The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Icelands.
We’ve got a solid run of surf coming up, kicking off this Saturday and running right through the 16-day window without any real gaps. This is a reef break, so it handles a variety of conditions, and it’s exposed to the SSW swell that’s going to be feeding in.
The standout action starts this Saturday, September 12th. The morning session has a clean 5ft SW swell, and that wind is light offshore from the east. The wave energy is pumping (2103), and it’s a long-period groundswell of 19 seconds. This is expert territory due to the reef, but the conditions are excellent. Saturday afternoon gets even better with a 6ft SW swell (3058 energy) and glassy cross-offshore winds. That’s your top pick for the whole period.
Sunday the 13th sees the swell bump up to 7ft, which is getting substantial. It’s still a solid SW groundswell (2370 energy), but the wind picks up from the southeast at 12 mph. It stays cross-offshore and clean, though the wind strength and size make it one for the experienced crew only. The quality dips a bit through Monday and Tuesday morning before another excellent window on Tuesday, September 15th morning. That’s a 6ft SSW swell (1256 energy) with clean cross-offshore winds again.
Moving into the second week, the pattern holds but the swell sizes drop back. September 20th (Sunday) morning offers a clean 6ft SSW swell (1570 energy) with light winds, and the afternoon pushes back up to 7ft (1970 energy). That Sunday afternoon is a serious highlight for the later part of the forecast.
For the very end of the run, September 23rd Wednesday morning gives us a clean 5ft SSW groundswell (1229 energy) and light offshore winds. There’s even a glassy morning on September 24th with a tiny 3ft SSW swell – clean but small.
A note on the water: it’s about average for this time of year, so no surprises there.
Overall, the best of the best is Saturday September 12th, particularly the afternoon session with that 6ft SW groundswell and silky cross-offshore breeze. That’s the one to circle. The Sunday the 20th afternoon is your runner-up for the second week. This break can get crowded, so expect plenty of company on the peak.
Stay safe out there.
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.
