The Lowdown
Alright, Rusty here. Let’s talk about the next two weeks at Icelands. This is a reef break that likes the SSW swell. Water temp is about 85°F, which is just 1°F above the norm for this time of year – basically what you’d expect.
The first few days are underwhelming. Thursday and Friday (Sept 3rd & 4th) have some chest-high waves around 4 to 5 ft from the SW/SSW, but the wind is cross-off from the SE and those thunderstorm risks keep the vibe a bit skunky. Combined energy is moderate, in the high 700s to mid 800s – there’s push, but not the cleanest.
The first real spark comes on Tuesday, September 8th in the afternoon. Swell drops to 4 ft from the SSW, but the wind goes glassy – dead calm. The swell period is long, around 17 seconds. Combined energy climbs to 1395 (strong). That’s a proper groundswell on the reef, and it’ll be your first standout session if you can get out.
Friday morning, September 11th is another good one: a clean 5 ft SSW swell with a 16-second period and light offshore wind from the ESE. Combined energy is 1337 (strong). For an advanced surfer on the reef, that’s the kind of day you circle on the calendar.
The weekend of Sept 13th sees the swell building – up to 6 ft from the SW, periods hitting 17-18 seconds. Saturday afternoon (Sept 12th) shows moderate energy (1732) with light winds. But the best days look to be Monday, September 14th morning, and especially Tuesday, September 15th afternoon. Tuesday afternoon (Sept 15th) has 6 ft of SSW swell, a 15-second period, combined energy of 1173 (strong), and glassy conditions. That’s a big, clean groundswell on a reef. The expert surfers will be frothing.
As we head into the third week (Sept 17th), the energy drops. Thursday morning has a clean 4 ft SSW, 14-second period, but the combined energy is down to 622 (moderate). Still surfable. Friday the 18th gets smaller and messy, with poor onshore wind picking up.
The one-two punch of standouts here: Tuesday afternoon, Sept 8th (glassy, long period) and Tuesday afternoon, Sept 15th (glassy, bigger, same quality). That’s top-tier surf for those who know the reef.
Crowds are often an issue here. Good luck.
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.
