The Lowdown
Right then, let’s have a look at what’s on the cards for Icelands. This is a reef set-up that takes a south-southwest swell best, and it’s a spot for the experienced crew – it’s fairly consistent but can get crowded. Water temps are about what you’d expect for this time of year, nothing out of the ordinary.
We’ve got a bit of a slow start, but things kick off on Saturday, August 15th. The morning sees a solid 5 ft swell from the south, with a 14-second period, and a cross-off breeze from the southeast. The energy’s pumping with a reading of 1461, so it’s proper moderate to strong. It’s a clean session, but it’s one for the advanced surfers only. The afternoon drops off a touch to 4 ft and goes cross, less appealing.
Sunday, August 16th, is a real gem. The morning is glassy – that’s a 3 mph glass-off from the SSE – with 4 ft of south swell at a long 15 seconds. The energy is solid at 926. That’s clean, inviting, and the best of the early window. The afternoon stays glassy with a touch less size.
Monday, the 17th, stays clean with cross-off winds and 4 ft of south swell, but the energy drops a bit. It’s still good, but not the standout.
Now, the real standout is Wednesday, August 19th. The morning is pumping: 8 ft of south-southwest swell at an 18-second period, with a clean cross-off from the SSE. The energy is massive at 3836 – that’s proper strong. This is a morning for the experts only, it’s big, powerful, and clean. The afternoon gets a bit cross-choppy, so hit the early bird.
Thursday, the 20th, keeps the size up at 8 ft and 16 seconds, with clean cross-off winds in the morning. Energy is still huge at 2957. Another top session for the experienced.
The week after, from the 22nd onwards, we see a steady drop in size but the quality holds. The 22nd and 23rd keep offering clean cross-off winds with 5 ft to 7 ft of south-southwest swell, energy still strong. From the 24th, there’s a risk of thunderstorms, but the swell stays clean, around 3 ft to 4 ft, and the period stretches out. It’s still good, just smaller.
The final standout is at the end of the run. On Friday, August 28th, the afternoon goes glassy with 5 ft of south-west swell at an 18-second period, and energy shoots up to 2150. Then Saturday, August 29th, both sessions are absolute magic: glassy or offshore winds, 7 ft of south-west swell at 17-18 seconds, and energy at 2668 and 2599. That’s a long-range call, but it looks bloody promising.
So, to wrap it up: the best of the best is Wednesday, August 19th morning, for the big, powerful, clean swell. Then keep an eye on that Saturday, August 29th, for a potential late-season gem. Crowds are likely at this spot, especially on the good days.

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.
