Number Fours Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Number Fours has in store for us.

The next 16 days are a bit of a mixed bag at Number Fours. We’re looking at a long stretch of so-so conditions, where the wind is mostly cross-offshore from the ENE, but the main issue is that it’s just too blustery to get clean, workable lines for most of the period. The water temp is sitting at 81°, which is pretty much normal for this time of year, so no surprises there.

We kick off on Tuesday, 1st September, with a 6ft ENE swell, but it’s short-period at 8 seconds and the wind is a fresh 19 mph cross-off. The energy is weak (841), so it’s not really doing much. The morning is a bit more promising than the afternoon, but it’s still marginal. Wednesday and Thursday are more of the same—the swell builds to 7ft, but the wind picks up to 25 mph, making it a messy, blown-out affair. The energy is moderate (up to 1363), but with that wind, it’s not going to be a fun paddle.

The first real standout comes on Saturday, 5th September. The swell drops slightly to 7ft, but the period jumps to 13 seconds—that’s proper groundswell energy. The wind eases to 19 mph, and the energy is strong (2063). This is a big blob of power, but those long-period swells can be a bit tricky at a reef break like Number Fours, making the waves a bit too straight. Still, if you’re an intermediate, this is the best of the first week. Sunday, 6th September, is similar but with a touch less wind at 16 mph—very clean, but still those long-period lines.

The 8th of September brings a weird shift: a 5ft SSW swell from the south with a very long 15-second period. The energy is still strong (2210), but the wind is a light cross-shore from the ESE. That’s a tricky combo for this break, and the wave comment mentions it’s marginal. Not a standout.

The real wall of water arrives on Friday, 11th September, through to Saturday, 12th September. Friday morning sees 10ft ENE swell, building to 12ft by afternoon, with a moderate 12 mph cross-off. The energy is strong (2411). Saturday, 12th September, is the peak: 13ft of ENE swell with a 10-second period, and only 9-12 mph offshore winds. The energy is very strong (4164). This is only for experts—over 8ft is serious business. If you’re skilled and hungry, Saturday morning looks like the best session of the whole outlook, with clean, powerful waves. After that, it all drops off a cliff. From Sunday, 13th September, onward, the swell collapses to 2ft or less, with weak energy (below 150), and it’s flat and poor for the rest of the window.

So, the pick of the litter is Saturday, 12th September, with that 13ft ENE swell and clean winds. The earlier Saturday, 5th September, is a decent second option for those who want a solid but not life-threatening session. If you’re not an expert, stay away from the 12th.

Rusty, signing off.
