The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Icelands over the next couple of weeks.
We’ve got a solid run of swell ahead, and the long-period groundswell from the SSW is the main story. This is a reef break, exposed to that direction, so it lines up perfectly. The water temp is about average for this time of year, so nothing unusual there.
The action kicks off Wednesday the 19th of August with a serious 8ft SSW swell carrying a very long period of 18 seconds. The energy is massive (3797). This is expert territory only at that size, but it’s clean and the wind is a light cross-offshore breeze. Thursday the 20th is a real standout. Thursday morning delivers a 8ft SSW swell (16s period, 3051 energy) with a cross-offshore breeze. Then Thursday afternoon goes glassy – that’s right, glass. A 8ft SSW swell with zero wind. That’s as good as it gets. The crowd factor here is “often,” so you’ll want to be early.
Friday the 21st eases a touch to 6ft, still clean and cross-off, but the real highlight of the first week is that glassy Thursday afternoon session.
Saturday and Sunday the 22nd-23rd see the swell dropping but the wind turns gusty and there’s a risk of thunderstorms. The energy drops, but it’s still clean. By Monday the 24th the swell bottoms out around 4ft from the S, but it’s still a clean morning.
The second week is less certain, but worth watching. Around Thursday the 27th a new long-period SSW swell fills in again, 5ft with 17 seconds (1639 energy), and the wind is light and cross-off. Friday the 28th holds 5ft and Saturday the 29th is smaller but clean. Then we head into early September, and on Monday the 31st of August and Tuesday the 1st of September we get another pulse. Tuesday the 1st of September afternoon is a standout: 8ft SSW at 16 seconds, clean, light breeze, excellent conditions for experienced surfers (3084 energy). That’s a serious session if the forecast holds.
The best of the whole outlook? Thursday the 20th of August afternoon with glassy conditions on a solid 8ft SSW groundswell. And the early September window (around the 1st) looks promising for another big, clean day.
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.
