Uchizuma Surf Forecast and Surf Report

Alright, mate, Rusty here. Let’s have a look at what’s on the cards for Uchizuma.

First thing to say – the water is sitting at 84°F, which is about 2°F warmer than usual for this time of year. Not crazy, but definitely noticeable – you’ll feel that extra warmth paddling out.

The big news is that we’ve got a massive pulse of energy coming in on Tuesday morning, the 25th of August. The combined energy is a whopping 4834 – that’s serious, strong energy. We’re looking at a 10ft swell from the SSE with a 14-second period. That’s a long-period groundswell, which means powerful, well-shaped waves, but the sets will be a bit more spaced out. For a spot like Uchizuma, which is fairly exposed to swell, this is a lot of water. The wind is a light 6 mph from the S, so it’s a cross-on breeze – not ideal, but light enough that it’s not wrecking it completely. However, with 10ft, this is firmly in the expert-only zone. Beginners, stay well clear. The downside is the tide conditions are questionable, and the overall quality is marginal. It’s the biggest swell of the whole period, but not the cleanest.

By Tuesday afternoon, the swell drops to 8ft, still from the SSE, but the wind picks up to 9 mph onshore, and the energy is still very strong at 3331. The quality drops off fast – it’s pretty ordinary.

Wednesday morning, the 26th, sees the swell down to 6ft from the S, period 12 seconds, energy at 1295. Still moderate-to-strong energy, but the wind is cross-on at 6 mph, and the conditions are described as marginal. It’s not going to be a session to write home about.

After that, things go south in a hurry. From Wednesday afternoon all the way through to the end of August, we’ve got a run of poor to very ordinary surf. The wind is mostly cross-on or onshore, and the swell drops to under 4ft with short periods around 8 seconds. The energy falls into the weak range – under 100 for most of it. There’s a brief glassy window on Friday morning, the 28th, but the swell is only 4ft from the S with an 8-second period, and the energy is just 224. It’s surfable, but very ordinary. The same goes for Saturday morning, the 29th – glassy, but the swell is tiny at 2ft (energy 81). Not worth paddling out for.

We hit a real flat spell from the 31st of August through the 1st of September. Swell under 3ft, weak energy, and the wind is mostly onshore or cross-on. It’s a dead period.

Then, on the 2nd of September, we get another pulse of energy. Wednesday morning shows 8ft from the SE, period 10 seconds, energy at 1704 – that’s strong. But the wind is a solid 16 mph cross-on, and it’s described as poor surf conditions, with choppy water. That’s more of a kite-surfing setup than a clean paddle session. The same goes for the afternoon and into Thursday, the 3rd, when the wind hits 25 mph from the SE with moderate rain. The swell is still 7ft, but it’s blown out.

The one real standout in the whole 16-day window comes on Sunday morning, the 6th of September. The swell is only 3ft from the SSW, but the period is a nice 12 seconds, and the combined energy is 333 – moderate. What makes it special is the wind: 6 mph from the NE, which is cross-offshore. That’s clean, glassy conditions, perfect for a spot like Uchizuma. The waves will be small but well-shaped, and with that offshore breeze, you’ll get some nice lines. The crowd situation is “sometimes,” so you might have a few others out, but it’s not a circus. This is the best bet for a decent, clean session over the whole period.

Monday morning, the 7th, and Tuesday morning, the 8th, also have some promise with cross-offshore winds and clean conditions, but the swell is small (3ft to 4ft) and the period is shorter (9-10 seconds). The energy is moderate. Tuesday afternoon, the 8th, sees a bigger 5ft swell from the ESE, but the period is a short 6 seconds – that’s windswell, so it’ll be a bit junky, but the wind is cross-offshore and clean.

So, to sum it up: the first week is a mixed bag with a huge, powerful swell on the 25th that’s for experts only, then a long, flat, messy run. The real gem is the morning of the 6th of September – small but clean, and the best chance of a fun, uncrowded surf. Keep an eye on the 8th as well for a possible fun session.

Rusty.
