The Lowdown
G’day, Rusty here. Let’s have a look at the next couple of weeks at Keramas. It’s a reef break that’s very consistent, and the swell’s got a sweet SSW direction lining up with what it loves. But fair warning – the first week is a mess. Cross-onshore winds every day, mostly from the SE, chopping things up. The water’s sitting at about 81°F which is pretty much average for this time of year – no weird anomaly to report.
Starting from Saturday 25 July morning, we’ve got a 4ft SSW swell with a long 15-second period, so there’s groundswell energy in the water (combined energy 990 – moderate). But the wind is cross-on from the SE at 9 mph, and it’s just poor quality, choppy and bumpy. That carries through the afternoon. Sunday 26 July jumps to 7ft, but it’s short-period SE windswell at 9 seconds and the wind is up to 12 mph cross-on – not worth paddling out. Monday 27 is more of the same: 7ft with 8-second period, choppy as hell. Tuesday 28 drops to 3ft but has a beautiful 16-second SSW groundswell – still trashed by cross-onshore wind though. Wednesday 29 and Thursday 30 are in the 4–5ft range, SSW direction, moderate energy (880–1331), but still cross-onshore. Friday 31 July morning shows a 3ft 18-second SSW groundswell, energy at 1197, and the wind drops to 9 mph – still cross-on, but the lighter breeze means it’s only fairly choppy. That’s the first real hint of improvement. The afternoon gets even lighter at 6 mph, still cross-on, but with small wind ripples.
Now, Saturday 1 August and Sunday 2 August are where it starts getting interesting. Saturday morning has a 4ft SSW 16-second swell, energy at 1511 (moderate-strong), and the wind is light at 6 mph cross-on. By afternoon, the swell builds to 6ft, same long period, energy jumps to 1888. Sunday 2 August morning pushes 5ft with 16-second period, and the combined energy is a solid 3373 – that’s strong wave energy. The wind is still light cross-on, so it’s rideable but not glassy. These two days are the best of the early run, but they’re not standouts because the cross-on wind stops it from being pristine.
The real standout comes later. Monday 3 August has 6ft SSW 16-second groundswell, energy at 1701, wind still cross-on 9 mph. But then look at Tuesday 4 August morning – for the first time, the wind goes true offshore from the SE at 9 mph with a 5ft SSW 14-second swell (energy 1359). The afternoon stays cross-on though. Wednesday 5 August morning also has offshore wind, 6ft SSW 14-second swell (energy 1116). Thursday 6 August through to Friday 7 August all have offshore winds from the SSE, with swell heights 5–6ft and periods up to 18 seconds. Friday 7 August afternoon sees a 5ft SSW 18-second groundswell with strong energy at 2345.
But the absolute highlight is Saturday 8 August. Morning: 8ft SSW 17-second groundswell, combined energy a massive 3896 (strong), with light cross-on wind. The afternoon session gets even better – same 8ft swell, 17-second period, energy at 4206, and the wind turns offshore from the SE at 9 mph. That’s expert territory size-wise (over 8ft), so it’s for the skilled crew only. That’s a proper big, clean, groundswell day at Keramas with offshore wind – the best on offer in the whole 16-day window. Sunday 9 August hangs on with 8–7ft SSW 16-second swell, still decent but the wind is cross-on again in the morning, then offshore in the afternoon.
Crowds are possible at Keramas, so get in early for that Saturday 8 August session. This reef will be handling that long-period SSW groundswell beautifully.
Rusty.

Information about the Keramas Surf forecast
The above surf forecast table for Keramas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Keramas can be found by selecting the local surf guide option on the grey menu. Our Keramas 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 (Keramas) 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 Keramas 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.
Keramas is 10 km (6 miles) from Klungkung. If you plan a holiday in Sanur - Bali, look for hotels and other accommodation in Klungkung. Klungkung has rooms for a wide range of budgets as well as car hire and transport links.
