Alright, Rusty here with the imperial version of that same ugly story.
We’ve got a solid 16-day window, but it’s mostly a write-off for proper surfing. The swell is there, no doubt—running between 3 ft and 7 ft with some strong combined energy in the 1500 to 2800 range—so the ocean’s got plenty of grunt. But the wind is the villain. It’s locked in from the SE to ESE at 15 to 22 mph, a fresh cross-onshore breeze that’s tearing the surface up into lumpy, choppy junk. Every single day is marked as “poor surf conditions.”
The only break in the game is Ampang, a reef that’s already inconsistent. It’s fairly open to the swell, coming mostly from the SSW and SW, but the ideal direction would be SSE, so it’s not perfectly aligned. Water temp is about 82°, pretty normal for this time of year. The swell period is often in the 15-18 second range—that’s long-period groundswell—which brings good energy but also big gaps between sets. With that cross-onshore wind, the waves will be jumbled and hard to ride. Most days have swell over 5 ft, and some push over 8 ft, so beginners should stay out, and even experts will find it messy.
There’s a brief quiet period around July 12th, where the swell drops to about 3 ft and the wind eases to 9-15 mph, still cross-on though, with energy down to 445-500. Slightly calmer, but still not good. Into the second week, from the 18th onward, the swell builds back to 5 ft to 7 ft with strong energy, but the wind stays SE cross-on and fresh, 15-22 mph.
Bottom line: with that constant lumpy wind and choppy water, this setup is more suited to kite surfing than a surfboard. There isn’t a single standout session in the whole outlook—near-term or long-range. It’s a rare blank stretch, and while things can turn, I wouldn’t hold my breath for the next two weeks.
Rusty.

Information about the Ampang Surf forecast
The above surf forecast table for Ampang provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ampang can be found by selecting the local surf guide option on the grey menu. Our Ampang 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 (Ampang) 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 Ampang 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.
Ampang is 27 km (17 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.
