The Lowdown
Alright, Rusty here, switching to feet and miles for the crew that thinks that way. For Icelands, a reef break that loves a south-southwest swell, the water temp is about normal for the season. The first half of the week has some surf, but you've got to wait for the good stuff.
The first real standout is on Friday, August 14th. We're looking at a solid 6.6ft swell from the south, with a very long period of 15 seconds. The wave energy is strong, and the wind is glassy in the afternoon. That's a recipe for perfection. The swell direction is ideal for the break, and with that long period, it's a proper groundswell. This is for experienced surfers, and expect a crowd.
The next big one is Wednesday, August 19th. The morning has a 7.9ft SSW swell with an 18-second period, and the energy is pumping. The afternoon gets even better at 8.2ft with a 17-second period. The wind is a clean cross-off all day. This is big, powerful, groundswell, and for a reef, it's the pick of the whole 16-day forecast. It's expert-only territory, but it will be worth the paddle out. Expect it to be busy.

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.
