The Lowdown
Alright folks, Rusty here. Let's look at what's on offer for the next couple of weeks.
We've got a solid, consistent run of SSW groundswell hitting Keramas, but the wind is the main story here. For the most part, we're dealing with a cross-onshore breeze that's keeping things from being truly epic. The water is feeling pretty normal for this time of year at 81°.
The standout window is looking like Thursday, August 13th. We've got a big 10ft SSW swell rolling in with a long 17 second period, packing some serious punch (combined energy of 5853). The wind is on it in the morning, which is a huge plus, meaning it'll be glassy and clean. That's the pick of the period for experienced surfers, as it's well over the 8ft mark and only for the crew who know what they're doing. The afternoon stays cross-onshore, but still a solid 10ft. The following days, August 14th and 15th, drop back to a more manageable 8ft and 4ft, but the wind is still a bit messy.
Then, looking ahead to Wednesday, August 19th, we've got another really promising day. Again, 8ft SSW swell with a long 18 second period, combined energy up at 4042. The wind is light and onshore from the SSE in the morning, swinging southerly in the afternoon. That light breeze will make for some clean, powerful waves. It's a week and a half out, so keep an eye on the charts, but it's got real potential.
Overall, the swell is there, but the wind is the gatekeeper. Get on it the 13th or the 19th for the best chance of a clean session.
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.
