecast keeps saying marginal. There are clean morning windows, like Friday the 21st with 8ft and a 17-second period, but the wind is moderate. The energy is high (3139), but it’s not as good as glassy.
Looking at the final stretch, Monday the 24th and Tuesday the 25th look promising again. Monday afternoon is clean, 6ft with light wind, and Tuesday morning is even cleaner, 5ft with light wind. Then Wednesday the 26th morning brings a 6ft south-west swell with a long 18-second period and light cross-off wind – a nice, clean, punchy wave for the experienced guys.
The standout is without question Saturday the 15th and Sunday the 16th. Glassy conditions, clean 4ft to 5ft south swell – that’s a reef’s best friend. Thursday the 13th afternoon is a close second with that long period and clean wind. The first week has the best quality; the second week is more mixed but has a few clean windows. Keep an eye on the 24th and 25th.

Information about the Icelands Surf forecast
The above surf forecast table for Icelands provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Icelands can be found by selecting the local surf guide option on the grey menu. Our Icelands surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Icelands) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Icelands may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
