The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for your neck of the woods. Let’s be honest from the get-go: it’s a pretty grim run ahead. The whole 16-day window looks like a write-off for decent surf. We’ve got a solid stretch of poor conditions with no real standout sessions to get excited about.
Starting Sunday afternoon, August 2nd, Kalama has a 7ft swell from the ENE, but it’s blowing onshore at 22 mph with a period of 8 seconds. The water temp is sitting at 80°, which is about average for this time of year. The combined energy is moderate at 847, but it’s all for nothing with that wind. That’s just the start of a long, bleak run.
From Monday, August 3rd, through to Sunday, August 9th, it’s more of the same – small to moderate swells between 3ft and 6ft, all from the ENE or E, with constant onshore or cross-onshore winds. The period is short, mostly 5 to 8 seconds, and the combined energy stays weak to moderate (78 to 411). Every single entry is flagged as “poor surf conditions.” There’s no relief in sight. The wind is relentless, chopping up any potential wave.
The second week doesn’t offer any hope either. From Monday, August 10th, through to Monday, August 17th, Kalama sees swell sizes pick up a bit, ranging from 5ft to 8ft, but the ENE wind doesn’t let up, blowing 12 to 25 mph, mostly cross-onshore. The period stays short at 7–8 seconds, with combined energy climbing from 187 to 681 (moderate to strong). But again, every single entry is “poor surf conditions.” For a beach setup like this, with that much wind, you’d be better off rigging a kite than paddling a surfboard.
There are no good options at all. The forecast is a total blank for quality surf. This is one of those stretches where the weather just won’t cooperate. Things can change, but right now, I’d say save your energy and wait for a better forecast.
Rusty.

Information about the Kalama Surf forecast
The above surf forecast table for Kalama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kalama can be found by selecting the local surf guide option on the grey menu. Our Kalama 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 (Kalama) 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 Kalama 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.
Kalama is 1 km (1 miles) from Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
