Chigasaki Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s cut through the noise and have a proper look at what’s on offer for Chigasaki Jetty over the next couple of weeks.

To be honest, the forecast is a bit of a tough one. We’re looking at a long stretch of very ordinary conditions, with the first real glimmer of life not showing up until the second week of September. The water temperature is sitting at 82°F, which is a touch warmer than average for this time of year – nothing crazy, but you’ll notice it’s a little on the balmy side.

We start off on Thursday, 27 August, with a tiny 2ft south swell and a period of just 6 seconds. The morning is glassy though, with a light SSW breeze, so that’s the only saving grace. The combined energy is weak (85), so it’s small, weak, and short period. The afternoon sees the wind swing north and pick up to 12 mph, turning it into a cross-shore mess.

Friday, 28 August, the morning is cleaner with a light cross-offshore breeze, but the swell is still a paltry 2ft (59 energy). The afternoon glass-off shows a slight bump in energy to 115 (moderate), but the swell is still only 3ft and short period. It’s surfable, but “very ordinary” is the phrase.

From Saturday, 29 August, right through to Monday, 7 September, it’s a real grind. Small swells, mostly under 3ft, and a lot of cross-shore or onshore winds. The energy figures are all over the place, but the wave comments are all the same: poor surf conditions. There are some glassy moments here and there, but the swell just isn’t there to back it up. This is a solid week or more of scraps.

Now, we start to see a change around Tuesday, 8 September. The morning brings a 3ft swell from the SSW with a 12-second period, but the wind is a cross-onshore 9 mph, killing the quality. The energy is strong (264), but it’s messy.

The real standout, if you can call it that, is Wednesday, 9 September. The afternoon sees a 8ft swell from the SSW with a 13-second period – that’s proper long-period groundswell. The combined energy is huge (2709). Now, this is a powerful swell, but it’s a beach/jetty setup. Long-period swells this size can be a handful; they’ll be breaking hard and fast, and the sets will be stacked. The wind is a cross-shore 16 mph, so it’s not going to be clean. This is strictly for experts only.

Thursday, 10 September, offers a cleaner morning with a cross-offshore wind, but the swell drops to 5ft (615 energy). The wind is strong at 16 mph, so it’s a bit of a battle.

The rest of the period into the second week continues with moderate to strong energy, but the wind is always a problem – cross-shore, onshore, or just too strong.

The best bet? If you’re an experienced surfer, the afternoon of Wednesday, 9 September, offers the most power. The 8ft SSW groundswell (13 seconds) is the biggest of the forecast. But with that cross-shore wind, it’s going to be a challenge. For the average surfer, there’s really nothing that stands out as a clean, fun session. The early glassy mornings in the first week might give you a dribble, but it’s not worth paddling out for.

Rusty.
