The Lowdown
G’day, Rusty here.
Right off the bat, this stretch of coast is going to keep you guessing over the next two weeks. We start flat and messy, get a couple of clean windows in the middle, then it turns too big and unruly for most of us. There’s one real gem in there—don’t sleep on it.
From Sunday the 13th through Tuesday the 15th, it’s a total washout. Onshore winds are blowing straight in, the swell is mixed up, and there’s no quality in the water. Energy readings are moderate at best (529, 470, 700, then 1823), but none of it is translating into ridable waves. It’s just chop and wind.
Wednesday the 16th offers a slight glimmer. By the afternoon, the wind turns offshore (SSW 15 km/h) and conditions clean up. Swell is 1.9m from E at 10 seconds, energy at 761. Still marginal, but you can feel something building. Water temp is 21.0°, about average for this time of year—nothing special.
Thursday the 17th morning is the first proper session. Offshore breeze (SSW 20 km/h), swell 1.5m from E at 10 seconds, energy at 910. It’s clean, lined up, and fun-sized. If you’re flexible with your schedule, this is a strong bet.
Friday the 18th and Saturday the 19th are frustrating. The swell pushes to 1.9m and then 2.5m, but the period is stuck at 8 seconds—that’s junky wind swell. Even with clean winds, it’s fat and crumbly. Saturday afternoon hits 2.5m with energy at 1619, but that’s too big for this break and the short period makes it a mess. Beginners, stay away—over 1.5m is already pushing it.
Then comes the standout: Sunday the 20th, morning. Glassy conditions, light SE wind at 5 km/h, swell 1.6m from SE at 10 seconds, energy at 667. This is your window. Clean, smooth, offshore, and not too crowded. If you only surf one session all fortnight, make it this one.
Monday the 21st keeps the quality—morning offshore (SSW 20 km/h), 1.4m from SE at 10 seconds, energy at 517. Slightly smaller but still clean. Tuesday the 22nd is a drop-off; the morning has offshore winds but the period crashes to 6 seconds, making it weak and choppy. Afternoon is cross-shore and messy.
From Tuesday afternoon through Wednesday the 23rd, it’s flat and poor. Swell drops below a metre, onshore winds return, and energy numbers are weak (271-290). Nothing doing.
Thursday the 24th is the big red flag. Swell jumps to 2.4m from S at 8 seconds, energy at 804, with offshore winds. But the note says it’s too big for this break. That’s not a suggestion—it’s a warning. Expert-only, and even then, it’s going to be closing out. Same for the afternoon at 2.0m.
Friday the 25th is a write-off—onshore, poor, energy fading. Saturday the 26th is flat and messy again (353-430). Sunday the 27th afternoon shows a small, long-period pulse—0.7m from SSW at 14 seconds, clean and glassy with a light offshore (SW 10 km/h). Tiny, but pretty.
Monday the 28th is the final hammer. Swell hits 2.5m, energy at 2017-2067, from ESE at 9 seconds. Morning is offshore but it’s too big for this spot. Afternoon brings heavy rain and a stronger cross-offshore wind, but still 2.5m. This is kite-surfing territory, not paddle-surfing.
So here’s the deal: Sunday the 20th morning is the best on offer—clean, chest-high, offshore. Thursday the 17th morning is the runner-up—slightly bigger, still manageable. After that, it’s either too flat, too onshore, or too big. If you’re a beginner, give the 2.5m days a wide berth. Experts,

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