Trapdoors Surf Forecast and Surf Report

Alright folks, Rusty here with a look at Trapdoors over the next couple of weeks. Gotta be straight with you – this stretch is a mixed bag. We’ve got some solid swell windows, but you’ll need to pick your moments carefully because the wind and conditions can turn things ugly fast. The water temp is sitting at 68.2°F, which is pretty much bang on average for this time of year, nothing unusual there.

The main event kicks off this Tuesday afternoon (8 September) with a solid 6.6ft swell from the SSE, period around 9 seconds. The energy is moderate at 596, but the wind is a cross-off from the S at 12 mph, which should keep things reasonably clean, though the forecast says “marginal” thanks to some rain showers. This is a good session for advanced crew only – that 6.6ft at a point/river setup will be powerful and can get tricky. The swell direction from the SSE is not quite the optimum SE, but it’s close enough to work.

Things really wind up toward the end of the week. Thursday morning (10 September) sees a jump to 8.2ft from the SSE with a 9-second period. The energy is strong, clocking in at 1229, and with a cross-off wind from the S at 16 mph, it'll be a bumpy but clean ride. That’s big, heavy stuff – expert territory only. That same size and quality holds through Friday morning (11 September), with energy peaking at 1952, making for a serious, powerful ocean. The S wind keeps it cross-off, so shape could be decent, but you’ll be trading off with a strong breeze.

For the average punter, the pick of the week might be Saturday morning (12 September). The swell drops back to a much more manageable 3.3ft from the SSE, period 9 seconds, with a light S breeze at 6 mph keeping it clean. The energy is moderate (351), and the conditions are described as “good surf conditions.” Not a huge day, but clean and user-friendly. Sunday morning (13 September) is also a real standout – glassy conditions with the wind going dead from the ESE at just 3 mph, wave height around 3.3ft from the SE, period 9 seconds. If you want smooth, lined-up walls, that’s your window. The only caveat: Trapdoors can be inconsistent, so don’t expect a non-stop conveyor belt.

After that, we hit a flat, poor spell. From Monday (14 September) through to about Wednesday morning (16 September), the swell bottoms out to 1.3ft and the wind goes onshore or cross-on. It’s basically a dead zone for nearly three days. Not worth paddling out.

We get a brief pulse Wednesday morning (16 September) with 5.2ft from the SE, period 8 seconds, and a light cross-off SSE wind at 6 mph. The energy is moderate at 388, and it’s labeled as “good surf conditions.” That’s a sneaky good session for the more experienced, but the short period (8 seconds) means it'll be a bit softer and less pushy.

After that, it’s mostly weak and onshore for the rest of the forecast window. Some interesting notes for the very long-range: Saturday morning (19 September) shows a tiny 1.6ft swell, but get this – the period is 18 seconds! That’s a very long period groundswell, which at a point break like Trapdoors can produce some surprising, clean lines if it lines up. The wind will be glassy too (ESE 3 mph). It’s not big, but for the patient surfer, it could offer some of the best-shaped, most glidey waves of the whole outlook, albeit small. Similarly, Sunday morning (20 September) has 2.0ft with a 13-second period and glassy ENE wind. These long-distance swells are promising, but with such small heights, it’s a roll of the dice. Don’t go out expecting a classic session.

In short: the standout is Thursday/Friday for the advanced crew looking for size and power (8.2ft, strong energy). For cleaner, more manageable waves, aim for Saturday morning (12 September) or that glassy Sunday morning (13 September). The second week looks mostly flat or mediocre, with only that tiny, long-period Saturday (19 September) as a potential dark horse. Stay sharp, and I’ll catch you in the water.
