The Lowdown
G’day, Rusty here.
Alright, let’s be straight—this 16-day outlook for Medewi isn’t firing on all cylinders. We’ve got a steady, long-period groundswell from the SSW hanging around most of the time, but the wind is the problem. For the first week and a half, it’s mostly a cross-onshore breeze that’s keeping the surface messy. The combined swell energy starts moderate around 1025 on the 13th and bounces around, but the quality is lacking. There’s no real standout early on, but the back half of the window shows some life.
Your best bet is looking at Friday the 25th. The swell is pumping at 7ft from the SSW, with a long period of 18 seconds. That’s proper groundswell with a strong combined energy of 2670. The wind eases to a gentle breeze, and by the afternoon it turns cross-shore, cleaning it up a touch. That long period works a treat at Medewi’s point and reef, giving you better-shaped waves with longer lulls. But at that size—over 8ft—it’s strictly for the experienced crowd. Beginners, stay on the sand.
The water temp is about average for this time of year.
Saturday the 26th morning is also worth a look. The wind goes offshore from the S, light at 10 km/h. Swell drops to 6ft from the SSW, period 16 seconds, combined energy 1341. That offshore wind will give you clean, glassy walls. It’s still listed as marginal due to tide, but if the timing’s right, that’s the cleanest wave of the whole stretch.
The 27th (Sunday) morning has a light cross-on breeze with 6ft swell, decent but not as clean. The 23rd and 24th also have solid 6ft swell, but the wind keeps it choppy—better for kite surfing than paddling.
The first nine days are a grind. There’s a gap from the 13th to the 20th where conditions are mostly poor to marginal. Don’t expect much. After that, the energy builds, and that final week holds the real promise.
So, I’d pencil in Friday 25th arvo or the offshore window on Saturday 26th morning. That’s where it’s at. The rest? You’ll be working hard for not much.
Rusty.

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