The Lowdown

Alright, Rusty here again. Let’s break it down for Mawi in feet and mph.

The water’s sitting at 27°, which is right on the money for this time of year – feels normal. Starting Saturday the 15th, we’ve got a solid 8 ft swell out of the SSW with a very long 17 second period – 3031 units of energy (moderate to strong). Wind is cross-off from the ESE at 16 mph, clean but breezy. By Sunday morning the 16th, it’s pushing 7 ft with 16 second period, still cross-off and clean. This is a big, powerful reef break for advanced surfers only. Crowds are possible here.

The real standout window is Wednesday the 19th afternoon. Swell hits 8 ft from the SW, period at 18 seconds, and the wind eases to a gentle 9 mph cross-off. Energy jumps to 4249 (strong). That’s the best combination of size, power, and clean conditions – if you’re experienced, that’s your session.

Thursday the 20th morning goes to 10 ft from the SW at 16 seconds – expert only – with wind at 16 mph. Still cross-off, so clean, but serious size. The rest of the week holds solid 5 to 8 ft swells with energy in the 1000s and 2000s and moderate cross-off wind. No glass, but rideable.

Into the second week, Monday the 24th and Tuesday the 25th drop to 4 ft to 5 ft, energy under 1500 – weaker. Wind picks up by Wednesday the 26th to 19 mph, and energy falls to 861 (weak) – a real lull. Thursday the 27th afternoon shows a 7 ft SW swell at 18 seconds with 3140 energy, but wind is 16 mph. Friday the 28th morning offers 8 ft SSW at 3196 energy, still breezy.

The end of the outlook, Sunday the 30th, has a spike: 8 ft from the SW, 19 second period, 5000 energy (strong) at 16 mph wind. That’s 16 days out, so hope but don’t book your flight yet. For now, Wednesday the 19th afternoon is the clear winner.

Plenty of consistent SSW/SW groundswell the whole run, cross-off winds, and crowds possible at this reef. No real flat gaps – there’s always something.

Rusty.

Information about the Mawi Surf forecast

The above surf forecast table for Mawi provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mawi can be found by selecting the local surf guide option on the grey menu. Our Mawi 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 (Mawi) 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 Mawi 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.

Mawi is 25 km (16 miles) from the city of Praya. If you plan a holiday in South Coast of Lombok, look for hotels and other accommodation in Praya. Praya has rooms for a wide range of budgets as well as car hire and transport links.
