The Lowdown

Alright, let’s break it down for Keramas over the next couple of weeks. This is a reef break that’s very consistent, and it’s dialed in for south-southwest swell, which is exactly what we’re gettin’. Water temp is about average for this time of year, nothin’ weird.

The story here is a long stretch of cross-onshore and onshore wind, which is gonna keep the surface a bit bumpy and messy. The swell is there, but it’s not gonna be glassy. The real standout is the end of the first week, around Friday the 28th of August. That morning we’re lookin’ at a solid 8ft of SSW groundswell with a very long 16 second period, and the combined energy is a strong 3065 – that’s serious power. The wind is cross-onshore, so it’s not perfect, but for a reef break like this, that size and period will pump out some heavy, well-shaped waves. It’s over 8ft though, so this is only for the experts. That Friday afternoon is still solid at 8ft, but the wind goes onshore, so the morning is the best window.

After that, the swell drops off into the weekend, with cleaner conditions on Sunday the 30th – lighter winds, onshore, but the swell is only 4ft in the morning, then jumps to 7ft in the afternoon, but that’s a shorter period SSE swell. The second week is more hit-and-miss, with a slight bump in energy around Tuesday the 1st of September, with 6ft SSW swell and a very long 19 second period, and combined energy of 2581. Still cross-onshore though. The rest of the week fades into smaller, onshore slop.

Bottom line: if you’re an expert, the Friday 28th morning is the one to circle. It’s got the size, the direction, and the grunt. Just expect some chop. The rest of the run is pretty average for Keramas – not flat, but nothin’ to write home about.

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.
