The Lowdown
Alright, Rusty here. Let’s get into it. We’ve got a solid 16-day window ahead, and after a slow start, it really cranks.
The first few days are a bit of a write-off. Sunday the 19th is a no-go with that risky stormy vibe and cross-onshore wind making a mess of things. The real action kicks off Monday morning the 20th. The swell builds nicely from the SSW, coming in at 6 ft with a long 17-second period and light offshore E wind. That’s clean, powerful, and has some serious juice. The combined energy is a beefy 1677 (strong), so you’re looking at proper groundswell. This is a reef break, so that low period is perfect for it – expect well-shaped lines and longer sets. The water temp is about average for this time of year, so nothing unusual there. This is for the advanced crew, though; 6 ft with that energy is no joke for beginners.
The standouts are Monday the 20th and Tuesday the 21st. Monday morning is glassy and clean, and Monday afternoon goes fully glassy with a light S breeze. Tuesday the 21st keeps it going with 5 ft SSW swell, 14-second period, and clean cross-offshore winds from the SE. The energy is still moderate to strong at 956, and the conditions are very good. Wednesday the 22nd drops a little in size but stays clean.
After that, we hit a bit of a lull from Thursday the 23rd through to Sunday the 27th. The swell direction shifts to SSE, and the period drops to 10-11 seconds, so it’s a bit weaker and more jumbled. Winds are cross-offshore but stronger, pushing 12-15 mph, which makes it marginal. The energy sits in the 600-700 range (moderate), but the quality drops. Kite surfers might find it more interesting than paddle surfers on those days.
Monday the 28th and Tuesday the 29th see a small rebound, with glassy conditions early on Monday and a clean 2 ft-3 ft SSW swell coming through. The period jumps back to 15-16 seconds, so it’s a long period groundswell, but smaller. The energy is moderate at 387-469. Still, a glassy morning on a reef with a long period is a good time.
Now, the real fire is in the second week. Hold onto your boards. Thursday the 30th of July brings a massive 19-second period SSW swell of 4 ft, but the energy is already strong at 1308. The real standout, though, is the first weekend of August. Saturday the 1st of August fires up with 6 ft to 7 ft SSW swell, a 16-17 second period, and clean cross-offshore winds. The energy is a very strong 2309-2330. This is expert territory, pure and simple. The reef is going to be firing with thick, powerful lines. Sunday the 2nd follows with 6 ft, 15-second period, and glassy conditions in the afternoon. That’s a dream session. It’s a long-range call, so it’s promising but keep an eye on it. Monday the 3rd holds strong at 6 ft with a 16-second period and clean conditions.
The best of the whole window is without a doubt Saturday the 1st of August at Icelands. The combination of that solid 7 ft SSW swell, 16-second period, and clean cross-offshore wind is going to produce some world-class waves. Crowds are likely here, so get in early.
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.
