The Lowdown
Alright, surf is finally looking like it’s waking up out there. We’ve got a solid run of southerly energy lining up for the next couple of weeks. The water’s sitting right where it should be for this time of year, so no surprises there.
We’ll kick things off this Sunday the 16th at Icelands. It’s a reef setup, so it handles this kind of swell well. Morning session is looking clean with a little chest-high set wave, around 4ft, and that light ENE cross-offshore breeze will have it looking like glass. The swell’s got some serious length to it, 15 seconds, and the energy is moderate at 926. It’s a good one to get the week started.
Monday the 17th holds similar vibes. Still clean, 4ft on the morning push with that offshore wind. The energy backs off a touch, but the conditions stay crisp. Afternoon drops off a bit in size, but it's still rideable.
Then things start to get interesting. Tuesday the 18th brings a jump in size and power. The swell bumps up to 6ft with a 16-second period, and the energy is building fast, up to 2178. It’s a bigger, stronger day, but that cross-offshore wind gets a bit feistier in the afternoon and it gets a little lumpy. This is when it starts to get more serious.
Wednesday the 19th is where it turns up a notch. We’re looking at 8ft of SSW groundswell with an 18-second period. That’s a lot of water moving. Energy is pushing into strong territory at 3846. The morning is clean, but this is expert-only territory now. It’s big and powerful, and the paddle out is going to be a mission. The afternoon gets cross-shore and chopped up, so the morning is your window if you’ve got the skill.
Thursday the 20th is a standout. The swell drops just a touch to 8ft, but the period is still a solid 16 seconds. The wind is light, the morning is clean, and the energy is strong at 3055. This is the best balance of size and quality we’ve seen so far. A morning session here will be one to remember. Friday the 21st stays good, similar size, but a bit less energy. Still a great day.
Over the weekend, we see a bit of a pulse. Saturday the 22nd has 7ft in the morning with clean conditions, but the afternoon gets crossed up. Sunday the 23rd backs off to a fun 5ft with decent 14-second period and clean morning waves.
The following week is a mixed bag. Monday the 24th has some solid 6ft waves with a long 17-second period and light winds. It’s another good morning. Then we get a bit of a lull mid-week—Tuesday the 25th and Wednesday the 26th are smaller, around 4ft and 4ft, and not as powerful. But Wednesday afternoon is interesting: the period jumps to 19 seconds on a small swell, which can do weird, fun things on a reef. Keep an eye on that.
Thursday the 27th picks back up with 6ft and the wind swings more offshore. The afternoon looks excellent with light winds, making for a clean, powerful wave.
Friday the 28th is another gem. It’s a little smaller at 5ft, but the wind goes glassy in the morning. That’s rare, so if you can get out there, it might be the cleanest wave of the whole run. The period is 15 seconds, so it’s still got shape.
The final weekend points to more solid surf. Saturday the 29th has 5ft in the afternoon with an 18-second period and clean conditions, and Sunday the 30th is back up around 6ft. The wind gets a bit stronger, but it stays offshore. It’s a promising end to the window, though mid-August long-range stuff is always a little less certain.
Overall, the standout days look like Thursday the 20th for the biggest, cleanest, most powerful waves, and Friday the 28th for that rare glassy morning session. Get on it.

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.
