The Lowdown
Alright, I’m gonna switch over to the old-school numbers for the imperial crew now.
Listen up, I’m Rusty, and it’s just Icelands on the radar for this run. It’s a reef, so the advanced surfers are the ones in the conversation. Water’s about 85°, which is normal for the season.
We start Tuesday, September 8th, in the afternoon. Swell’s running 4ft from the SSW with a 17-second period. The combined energy is 1414—that’s a solid push. Wind is a cross-off from the SSE at 12 mph, keeping the surface clean. There’s a storm risk, but the waves are there.
Wednesday the 9th, the swell builds. Morning has 5ft from the SSW, 15-second period, energy 1218. Afternoon goes to 6ft from the south, still 15 seconds, energy bumps to 1572. Wind stays cross-off. It’s getting big.
Thursday morning, September 10th, is a standout. Swell is 4ft from the SSW with a 16-second period. Wind is a gentler cross-off from the SE at 9 mph. The energy is 1250, and the conditions are marked as excellent for experienced surfers. The lines will be clean and long.
Friday the 11th is similar—5ft in the morning, 5ft in the afternoon, both with 15-second periods and light cross-off winds. Good, solid days.
Saturday the 12th is a highlight. Morning: 5ft from the SW, but the period is 19 seconds. That’s groundswell with serious legs, and the energy is 2090. Wind is a gentle cross-off. Afternoon jumps to 6ft from the SW, 17-second period, and energy hits 3090. This is the big, powerful session.
Sunday the 13th holds size at 7ft in the morning, dropping to 7ft in the afternoon, both with 17 to 16-second periods. Winds are moderate cross-off. Expert territory, no doubt.
Monday the 14th is a beauty. Both sessions have 6ft from the SW, 16-second periods, and light cross-off wind. Energy is in the 1500s. Clean, powerful, and lined up.
From Tuesday the 15th to Thursday the 17th, it’s a steady diet of 5ft to 6ft from the SSW, 15-second periods. Winds are cross-off. Consistent, but not the top-tier stuff.
Friday morning, September 18th, is glassy. Wind is from the NE at 3 mph, the surface is like glass. Swell is 5ft from the SSW, 15-second period, energy 863. The forecast says very good conditions. A quiet, beautiful day.
The final week, from the 19th to the 23rd, runs 5ft to 5ft from the SSW, with periods between 14 and 18 seconds. Winds are light and cross-off. Good days for the experienced crew, but the best is the first weekend.
The two sessions to lock in are Thursday morning, September 10th for the clean, long-period perfection, and Saturday morning, September 12th for the heavy-duty 19-second groundswell under light winds.
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.
