Keramas Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.

Right off the bat, we’ve got a solid run of swell aimed at the island, but the wind is going to be a real pain for the first few days. The water is sitting at 81°, which is pretty much spot on for this time of year, so that’s nice.

For the first four days, through to the 4th of September, the wind is coming from the SE, mostly cross-onshore at 12-18 mph. That’s going to mess up the surface pretty bad. Even though Keramas is picking up a consistent groundswell from the SSW, the wave energy is moderate to strong (2023 down to 689), the conditions are just too choppy and bumpy to get excited about. The swell is running 3 ft to 6 ft, period between 14 and 18 seconds, but it’s not worth paddling out for. The wind state is just a headache.

Now, hold on to your boards, because things start to change on the 5th of September. The wind backs off and swings more onshore from the SSE, but importantly, the wind speed drops to just 6 mph. The swell holds steady from the SSW, with the combined energy jumping up to 1433 and 1573. Still a bit of texture, but it’s starting to clean up.

The real standout window is the 7th through the 10th of September. This is the one to circle. The wind drops to a light breeze (6 mph) from the SSE, and it’s blowing straight offshore for Keramas. That’s the magic word. The swell is solid, between 6 ft and 8 ft from the SSW, with periods of 14 to 18 seconds, and the wave energy is strong – between 1768 and 3243. This is a proper, long-period groundswell hitting a reef break. The sets will be clean, lined up, and powerful. It’s getting into the expert zone at 8 ft, but for the crew that can handle it, this is the best on offer. Crowds are possible here, ’cause it’s a consistent spot.

After the 10th, the swell dips a bit, but the wind stays favorable. The 11th looks interesting, with a 6 ft SSW swell and a 17-second period, but the energy is still up there. Through the 12th and 13th, the size drops back to 4 ft to 6 ft, and the wind is light, so it’s still rideable, just not as punchy.

The second week, from the 14th to the 16th, the swell keeps ticking over. The 14th and 15th show a solid 5 ft to 6 ft SSW swell, with the wave energy staying moderate to strong (1043 to 1337). The wind is still light from the south, mostly offshore, so it’ll be clean. The 16th brings a nice 5 ft SSW swell with a 16-second period, and wind holding. It’s not the barnstormer of the first week, but it’s steady, clean, and fun.

If you’re a beginner, the swell is mostly over 5 ft, so it’s a bit of a step up. The big days on the 7th-10th are for the experienced crew only. For everyone else, the 14th through the 16th offers a more manageable size with clean conditions.

That’s the picture. The best days are the 7th to the 10th of September when the wind goes offshore and the swell is pumping. After that, it’s a steady, clean run of smaller waves.

Rusty.
