The Lowdown
Right, let’s have a look at the next couple of weeks for Windansea. It’s a bit of a slow burn, to be honest. The swell is hanging around, but it’s small and the winds are mostly going to mess with the surface. We’re looking at a few days of onshore slop before things clean up. The water is sitting at 74°, which is a good 6° warmer than usual for this time of year – that’s properly unusual, a real treat for a late swim between sets.
The first few days are pretty grim. Saturday the 12th is small, that 2ft SW swell is all chopped up by a 6 mph west breeze. Sunday the 13th is much the same story, with a cross-on wind putting a texture on it. Monday the 14th has a bit more push, 4ft, but it’s a short-period 8-second windswell and the cross-onshore is making it lumpy. The wave energy is moderate though, but it’s not going to be any good to ride. Tuesday the 15th drops right back off.
Now, we start to see the swell period bump up, but it's still pretty junky. Wednesday the 16th has a bit of a longer period at 17 seconds, but the swell is only 3ft. It’s onshore and the conditions are still poor. Thursday and Friday are more of the same – waist-high slop with cross-onshore winds. To be fair, Friday the 18th morning has a bit more energy, but the comment is still marginal at best.
The following week, from the 19th onwards, the period stays long, pushing 16-18 seconds, but the size is stubbornly stuck around the 2ft to 3ft mark. The winds are lighter and a bit more offshore at times, which is something. The standout from this second week looks like Monday the 21st. On the 21st, we're looking at 3ft of SW swell with a long 17-second period. The energy is strong, and the breeze is light. It’s still on the small side, and the tide will be making it a bit tricky, but it could be the cleanest, most organised surf of the whole period. The long period means it might be a bit straight at a beach break, but for a reef like Windansea, it should offer some proper shape. It’s still not big, so it’s not going to be a classic, but it’s the best on offer.
The rest of that week is pretty samey – small, longer-period SW swell, with light winds. Tuesday the 22nd has a similar 3ft, and then it fades back to 3ft for the rest of the run. The energy stays moderate to strong through the 21st and 22nd, then weakens a bit. Week two is just a promise of cleaner, organised lines, but nothing with any real size. Crowds are likely at this spot, it’s often busy, but with surf this small, only the keenest will be out.
So, overall, it's a quiet outlook. There's no real swell on the horizon, but the improved winds and long-period energy around the 21st and 22nd are the pick of a pretty average bunch. Keep an eye on that.

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