The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up for the next couple of weeks. It’s a mixed bag, but there’s a light at the end of the tunnel.
The overall pattern is pretty average for the first week, with a persistent cross-onshore breeze and a lot of "marginal" calls. The water is sitting at 80°, which is pretty much bang on average for this time of year, so no wetsuit worries. The real standout window is shaping up for the second weekend, and it’s worth keeping an eye on.
We kick things off Sunday morning, September 6th, with a 3ft SSW swell at Medewi. The period is a very long 17 seconds, which is proper groundswell. That’s excellent for this point-and-beach setup, but the wind is a SSE cross-on at 9 mph, so it’s going to be a bit lumpy and choppy. The combined energy is moderate (1181), but it’s not going to be a clean session. Pretty much the same story carries through the whole first week, with swell sizes bobbing between 3ft and 6ft, and that persistent cross-onshore wind keeping things from getting truly glassy. The energy kicks up a notch on Tuesday the 8th afternoon (2120), and again on Wednesday the 9th (1826), but the wind is still a problem. The real dampener is that the wind is almost always cross-onshore, so the waves are going to be fairly choppy. It’s a frustrating stretch.
After a drop in quality around the 12th and 13th, the second week looks a bit more promising. The wind lightens up a touch, and the swell starts to build. The real standout is the weekend of September 19th and 20th. Saturday the 19th morning sees a 7ft SSW swell with a 16-second period, and the combined energy jumps to a strong 2002. This is proper size. A 7ft swell at Medewi is getting into the meaty, fun zone, and the SSW direction is right on the money for the break. The wind is still a cross-on (SSE), but at 9 mph it’s manageable. This is the best-looking stretch on the board. The swell holds into Sunday the 20th morning at 7ft (2191 energy), but it’s still a touch breezy. If you’re an intermediate or better, this is your window.
After that, we get a bit of relief on the morning of Monday the 21st, when the wind finally swings onshore (S) at a light 6 mph. That’s the cleanest wind we’ve seen all forecast. The swell is 5ft from the SSW with a 14-second period, which is a solid combo. It’s a shame the energy is on the lower side (989), but the conditions will be much cleaner than what we’ve been dealing with.
So, the pick of the litter is the weekend of the 19th and 20th. That’s where the swell is biggest, the energy is highest, and the waves have the best chance of being fun despite the breeze. Keep an eye on that Monday the 21st morning too, as it might be the cleanest, if smaller, day.
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.
