The Lowdown
Alright, Rusty here again. Here's the same scoop in feet and miles per hour for those who think metric is a foreign language.
Keramas is looking at a mix of SSW swell over the next two weeks, but the wind's gonna be a constant headache. Water temp is about 82°F, which is a touch warmer than usual for this time of year—nice.
Starting Friday 17th through Sunday 19th, waves are 3.5 to 4.5 ft, with a long period of 13 to 16 seconds from the SSW. That's proper groundswell. But a steady 9 to 12 mph SE cross-onshore wind messes up the surface. Not worth suiting up unless you're really keen on a chop session.
Monday 20th jumps to 6 to 6.5 ft, combined energy hitting 2237 (strong). Same cross-onshore SE wind at 9 mph. You might get a few clean ones on the better tides, but it's still marginal.
Mid-week—Tuesday 21st to Friday 24th—drops back to 3 to 5.5 ft, winds stay SE, and it's either choppy or onshore. A few moments with "on" wind state (SE direction but unsure if truly offshore) pop up, but overall poor.
Now for the highlights. Tuesday 28th July and Wednesday 29th July are your best chances. Tuesday morning: 4.5 ft SSW swell, 18-second period, energy 1469, and light SE wind at 6 mph with an "on" state—could glass up. Wednesday morning: 6 ft at 16 seconds, energy 1851, again light SE 6 mph. That's chest-to-head-high waves with serious punch, and if the wind behaves, Keramas will offer long, peeling lefts. The reef, the consistent swell direction, and the light winds make these the standout days. Crowds can show up sometimes, but midweek mornings are your friend.
After that, the swell holds between 3.5 and 6 ft through the end of July, but winds remain SE. Thursday 30th and Friday 31st have light winds (6 mph, "on" state) giving you a shot, but the quality is still only marginal. Saturday 1st

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.
