Choshi Surf Forecast and Surf Report

Alright, this is Rusty comin’ at ya from the Choshi area. Let’s be straight with you – the start of this forecast window is a bit of a non-event. The first record we’re looking at is Friday morning, and honestly, there’s nothing to write home about. We’ve got a tiny 1.0ft swell rolling in from the East with weak energy, and the wind’s blowing cross-onshore. It’s pretty meager. The water's sittin' at 76°, which is a touch colder than average for this time of year, so bring a thicker suit if you're gettin' in, but right now it’s not really worth it.

Saturday morning on August 1st, things perk up just a notch. The sea turns glassy, dead calm wind from ESE, and that tiny swell is still only 1.0ft, but the period jumps to a long 18 seconds. The combined energy climbs to a moderate 115. It's not gonna be big, but those long-period lines might offer something small and clean for a patient surfer on a log. The wind is the major positive here – glassy conditions are a gift.

Sunday the 2nd of August is where it starts to get more interesting. We get a jump in size to 4ft from the ESE with a nice long period of 16 seconds. The morning shows a cross-off wind from the NNE – clean conditions. The combined energy is a strong 803. This is the first real highlight. Choshi is inconsistent, and it’s an exposed break, so it needs the right angle. The swell is coming from the ESE, which is a decent match. The crowds can be a thing here sometimes, so be ready for a few heads. This Sunday morning session is the standout early in the period.

Monday the 3rd sees even more power, with the swell hitting 6ft and combined energy surging to 2082. The wind holds clean and cross-off in the morning. This is solid, but it’s getting punchy. By Tuesday the 4th and Wednesday the 5th, the swell just hammers the coast. We’re looking at 10ft to 12ft from the ESE and SE, with combined energy readings over 6000 – that’s strong-to-very-strong energy. The wind is clean and cross-off, and tide conditions look good. However, at this size, Choshi is really only for expert surfers. Anything over 8ft here is a big, powerful beast, and with that long period (15-17 seconds groundswell), the waves are gonna have serious punch. This is too big for beginners and intermediates – it’s a heavy, expert-only zone.

After that peak, the swell eases but remains jumbled for a few days. Thursday the 6th and Friday the 7th of August drop back into the 4ft to 8ft range, but the winds turn more onshore, creating bumpy and choppy conditions.

We then hit a gap. From Saturday the 8th through to Wednesday the 12th, conditions are mostly marginal, with onshore and cross-shore winds and variable swell heights. There’s nothing surfable worth recommending during that stretch.

Then we get a true late bloomer. Thursday the 13th of August morning. Look at this: 5ft of swell from the East, clean with a 13-second period, combined energy of 1167, and glassy winds from the South. This is excellent for experienced surfers. The setup is clean, the swell is solid but not crazy, and it’s a beautiful morning. This Thursday is the other standout on the whole forecast. The afternoon turns onshore and choppy again, so get it early.

The final few days of the outlook, August 14th and 15th, see the swell rising again with onshore wind patterns and some big numbers showing up (over 8ft on the 15th), but the winds are cross-on or onshore, making it messy or too big. So, to sum up: don’t bother with the first couple days unless you’re desperate for a tiny glassy wave. Your best windows are Sunday morning the 2nd of August for a clean, mid-range swell, and Thursday morning the 13th of August for cleaner conditions and a solid wave for those with experience.

Rusty.
