The Lowdown
Alright folks, Rusty here. Let’s get into it. Over the next 16 days, Keramas is gonna see a steady supply of SSW swell – just what this reef wants to see. But here’s the rub: most of the time the wind is coming from the southeast or south-southeast, blowing onshore or cross-onshore. That’s going to put a chop on the surface and keep things from being truly clean. The water’s sitting at 80.4°F, which is dead average for this time of year – nothing weird there.
The first few days – Thursday 10th through Saturday 12th – the swell is hanging between 4.3ft and 6.6ft, with periods of 14–16 seconds. Energy numbers are in the 110

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.
