The Lowdown
Alright, Rusty here, let’s talk about what’s cookin’ at Icelands. This is a reef set-up, exposed to a south-southwest swell direction, and it’s got a solid run of surf lined up. The water’s sittin' at about 85°F right now, and that’s bang on average for this time of year, so no crazy warm or cool surprises.
The first real action kicks off Tuesday morning, the 25th of August. The swell is already a clean 5ft from the SSW, with a very long 15-second period pushing some serious energy into the reef (1067). The wind is a light cross-offshore breeze out of the SE, and the conditions are labelled as clean and excellent for experienced surfers. This is your classic reef setup – that long period means the waves will have plenty of shape and power, but it’s gonna be a bit too much for beginners at this size. Get out there early for the best of it.
The pattern holds through the week. Wednesday morning, the 26th sees the swell drop a touch to 4ft, but the wind goes glassy with a 3 mph offshore from the E. That’s about as perfect as it gets for a clean face. The energy is still moderate (684), and it’s another day for experienced surfers looking for a smooth ride.
Now, the standout window really starts to build. Thursday the 27th into Friday the 28th is where I’d circle on the calendar. Thursday morning has a 4ft swell with a ridiculously long 19-second period, blasting in at a very strong combined energy of 1701. The wind is cross-offshore and light. By Thursday afternoon, the swell jumps to 6ft with an 18-second period and energy topping 2104 – this is proper, powerful SSW groundswell. This is advanced territory, with waves that have serious punch and length. Friday keeps that energy going with 6ft swell in the morning and clean cross-off winds. This is the heart of the run.
Things briefly back off on Saturday the 29th and Sunday the 30th. Saturday drops to 4ft with moderate energy (768) and still clean, but it’s a bit smaller. Sunday morning is even smaller at 3ft, but that 21-second period is something special – the energy is still strong (1073) and the waves will be lined up and waiting, just less push. It won’t be as consistent for a full session.
Then the second pulse hits. Monday the 31st and Tuesday the 1st of September are absolute bangers. Monday afternoon sees 6ft of SSW swell with an 18-second period and massive energy (2340), combined with glassing offshore winds. Tuesday morning is almost identical, 6ft from the SW with a 16-second period and energy of 2149. The wind stays light cross-off. This is the best of the entire forecast – powerful, clean, and consistent. It’s a dream for anyone who can handle a reef break.
Through the first week of September, the swell stays solid. Wednesday the 2nd is 5ft in the morning and 5ft in the afternoon, both with clean cross-off winds and moderate energy. Thursday the 3rd drops to 4ft, but still workable. The pattern starts to fade into the second week, with smaller days from the 5th to the 9th, though there’s a sneaky late pulse on Wednesday the 9th of September with 6ft and strong energy (1980) that looks promising, but you’re getting into long-range territory so don’t set your watch by it just yet.
Overall? This place is firing. The standouts are the 27th-28th of August for that long-period power and the 31st of August-1st of September for the biggest, cleanest surf of the run. Don’t sleep on it. The reef means it’s for the crew who know what they’re doing, and that crowd situation can get busy – so get in early.
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.
