The Lowdown
Righto, grab ya coffee. Rusty here.
Alright, so Icelands is where it’s at for the next couple of weeks. It’s a reef setup, exposed to the south-southwest, so it’s gonna pick up a nice consistent run of groundswell. The water’s sitting at 85.3°, which is about normal for this time of year. First real standout is Wednesday, August 19th. That morning we’re looking at a solid 8.2ft of SSW groundswell, period stretching out to 18 seconds – proper long-period energy with bags of punch. The wind is a gentle cross-offshore breeze, so the face will be clean as a whistle. The combined energy readings are through the roof (3833), so you’re talking powerful, well-shaped waves. This is advanced territory though – 8.2ft with that length of period will be a handful for anyone without experience.
Thursday 20th isn’t far behind. Morning sees 7.9ft from the same SSW direction, with a 16-second period and a light cross-offshore breeze. The combined swell energy is still huge (3065). The afternoon looks even cleaner with the wind dropping to a light breeze and the waves holding at 7.5ft. This is your pick for a proper session if Wednesday feels a bit too rowdy.
We’ve got a solid run through the end of the first week. Friday 21st is a bit less consistent with 5.9ft, and Saturday 22nd bumps back up to 6.9ft but the wind is a moderate cross-off. There’s a brief dip early the following week.
Now, look ahead to the end of the month. Sunday 30th August morning has a good 4.9ft swell with 16-second period and light wind. That’s a solid wave.
But the true standout for the second week – and this is a long-range promise – is Monday, 31st August morning. We’re looking at a 6.6ft SSW swell pumping in with a 19-second period. That is some very long period groundswell. The combined energy is a massive 3718, and the wind is a light offshore breeze from the east-southeast. The waves will be big, clean, and powerful, with long lulls between sets. Ideal for the reef at Icelands but will be pushing well over 6.6ft at its peak, so it’s one for the experienced crew only. Crowds can be an issue here – it’s a known spot – so get there early for that one.
Don’t sleep on Tuesday 1st September either. Morning has 7.2ft from the SSW with a 17-second period and light offshore wind. Another excellent session for the experts.

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.
