The Lowdown
Alright, Rusty here. Let's break this down for you in feet.
We got a good stretch of surf coming for Icelands. It’s a reef break that is fairly consistent and open to SSW swells. The water’s about normal for now.
Starting out on Monday, 17 August, there’s some smaller clean waves, but it’s all about the build. Tuesday, 18 August, it starts pushing chest to head high (6ft) from the SSW, with clean cross-off winds. The energy is getting strong.
The real standout is from Wednesday, 19 August to Friday, 21 August. Wednesday morning is the absolute peak. We’re talking an 8ft swell from the SSW, with a very long 18-second period – that’s pure groundswell. For a reef, that’s going to be firing. The energy is massive (3833). That size (over 8ft) is for experienced surfers only, no question. The wind is light cross-off, so the surface is perfect. Thursday is right up there too with the same 8ft swell and cleaner, lighter winds.
The first week fades into smaller but still solid 5-6ft SSW swells with clean windows through the weekend and into the next week.
Then, looking into the second week, we get another pulse on Sunday, 30 August. You’re looking at a 6ft SSW swell, a little shorter period (17 seconds), and a bit more cross-shore wind, so not as perfect as that Wednesday peak, but still plenty of fun. The energy (2038) is still strong.
No doubt about it, Wednesday morning, 19 August, at Icelands is the one to circle. It’s the biggest, meanest, and cleanest swell of the whole stretch. If you’ve got the skills, that’s your session.
Rusty.

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.
