The Lowdown
G’day, I’m Rusty. Let’s talk about what’s shaping up for Icelands.
Alright, we’ve got some swell coming through, but the first week is a bit of a mixed bag. Wednesday morning the 16th starts with 1.5m of SSW swell at 14 seconds, with a moderate cross-off wind from the SE at 25 km/h. It’s clean, but conditions are marginal, and the combined energy is moderate at 997. Not worth rushing out for. The water temp is about average for this time of year. Thursday the 17th is similar with 1.6m SSW swell, clean wind from the SSE at 20 km/h, but the energy is 1020 and things are still borderline.
Friday the 18th sees the swell drop to 1.3m with a cross-shore breeze, so it weakens. Saturday the 19th brings a bump to 1.7m of long-period SSW swell at 18 seconds, energy at 1680, and clean cross-off winds in the morning. There’s a risk of thunderstorms, but it’s not a standout. Sunday the 20th has 1.9m SSW swell, 16 seconds, and clean winds—energy 1727, still tagged as marginal.
The first real gem appears on Monday the 21st. That morning, we’ve got 1.8m of SSW swell at 14 seconds, with a light cross-off breeze from the SE at 10 km/h. It’s clean, with 1325 energy, and the wave comment says “excellent surf conditions for experienced surfers.” But Monday afternoon is the real winner: dead calm, glassy conditions with 1.7m swell and 1110 energy. That’s the best of the first week—clean, glassy, solid shoulder-high waves for the experienced crew. This is a reef break, so the long-period groundswell (14 seconds) will wrap in well. Crowds are possible here.
Tuesday the 22nd is still okay with 1.4m swell and clean winds in the morning, then a 1.1m swell with an 18-second period in the afternoon—clean but smaller.
Wednesday the 23rd is another good one: 1.9m SSW swell, 16 seconds, energy at 1989, and clean cross-off winds in the morning with a risk of storms. Marked as excellent for experienced surfers.
After that, the swell drops off for a few days. Thursday the 24th and Friday the 25th only have 1.1m surf, with energy around 575 to 638. It’s clean but weak, so there’s a gap.
Then things ramp up again on Saturday the 26th. The morning has 1.8m of very long-period SSW swell at 20 seconds, with energy at 3587 (strong!). The wind is a gentle cross-off from the SE at 15 km/h, and it’s clean. Saturday afternoon jumps to 2.4m at 19 seconds, energy at 4084 (very strong!). This is big, powerful groundswell—only for experts as it’s over 2.5m. Sunday the 27th keeps it going with 2.4m in the morning and 2.3m in the afternoon, both clean. The afternoon is tagged as excellent for experienced surfers, with energy at 3114. This is the second standout: big, heavy, and too much for most.
Monday the 28th drops to 1.8m, then it fades into the start of October. The 30th of September and the 1st of October have some glassy moments with 1.5m swell, but nothing like the earlier days.
The best options are Monday the 21st afternoon for glassy conditions, and the 26th and 27th for the bigger groundswell. The second week is looking promising but it’s a ways out.
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.
