The Lowdown
Hey gang, Rusty here. Let’s talk about what’s in the water for the next couple of weeks. We’ve got a solid stretch ahead, so here’s the lowdown.
Icelands is a reef break, for advanced surfers only, and it’s fairly consistent. The water temp is 30°, which is pretty normal for this time of year.
The action starts on Friday, the 4th of September. With a clean cross-off breeze, we’ve got a 4ft swell from the SSW. The energy is moderate (573). It’s a decent opener. Friday afternoon and Saturday morning keep that size, but by Saturday afternoon the wind picks up to a fresh breeze, and the energy jumps to strong (1103). It’s a bit on the messy side for the morning.
Sunday the 6th and Monday the 7th have some storm risk and moderate breezes, keeping conditions just okay even though the swell holds at 3ft to 4ft. The energy stays moderate to strong.
Now for the good stuff. From Tuesday, the 8th of September, things get serious. That morning we see a super long-period 20-second swell from the south, but it’s small at 3ft. The real standout is Tuesday afternoon. It’s a 4ft SSW groundswell with a 17-second period and strong energy (1390). Under a gentle breeze, it’s clean, powerful, and built for experienced surfers. Wednesday the 9th and Thursday the 10th keep that quality rolling with 5ft and 5ft SSW swells and light winds.
The absolute peak runs from Friday the 11th through Saturday the 12th of September. Friday morning is a solid 5ft of SSW swell, a 15-second period, and very strong energy (1408) with a light breeze. Saturday the 12th morning? That’s the big one. A 4ft SSW swell with a 20-second period and a massive 2018 combined energy. That is serious, powerful groundswell for this reef – a heavy, long-period groundswell that will work best on a point setup. Experts only.
From the 13th into the 14th of September, the swell kicks up to 7ft. The energy is enormous (3221), but the wind gets stronger. The morning of Monday the 14th is a special one though – glassy conditions from the east with a 6ft SW swell. That’s perfect, clean conditions for the advanced crew. The 15th and 16th of September bring some more glassy mornings with 6ft and 5ft swell.
The second week eases off a bit, with some lumpy days from the 17th to the 19th as the wind shifts. However, the 18th (Friday) afternoon is flat-out good: glassy, 6ft SSW swell with a 17-second period and strong energy (1751). And the 19th (Saturday) morning has offshore ESE winds on a 5ft SSW swell – a clean, beautiful way to wrap it up.
Bottom line: this reef is a goer. The best bets are Friday 11th morning and Saturday 12th morning for raw power, and Monday 14th morning for that glassy perfection. It’s for the big boys, so if you’re not confident, sit it 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.
