The Lowdown
Alright, Rusty here. Let’s talk about the surf coming up at Medewi.
The next few days are looking pretty average for this classic left-hander. We’ve got a long-period SSW groundswell rolling in, but the wind is the story here – it’s persistently cross-on or cross-shore, keeping things messy. The first real pulse of energy shows up Saturday the 22nd, with a 5ft swell from the SSW at a solid 16 seconds. The combined energy is strong (1387), but that SE cross-breeze at 12 mph is putting a chop on it. It’s surfable, but not the clean, glassy Medewi we all dream of.
Sunday the 23rd is much the same – 5ft SSW swell, but the wind swings cross-onshore and the quality drops. Not the day to clear your calendar. Monday the 24th and Tuesday the 25th stay in that same pattern, with the swell easing and the wind staying on it. The water temperature is about average for this time of year.
The best window in this whole 16-day stretch looks like Friday the 28th. The swell jumps up to 6ft from the SSW, still with a nice long 16-second period, and the combined energy hits a punchy 1841. The wind is still cross-onshore from the SSE, but at a lighter 9 mph in the morning, it’s going to be the cleanest we see. This is the standout, but it’s still not perfect – that cross-shore element means you’ll be fighting a bit of texture on the face. If you’re an intermediate or better, it’s worth a look.
After that, things drop off again. The swell backs off through the end of August and into the first week of September, with most days rated poor. There’s a glimmer on Tuesday the 1st of September, with a 4ft SW groundswell and a 18-second period – that’s some proper energy (1527) – but the wind is still cross-shore from the SE. The long period might make it a little walled-off at the main peak, but the point could handle it. It’s a long-range call, so keep an eye on it, but don’t book the time off just yet.
Overall, Medewi has a consistent supply of swell, but the wind is going to keep it from firing. Friday the 28th is your best bet for a decent session. The rest of the run is mostly a write-off unless the forecast changes. For the level of energy coming in, the quality is disappointing. It’s a wait-and-see kind of outlook.
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.
