The Lowdown
G’day, Rusty here. We’ve got a solid 16-day stretch ahead for Icelands, a reef setup that’s exposed to the south-southwest, and that’s exactly where the energy’s coming from. It’s an advanced wave, fairly consistent, but let’s break down the real story.
The pattern kicks off with a bang. Saturday the 12th sees some solid, long-period groundswell—6 ft of SW swell at 19 seconds, packing a beefy 3086 units of energy. It’s a proper swell, but the wind is a cross-shore S at 9 mph, so the surface is a touch lumpy. Water temp’s sitting at 84°, which is about average for this time of year, so nothing weird there. The wave comment says marginal, but that’s more about tide than the swell itself. Sunday the 13th holds similar size—7 ft in the morning—but the wind jumps to 16 mph and there’s thunderstorm risk, so it’s a bit wild.
Now, here’s the standout: Tuesday morning, the 15th of September. We’ve got 6 ft of SSW swell at 15 seconds, clean cross-off SE wind at 9 mph, and the comment says excellent for experienced surfers. That’s your window for a proper session. The energy is moderate at 1250 units, but the combo of size, direction matching the optimum (SSW), and clean conditions makes it the pick of the first week. Just watch for the crowd—this spot is often busy, so get in early.
The swell ticks down mid-week but hangs around 5 ft to 4 ft through Thursday and Friday the 17th and 18th. The wind stays cross-off, mostly clean, but the energy drops into the 900-1000 range. It’s still surfable, just not as punchy.
Then we hit a second pulse. Sunday the 20th afternoon brings 6 ft of SSW swell at 15 seconds, with light cross-off wind at 6 mph—clean and glassy conditions, and the comment says excellent for experienced surfers again. That’s your other standout. A solid, long groundswell (15 seconds) paired with light breeze, and the energy is moderate at 1739 units. It’ll be a glorious afternoon if you can sneak out.
From Monday the 21st through Wednesday the 23rd, we see a run of clean mornings with 5 ft to 5 ft swell and very light winds, including a glassy morning on Wednesday the 23rd. The energy hovers around 1000-1400—nothing huge, but clean and smooth for a reef that likes a bit of push.
There’s a lull on Thursday the 24th with only 3 ft, but Friday the 25th ramps back up to 6 ft-6 ft with a very long-period 18 seconds. That’s a classic groundswell, but the wind is moderate and cross-off or light cross, so the wave might break a bit straight at times. Still, the energy shoots up to 2028 units on Friday morning—strong enough to get the heart going.
The final weekend, Saturday 26th and Sunday 27th, serves up clean 5 ft to 6 ft SSW swell with light cross-off winds. The energy is around 1200-1400, and the comment for several sessions says excellent for experienced surfers. A consistent, clean end to the outlook.
Overall, the best windows are Tuesday morning the 15th and Sunday afternoon the 20th. Both offer a true standout combo of size, period, and clean wind. Don’t sleep on Wednesday morning the 23rd either—glassy, 5 ft, and the reef will be doing its thing.
Stay salty, catch you in the water.

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.
