The Lowdown
Right then, folks, Rusty here. Let’s have a proper look at what’s coming down the line for Icelands. This is a reef break, exposed to the swell, and it’s a fairly consistent spot that handles a good SSW groundswell. The water temp is about average for the time of year, so nothing freaky there.
We’ve got a bit of a slow start, but once it kicks off on Tuesday the 25th of August, it’s game on. The first real action is Tuesday morning with a solid 5ft SSW swell, a long 15-second period, and a light SE cross-off breeze. That’s clean, powerful, and the combined energy is pumping hard at 1067 – that’s strong wave energy. This is for experienced surfers only, though. That swell size and period on a reef means it’s not a beginner’s playground. Tuesday afternoon drops off a touch with a cross-shore wind, so the morning is the pick of that day.
Wednesday the 26th brings a glassy morning. The swell drops to 4ft, but with a 13-second period and zero wind, it’s going to be silky smooth. The energy is moderate at 688, but the quality will be high for the crew that can handle the reef. Thursday the 27th is a real standout. The morning has a 4ft, 19-second monster groundswell – that’s very long period, which on a reef like Icelands is going to produce some proper, grinding walls. The energy is 1738, which is strong. The afternoon goes even bigger with 6ft and 18-second period, energy hitting 2163. Both have cross-off winds, so it’s clean. This is the best window of the run. Friday the 28th stays solid with 7ft in the morning (energy 1913), again with cross-off winds. That’s pushing into expert territory for sure.
The weekend sees a slight dip but still fun. Saturday the 29th morning has 4ft, 14-second swell and clean conditions. Sunday the 30th is interesting – a very long 21-second period on a 3ft swell, energy 1078, with a glassy afternoon. That’s a proper, long-period groundswell that will wrap in beautifully.
The following week looks persistent. Monday the 31st of August and Tuesday the 1st of September bring the biggest swell of the whole run, with 6ft to 7ft, 16-18 seconds, and cross-off winds. The energy is through the roof, between 1952 and 2339. That’s strong to very strong, and only for the experts. Wednesday the 2nd and Thursday the 3rd of September stay solid, with glassy conditions on the 3rd afternoon. The last few days from the 4th to the 9th taper off, with smaller swell around 3ft to 5ft, but still plenty of clean conditions and glassy mornings.
The best of the best? Lock in Thursday the 27th of August. That 6ft, 18-second SSW groundswell with a cross-off breeze is the kind of day that makes a reef break sing. The 7ft days on the 28th and 1st of September are also massive, but for the perfect mix of size, power, and clean conditions, the 27th takes the crown. The 26th morning is a close second for that glassy, smooth session.
Oh, and Icelands is a reef break, and it’s often crowded, so expect company. The consistency is good, so it tends not to stay flat for long.
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.
