The Lowdown
Mate, let’s have a good hard look at the charts for Icelands. It's a reef break with a solid SSW direction that lines up perfectly with what this place loves, and over the next couple of weeks we’ve got a proper run of swell to work with. The water temp is sitting about average for this time of year, nothing wild, so you won't need a thick steamer unless you run cold.
We’ve got a bit of a slow start on Tuesday the 18th with swell around 6ft and 6ft but the wind is cross-off and the waves are clean, just a bit marginal with the tide and energy sitting at 2237 and 2754 – moderate to strong energy. Nothing to rush out for.
Then Wednesday the 19th morning is where it starts to get interesting. The swell jumps to 8ft from the SSW with a very long 18-second period, putting combined energy at 3838 – that's strong. The wind is light and cross-off, and the conditions are clean. This is proper groundswell, and for a reef like Icelands, the long period means the waves will have real shape and power, with decent gaps between sets. That size is for experienced surfers only – if you're a beginner, stay on the beach. Crowds are often a thing here, so be ready to share.
The standout window starts on Thursday the 20th morning. We’ve still got 8ft from the SSW, period a solid 16 seconds, and clean conditions with a light cross-off breeze. Energy is 3105 – strong. This is the one to pencil in. The direction is right on the optimum, the wind is sweet, and the reef will handle it beautifully.
Friday the 21st holds clean 6ft in the morning, still with strong energy (2130), but by Saturday the 22nd and Sunday the 23rd the swell drops a bit and the wind picks up slightly, turning the afternoon sessions a little lumpy. Still clean mornings though, with swell between 6ft and 7ft.
We get a quieter spell from Monday the 24th through to Thursday the 28th. The swell drops under 5ft, energy falls into the weak to moderate range (around 665 to 1488), but the mornings stay clean. Fun little waves for a longboard or a fish, nothing to get emotional over.
Then you’ve got a late push starting Friday the 29th morning. Swell builds to 5ft from the SW, period 18 seconds, energy climbs to 1779. By Saturday the 30th morning it jumps to 6ft from the SW, period 16 seconds, and we get glassy conditions – that’s a rare treat. Energy is strong at 2109. Sunday the 31st morning holds 6ft from the SW, clean with light cross-off wind, energy 3329 – that’s a serious standout for the second week. Then Monday the 1st September morning delivers 8ft from the SSW, period 17 seconds, clean, with energy 3194. Tuesday the 2nd September morning is also 8ft from the SSW but with a bit of cross-on wind – still worth a look.
So to wrap it up: the absolute best on offer is Thursday the 20th morning and Sunday the 31st morning. The first one is more certain, the second week swell is promising but less locked in. Both have the size, direction, and clean winds to make Icelands fire. If you’re a strong surfer, don’t miss Thursday. If you want to gamble on a glassy day with a solid swell, Sunday the 31st could be the sneaky winner.

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.
