Cardiff Reef Surf Forecast and Surf Report

Alright, this is Rusty. Let’s have a look at what we’ve got lined up for Cardiff Reef over the next couple of weeks. I’ll be straight with you—this stretch doesn’t have any standout days that’ll have you ringing your mates. It’s a very consistent reef break, so it’s not that it won’t break, it’s just that the quality is mostly marginal or poor throughout the whole 16-day window. The swell energy is there, but the conditions are just not clicking.

You’ve got a long-period, deep-water groundswell rolling in from the SSW for most of the period. That long period (over 15 seconds at times) means the waves will have some push and shape, and on a reef like this, that’s actually a decent match. But the problem is the wind. Most days we’re looking at light to moderate onshore breezes, mostly from the W or WSW, which kills the surface. Not a lot of glass out there.

The real kicker is the water temperature. It’s sitting at 76°F, which is a whopping 8°F warmer than average for this time of year in late August. That’s very unusual—you’ll be sweating in your wettie or loving the tropical bath depending on your point of view.

Let’s run through it day by day.

On Friday the 28th of August, we start off. The morning has 0.7m (2 ft) from the SW with a 16-second period. Light WSW breeze, but the forecast says poor surf conditions—score is a 0, so it’s really not worth paddling out. The afternoon gets a tiny bump to 0.8m (3 ft) from the SSW with a very long 19-second period, and the energy jumps to 583 (moderate). But it’s still a marginal call. Probably a surf for the keen, patient local who knows the reef.

Saturday the 29th looks better on paper but still not clean. 1.1m to 1.3m (4 ft to 4 ft) from the SSW, period dropping to 16 seconds, with onshore winds from the WSW and W. Energy hits up to 952 (moderate). But the wind makes it messy. Still, if the tide’s right, the reef might offer a few bowly lefts. Not a standout.

Sunday the 30th is similar—1.1m (4 ft) dropping to 1.0m (3 ft), cross-onshore wind in the morning (SW), which is described as gentle and fairly choppy. Not your best day.

From Monday the 31st of August through Wednesday the 2nd of September, it’s a big slump. Swell drops under 1.0m (3 ft), periods are shorter (11-14 seconds), and the combined energy falls into the 132 to 393 range (weak to moderate). Wind is onshore and light, but the wave quality is rated as poor across the board. Nothing doing.

Thursday the 3rd of September shows a tiny sign of life: 1.1m (4 ft) in the afternoon from the SSW with a 12-second period, energy at 808 (moderate). But again, it’s marginal, and the wind is still onshore from the W. You might snag a rogue set, but don’t expect much.

Friday the 4th of September morning has the best-looking numbers of the whole run: 1.0m (3 ft) from the SSW with a very long 17-second period, energy at 919 (moderate). Light W wind, still onshore. The score only hits a 2 out of 10, which is the highest you’ll see anywhere here. This is the best option of the lot, but that’s not saying much. It’s a reef break, so the long period might line up a few proper walls. If you’re going to pick a session, this Friday morning is it.

After that, Saturday the 5th through the end of the forecast goes back to poor or marginal calls. Swell stays around 0.9m to 1.2m (3 ft to 4 ft), winds stay onshore from the W to WNW, and the energy slowly fades. By the time you hit the second week—September 7th onward—it’s mostly poor, with a few marginal glimmers on Thursday the 10th and Friday the 11th of September when the swell bumps back up to 1.2m (4 ft) and 0.9m (3 ft) with 15-second periods. But the wind never cooperates.

There’s no true standout here. The best on offer is that Friday 4th of September morning. It’s not a barnburner, but it’s the cleanest window with the most energy. Crowds are listed as “sometimes” at Cardiff Reef, so on a marginal morning you might have it mostly to yourself. That’s the silver lining.

Otherwise, you’re looking at a pretty flat and uninspiring 16 days. For once, the consistency of the break doesn’t help because the wind is just onshore too often. It’s not a good run for beginners either—though the swell rarely gets over 1.5m (5 ft), the onshore chop and long-period sets can be tricky. Expert surfers might find a few wedges on that Friday, but honestly, it’s a wait-and-see.
