The Lowdown
G’day, Rusty here. Let’s cut through it. We’ve got a solid 16-day window ahead, but it’s not all firing at once. The early part of the week is messy, but there’s a proper pulse of long-period groundswell building towards mid-week, and then another strong push early in the second week that looks like the real standout. There are a few flat-ish, choppy days in there, so pick your moments.
First up, the opening days are a write-off. Sunday the 9th is blown out with a strong cross-shore and messy cross-chop, not worth getting wet. Monday the 10th cleans up a bit but the swell is marginal – you’re looking at around 8ft to 8ft from the SSW with a fresh breeze, so it’s gutless and a bit lumpy under the surface.
The first real glimpse of something decent comes Tuesday the 11th. The wind eases off to a gentle breeze, cross-off from the east, and the swell is still around 6ft from the SSW with a 12-second period. It’s clean out there – you’ll get some lined-up walls, but nothing too serious. The energy is moderate (1120). Wednesday the 12th is where it starts to get interesting. The swell holds around 6ft to 6ft, but it’s a proper long-period WSW groundswell – 18 seconds. That’s a long fetch, plenty of push. Wind is offshore, light and clean from the ENE/NE all day. This is a good day for experienced surfers – the wave energy picks up to strong (2045 and 2106). The sets will be well-spaced, which makes the paddle out easier, but the juice is there. For a beach break, that long period can make things a bit straight, but it’ll still be fun.
Thursday the 13th sees the swell bump up to 8ft from the WSW with a 17-second period. The morning is cross-off with a moderate breeze, still clean. The afternoon goes fully offshore with a moderate breeze and that’s when it should be cranking – wave energy is strong (3378 morning, 2731 afternoon). This is a bigger, more powerful day, so you need to know what you’re doing. It’s pushing near the 8ft mark, so definitely not for beginners.
Friday the 14th and Saturday the 15th are a step back down. The swell drops to 5ft to 6ft, period backs off to 14 seconds or so. Friday’s afternoon looks alright – light breeze and clean, with a cross-off wind. Saturday gets a bit messier with a light cross-shore, and the afternoon goes onshore. There’s still surf, but it’s not special.
Now, Sunday the 16th – the morning is glassy. Wind is virtually nothing, just a slight air from the NW. The swell is 6ft at 13 seconds, and it’s clean as a whistle. That’s a fun, user-friendly day. Not big, but the conditions will make it feel better than the size suggests.
Then we get to the highlight. Monday the 17th. This is the one to circle. The swell jumps to 10ft from the WSW with a 16-second period, and the morning is glassy. The combined energy is very strong – 4935. This is a serious groundswell, and with no wind, the lineup is going to be clean and heavy. This is strictly for experienced surfers – 10ft is well over that 8ft mark. It’s powerful, it’s raw, and it’s going to be one of those sessions you remember. The afternoon gets a light cross-onshore, so get on it early.
The rest of the second week is a bit of a mixed bag. Tuesday the 18th drops to 7ft, but it’s a bit cross-shore and lumpy. Wednesday the 19th has a similar size, 8ft, but the wind is light cross-onshore, so it’s not as clean. Thursday the 20th is smaller and messy. Friday the 21st has a clean morning – offshore light breeze, 6ft from the SW at 11 seconds – that’s a fun little window. Then the weekend of the 22nd and 23rd gets blown out again with a moderate to fresh cross-shore and a cross-chop – not good. Monday the 24th finishes the run on a high note: 8ft from the WSW with a 14-second period, gentle cross-off wind, and clean conditions. Wave energy is strong (2344). That’s another solid session for the more experienced crew.
As for the water, it’s running about average for this time of year, so not much to worry about there.
Overall, the standout is Monday the 17th – big, clean, powerful. The other day worth getting excited about is Wednesday the 12th, for the long-period quality with offshore winds. Everything else is pick-your-moment stuff.
Later, Rusty.

Information about the Eerste Steen Surf forecast
The above surf forecast table for Eerste Steen provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Eerste Steen can be found by selecting the local surf guide option on the grey menu. Our Eerste Steen 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 (Eerste Steen) 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 Eerste Steen 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.
