Waimanalo Surf Forecast and Surf Report

Hey, Rusty again. Let's cut through it. The surf outlook for Waimanalo over the next couple of weeks is pretty grim. The wind is the problem, blowing hard and onshore for most of the run, just wrecking the waves. Water temp is around 81°F, pretty normal for this time of year, so no worries there.

We start Monday, September 14th, and you can stay on the beach. There's a weak NE windswell of 3ft to 4ft from the NE, with a short period of 8 seconds and low energy (112-153). The wind is onshore from the ENE at 12 mph, making it a mess. That's the story for the whole first week. The swell picks up, but so does the wind. By Wednesday the 16th, we've got 4ft to 5ft from the ENE, but it's still a junky period (6 seconds) and the onshore wind is a fresh 19 mph. Energy climbs into the moderate range (206), but the quality is zero. Thursday the 17th sees the swell hit 7ft from the ENE with moderate energy (416-603), but it's all slop under a fresh breeze. Even when the swell jumps to 7ft from the E on Wednesday the 23rd, with a much longer period of 11 seconds and very strong energy (1052), the wind is still howling onshore at 19 mph. That's just raw, blown-out power for experts only.

There's one small window. The morning of Sunday, September 27th shows a new pulse of 4ft swell from the north with a solid 10-second period and moderate energy (441). The wind is only a light breeze at 6 mph from the north, giving us a cross-onshore flow. It's still not glassy, but it's the most surfable it's going to get in this entire forecast. It's a marginal call, but that's your best bet. The rest of that week stays small and mostly poor.

So, your best option? That Sunday the 27th morning session is the only one that looks even close to worthwhile. The rest of this 16-day run is largely a write-off. A huge chunk of the first two weeks is just blown-out slop. With the wind so strong and the surf messy, the beach might be more interesting for kite surfing than paddle surfing.

Rusty.
