The Lowdown
Alright, Rusty here. Let’s talk about the surf coming up at Icelands.
The pattern kicks off on Monday the 10th of August with a solid pulse of south swell, but conditions are a bit messy with a cross-shore wind and some chop making it less than ideal. The water’s a warm 85°, which is about what you’d expect for this time of year.
The real standout window starts to shape up by Tuesday morning, August 11th. You’ve got a clean 7ft south swell with a 17-second period, which is proper groundswell, and cross-offshore winds from the southeast making for some clean faces. The wave energy is strong at 3531, so there’s plenty of power. This sets up nicely for the advanced crew here.
Wednesday the 12th keeps the good vibes rolling with clean 6ft to 7ft south swell and light cross-off winds. The energy is still solid at around 1795 to 1979. Then Friday morning, August 14th, is a real gem – 7ft south swell and glassy conditions with east-northeast wind at just 3 mph. That’s about as clean as it gets.
Heading into the second week, the swell backs off a bit but stays rideable. By Friday the 21st of August, we see another spike: an 8ft SSW swell with a 17-second period, combined energy hitting 4107, and clean cross-off winds. That’s big, powerful, and one for experienced surfers only – too much for any beginner.
The best day overall? Friday the 21st offers the biggest, most powerful swell of the window, but the cleanest, glassiest morning is Friday the 14th. Take your pick.
This is a reef break with consistent, exposed south-facing swell. The optimum direction is south-southwest, so that SSW swell on the 21st lines up perfectly. Crowds are often here, so expect company on the good days.
Signing off,
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.
