The Lowdown
Alright, listen up. Gotta be honest with you, the next couple weeks at Medewi are looking pretty average. There's swell, sure, but the wind's gonna be chopping it up most of the time. It's not a total loss, but you gotta pick your moments.
Water temp's about 79°, pretty normal for this time of year, so no need for a thick suit.
Let's run through it. You got a start on Sunday the 16th. Solid SSW groundswell at 6ft with a long 16-second period. The energy is strong, combined reading of 1411. But the wind is cross-onshore from the SSE at 6 mph, putting a bit of texture on the waves. It's surfable, but not glassy. Afternoon drops to 5ft, still long period, but wind picks up a bit and goes more cross, making it a little lumpy.
Monday the 17th, the swell backs down to 4ft and the period drops to 14 seconds. Energy is weak at 536. This is pretty small and the cross-onshore wind will mess it up. Not worth getting wet for.
Tuesday the 18th, the swell builds again. Morning is small at 3ft, but the afternoon jumps to 5ft with a 16-second period, and the energy is pumping at 2187. But again, cross-onshore wind, so it's a bit of a fight.
Wednesday the 19th is your best bet. Morning has 6ft of SSW swell with an 18-second period and energy at 1729. Wind is lighter, only 6 mph, but still cross-onshore. The afternoon gets a touch bigger at 6ft and the wind backs off to a light cross, making it cleaner. This is the standout. The direction is SSW, right in the sweet spot for Medewi's points.
Thursday the 20th is similar size, 6ft in the morning, but wind is stronger and more onshore, making it chunkier. Afternoon drops to 6ft with a slight shift to SW.
Then the wind really starts blowing. Friday the 21st through Sunday the 23rd, moderate cross-onshore winds at 12 mph. Swell is still there, 6ft to 6ft, but it'll be choppy and blown-out. This looks more like kite-surfing conditions than clean surf.
After that, it fades. Swell drops to the 4ft to 5ft range for the rest of the week, and winds stay cross-onshore. There's a pulse of longer-period SW swell around the 27th, but it's small, only 3ft, and the wind is still up.
Looking further out, the weekend of the 29th and 30th is poor. Swell drops under 3ft and wind stays onshore. There's a tiny bump on the 30th with a 19-second period, but it's only 4ft. A tease.
So, the call is this: get out on Wednesday the 19th. That's the day. The afternoon looks best with lighter cross-shore wind, and that 6ft SSW swell on a long 17-second period will have some push. Medewi's a fairly consistent spot, but it'll be breaking. Just watch for the cross-onshore bump. Crowds are sometimes an issue here, but on a Wednesday afternoon you might score a bit more room.
Beyond that, it's a waiting game. Nothing else looks like it'll deliver clean conditions for the next 16 days. The pattern is set for a run of average surf.
Keep an eye on it, though. Forecasts change, and if the wind swings offshore, that south swell could turn into something.
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.
