The Lowdown

Alright, this is Rusty comin' at ya from the lineup. Let's talk about what we've got cookin' over the next couple of weeks.

First up, the water temp is sittin' at a steady 81°, which is pretty much bang on average for this time of year, so no surprises there. The main story, though, is that we're lookin' at a long, drawn-out period of so-so conditions before a serious pulse of energy shows up way down the line.

Right now, we're stuck in a bit of a funk. From Friday the 28th of August all the way through to Monday the 7th of September, it's a real mixed bag of cross-onshore winds and choppy surfaces. The swell is there but it's not cooperating with the wind. The first few days have a decent amount of energy, that Friday morning alone has the combined energy at a strong 1749, but that cross-on wind just messes the face up. It's going to feel like a lot of work for not much reward. Things go pretty quiet for a bit after that.

Now, the real standout, the one worth circling on the calendar, is that build starting Friday the 11th of September. For the morning, you're lookin' at 5ft of SSW groundswell with a long 16-second period. The combined energy is a massive 2203, talkin' about a serious push of water. The wind is a light cross-onshore from the S, just 6 mph, which will keep things fairly clean. But the session to aim for is the afternoon of that same Friday the 11th. We're talkin' 8ft of SSW groundswell with an 18-second period, and the combined energy is absolutely pumping at 4060. That is some serious juice.

At Medewi, a long period groundswell like this, bang on from the SSW, is exactly what the doctor ordered for that point break setup. With a period that long, the sets will have some serious power and the wave will line up beautifully along the rock shelf. That kind of power is for experienced surfers only, it'll be way too much for the beginners.

Even into Saturday the 12th, it's still solid with 8ft in the morning and the wind staying light. The downside is that Medewi can draw a crowd, and with this kind of forecast, the place will be packed. Expect company.

So, to wrap it up, the next week or so is a bit of a write-off for quality. Keep your gear ready for that big pulse on Friday the 11th of September. That's your window for the best waves of the period, no question.

Stay stoked,
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.

Medewi is 27 km (17 miles) from Negara. If you plan a holiday in West Coast of Bali, look for hotels and other accommodation in Negara. Negara has rooms for a wide range of budgets as well as car hire and transport links.
