The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks. We’ve only got one spot in the mix, and it’s a solid one.

We’re looking at Keramas. It’s a reef break, very consistent, and exposed to that SSW swell. That’s exactly what the guidance says it likes. The water temp is sitting at a pretty comfortable 80°, which is about average for this time of year, so no surprises there.

Now, straight up, the forecast is a bit of a slow burner for the first few days. We’ve got a moderate cross-onshore wind and a bit of chop spoiling the party initially. The energy in the water is decent – moderate wave energy (1155 – 1195) – but the cross-off conditions are just not letting it shine. You’re looking at 5ft of SSW swell with a long 15 to 16 second period, so the potential is there, but the surface is messy. The scores reflect that; it’s a marginal call. Wednesday and Thursday stay clean-ish with a light onshore wind, but the size drops a touch. The period is still long though, hitting 14 to 20 seconds, which for a beach/reef setup like Keramas can mean the waves pitch up nicely, but that longer period can also make the sets a bit inconsistent.

The real standout. Get your eyes on Friday the 28th of August. That morning we’ve got a 8ft SSW swell rolling in with a 16-second period. The energy jumps right up to strong, very strong territory (3139). The wind? Light and onshore. That’s about as good as it gets for a right-hander like this. It will be big and powerful – good shout for experienced surfers only. Beginners should sit this one out, as it’ll be well over their heads. The crowd factor? Keramas can get busy, so expect company.

Saturday the 29th is still fun, dropping to a 6ft SSW swell, still with clean offshore lines. The energy is still strong (1524). Sunday and Monday drop off in size again into the 4 to 5ft range, but the period stays long, so there will be some clean little runners.

Moving into the second week, there’s a pulse of energy again around Sunday the 6th and Monday the 7th of September. We’re seeing a 6ft to 7ft SSW swell with that long period and light onshore wind. The energy is back up into the strong range (2161 for the Monday morning). That’s a promising, but less certain, long-range call. The rest of the second week holds onto 5ft to 6ft SSW groundswell, but the winds tend to go a bit more cross-on again.

Overall, there aren’t huge gaps with no surf here; the waves are pretty consistent through the period. But if you’re looking for the one session to make a plan around, lock in that Friday morning, the 28th of August. It’s the biggest, punchiest, and cleanest option on the cards.

Stay wet,
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.
