The Lowdown
Alright folks, Rusty here. Let’s look at what Icelands (reef) has on offer over the next couple of weeks. The water temp is about 85°, which is normal for this time of year, so nothing wild there.
We’re kicking off with a bit of a slow start. Friday morning the 21st has a 6ft SSW groundswell with a long 15-second period and moderate combined swell energy (2279), but the wind is a cross-off from the SE, so it’s clean. That’s the only session worth a look for the first few days. Friday afternoon gets a cross-chop, and Saturday through Monday are all rated as marginal, despite some clean windows. The swell is there, in the 5ft to 7ft range, but the scores are low, so it’s not really singing.
Tuesday the 25th is where things perk up. Morning has 6ft SSW at 15 seconds, combined energy of 1225 (moderate), and light cross-off winds making it clean. Excellent conditions for experienced surfers. That pattern holds through to Tuesday afternoon (5ft, clean), and Wednesday the 26th morning is still good with 5ft and light winds. But we get a few days of smaller, less exciting surf before the next real standout.
Now, Thursday the 27th is a gem. Morning offers 3ft of 19-second SSW groundswell with 1335 combined energy. That’s a super long period, making it a proper groundswell – great for this reef setup. Winds are light and cross-off, so it’ll be glassy. And then the afternoon hits 5ft at 18 seconds with 1733 energy – still clean and excellent. Crowds are “often” here, so expect some company at this reef.
The next big highlight is Monday the 31st. Morning shows 4ft SW at 18 seconds with 1117 energy, but the wind is glassy from the ESE – just about perfect conditions. Afternoon bumps to 5ft SW at 18 seconds (1535 energy) and stays glassy. This is about as clean as it gets for a reef break.
But the absolute best on offer? That’s Tuesday the 1st of September. Morning has 8ft SSW at 18 seconds, combined energy of 3464 (strong), with light cross-off winds. Afternoon hits 8ft at 18 seconds with 3663 energy – that is serious, powerful swell. Winds are light and cross-off. This is big, clean, powerful reef surf with excellent conditions. It’s for experts only – anything over 8ft on a reef like Icelands is no joke. This is the standout of the whole run, though being more than a week out, it’s promising but not locked in yet.
After that, Wednesday the 2nd still has 7ft SSW (16 seconds, 2573 energy) with clean morning conditions, but the afternoon gets a light cross-chop. The rest of the run into early September sees size drop, but clean windows pop up again on Thursday the 3rd and Saturday the 5th, with 5ft and 5ft SSW swells and clean winds. The very end of the forecast on September 5th afternoon shows some cross-shore ripple, but it’s still workable.
Overall, Icelands is fairly consistent through this run. There are a few days with marginal calls, but the persistent swell and clean morning winds mean it rarely goes flat. Just remember, for beginners, anything over 5ft might be too heavy here, and that Tuesday September 1st is expert territory.

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.
