The Lowdown
Alright mates, Rusty here. Let’s break down the forecast for Icelands (reef break). The water’s about 85°, which is pretty normal for the season.
The first real action worth paddling out for is Thursday the 13th in the morning. We’re looking at 6ft swell from the S, a 14-second period, and cross-offshore winds from the SSE. That’s clean, with moderate wave energy (1716). Made for the experienced surfer. Thursday afternoon drops a little, but Friday the 14th afternoon is the early winner. Glassy conditions, zero wind, and a solid 7ft of S swell with a 15-second period. That’s a clean, powerful setup (2010 energy).
Saturday morning the 15th keeps it clean: 5ft, offshore E winds, and strong energy (1461). Then we get a few days of smaller, but still clean, surf with cross-off winds.
Jump ahead to the 18th of August. Tuesday morning brings 6ft of SSW swell, 16-second period, and cross-off winds from the ESE. Good energy (2004). But Tuesday afternoon is a gem: 5ft might not look big, but with a 19-second period and a massive 2670 energy rating, this is a groundswell that will be wrapping around the reef beautifully. Winds are cross-off from the SE.
The 19th of August sees the swell jump. Wednesday morning has 8ft of SSW swell, 18-second period, and cross-off winds – clean, but the energy is huge (3326). That’s for experts only. Wednesday afternoon goes to 8ft, but a cross wind from the S at 12 mph puts a chop on it.
The absolute best window is Thursday the 20th of August. Morning session: 8ft of SSW swell, 16-second period, cross-off winds from the SE, and an energy reading of 3205. Clean and powerful. That’s the one to chase.
The following week stays strong. The 22nd of August (Saturday) has a 6ft SSW swell with offshore ESE winds in the morning, and the afternoon goes glassy. Sunday the 23rd is also glassy all day with 5-5ft waves.
The 24th of August (Monday) brings a 4ft S swell with a very long 19-second period and glassy conditions. That’s a dream for a longboard, with moderate energy (1436).
The 25th of August has a late afternoon treat: 3ft might be small, but with a 20-second period and glassy conditions, it’s a clean, long-period groundswell for the skilled.
Finally, the 26th of August (Wednesday) morning delivers 7ft of SSW swell, 17-second period, and glassy winds. Energy is strong (2625). Another one for the experienced crew.
Crowds are often at Icelands, so expect some company. The optimum swell direction is SSW, and we’re getting plenty of that.
The top picks are Friday the 14th afternoon for the glassy 7ft, and Thursday the 20th morning for the powerful 8ft with clean winds. Get after it.
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.
