The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the cards for Icelands.
Right off the bat, we’ve got a solid pulse of SSW groundswell rolling in on Monday the 20th of July. The morning session sees a clean 5.6 ft wave with a super long 17-second period, and the combined energy is pumping at 1688 (strong energy). The wind is light and offshore from the ESE, so the reef break is looking clean and powerful. This is proper, expert-level stuff – not one for the beginners. The water temp is about average for the time of year, so no surprises there.
The surf drops off pretty quickly after that initial pulse. The swell backs down through the rest of the week, with the wind staying mostly cross-off from the SE, which keeps the surface tidy but the waves lose their grunt. Periods drop into the 10-14 second range, and the energy fades into the low hundreds. There’s a brief uptick on Thursday afternoon the 23rd with a 5.2 ft S swell, but the period is a short 10 seconds, so it’s not going to have the same shape or punch as the Monday morning.
We then hit a quiet stretch from the end of July into the first week of August. The swell is small, mostly under 3.3 ft, and the energy is weak. But hold on – the real standout is shaping up from Thursday the 30th of July. It starts to build again, with a 2.3 ft, 19-second groundswell on Thursday morning, and the energy jumps to 617 (moderate). The winds go glassy, which is a dream.
Then Friday the 31st of July and into the weekend look absolutely firing. We’re talking about a 3.9 ft to 5.2 ft SW swell, with periods holding at 15-17 seconds, and the energy is strong (over 1000). The wind is glassy or near-calm, the conditions are clean, and the break is exposed to the SSW swell direction, which matches the optimum. This is the best on offer – a true window of world-class conditions for the experienced crew. It’s a long-range call, so stay hopeful, but the signs are all there.

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.
