Medewi Surf Forecast and Surf Report

Alright, Rusty here again, but this time in feet and miles per hour for you.

Let’s be real: the next little while is a bit of a mixed bag. There’s no shortage of swell – a solid SSW groundswell is rolling in, with a lot of energy behind it (we’re talking moderate to strong combined energy values ranging from 381 to 1869). The problem is the wind. It’s blowing cross-onshore from the SSE/SE at 9-12 mph pretty much all day, every day, making for choppy, bumpy conditions. Not the clean, glassy surf we’re after.

For the first week, from Thursday the 3rd right through to Monday the 7th of September, it’s mostly “poor” or “marginal.” The swell is there, with heights around 3-5 ft and a period mostly between 14 and 16 seconds – a nice long period groundswell that will wrap into Medewi (Bali) nicely. But that wind just chops it up. It’s going to be rough. If you’re into kite surfing, this setup might actually be more fun than paddling.

Things get a bit more promising after that. From Tuesday the 8th of September through mid-month, the swell builds. We’re seeing consistent 5-6 ft waves, sometimes hitting 6 ft, with the period staying in that 12-16 second range. The combined energy jumps up into the four-digit range (over 1000), meaning there’s some real power out there. The wind eases at times to a light breeze (6-9 mph), but it’s still cross-onshore. It’s still “marginal” – not perfect, but rideable. The standout moments will be the mornings of Wednesday the 9th and Friday the 11th of September, when the wind drops to a light breeze (6 mph) and the swell is a solid 5-6 ft from the SSW. It’ll still have a bit of texture, but it’ll be the cleanest you’ll see in this forecast.

For beginners, watch out when the swell is over 5 ft, especially on the 7th and 8th – that’s getting into intermediate territory. With a period over 15 seconds, Medewi is a classic point and river mouth break, so it’ll handle that long period energy well and won't just close out.

After the 12th of September, the swell fades. Heights drop back to 3-5 ft, and the combined energy drops too (down to around 500-800). The wind stays cross-onshore. It’s a slow finish, with only marginal or poor conditions forecast for the last few days.

Overall, there’s no perfect session. The best bet is to hit the lighter wind windows, like the mornings of September 9th and 11th, for a chance at cleaner waves. Crowds at Medewi can be a problem sometimes, so keep your eyes peeled on the better days.

The water temp is a warm 80°F, which is normal for this time of year – no surprises there.

So, to wrap it up: keep your hopes in check. There’s plenty of swell, but that persistent cross-onshore wind is the deal-breaker. If you’re keen, go for the lighter wind days.

Rusty.
