Cobblestones Surf Forecast and Surf Report

Alright, Rusty here. Let’s have an honest look at what’s headed our way.

Alright, mate. The next two weeks are a bit of a wild ride for Cobblestones. That spot is a real challenge, only for the experienced crew, and it needs a clean window to be worth the paddle. We’ve got a huge pulse coming in first thing, but the wind is going to spoil a lot of it. The real standout is a very glassy session on Friday the 21st of August, and then the whole second week looks pretty average to ugly. There’s a long gap of nothing much worthwhile after Sunday the 23rd.

It all kicks off Saturday the 15th of August. An afternoon session shows a solid 8ft WSW groundswell with a 13-second period—that’s proper energy (2116). The water is 66°, about a degree and a half warmer than usual, so it’s a touch warmer than normal. A 15 km/h NNE wind is keeping it cross-off and clean. Excellent conditions for an experienced surfer. This is the pick of the first few days, no doubt.

Sunday the 16th has a bigger 10ft WSW swell, but there’s a fresh breeze at 30 km/h. The morning and afternoon are both just “questionable” and only worth a 3. It’s a step down.

Monday the 17th is a mess and a washout. Heavy rain, then showers, with a 45 km/h onshore wind. The swell jumps to 15ft then 16ft—that’s way too big for anyone but experts, and with the wind howling onshore, it’s unsurfable. A kiter might have a ball, but not for a surfer.

Tuesday the 18th and Wednesday the 19th stay big with 13ft to 15ft WSW swell, but the wind is cross-onshore. A few of the afternoon slots are “fairly choppy” but might be just about rideable for the brave. Nothing special.

Thursday the 20th is more messy onshore wind and big swell. Skip it.

Now, the absolute standout. Friday the 21st of August. The morning is clean with a cross-off breeze and a 13ft SW groundswell. But it’s the *afternoon* that’s the gem: glassy conditions, a 5 km/h SE breeze, and a 13ft SW groundswell with a 14-second period (6472). This is exceptional for experts. That’s the one to circle on the calendar.

Saturday the 22nd has two excellent windows. A 10ft SW swell in the morning with a light cross-off breeze. The afternoon is glassy again with a lighter 8ft SW swell. Both are clean and good for experienced paddlers.

Sunday the 23rd is okay in the morning, a clean 8ft SW swell with a long 15-second period, but the afternoon gets lumpy cross-shore wind. From here, it’s all downhill.

Monday the 24th through Wednesday the 27th sees dropping swell but increasingly strong and ugly wind. The sessions are all marginal to poor. By Tuesday the 25th, it’s 5ft to 6ft with a near-gale and strong cross-onshore wind. Then Wednesday the 26th, a massive 15ft pulse hits with a fresh onshore gale—again, unsurfable, possibly more for kites.

Thursday the 27th to Sunday the 30th is a rough end. The swell stays big, from 10ft to 13ft, with onshore or strong cross-onshore winds. The last session on Sunday the 30th has a massive 13ft, 18-second groundswell (15896!), but a 15 km/h onshore wind makes it just too big for the spot. A real shame.

So, the bottom line: the first couple of days have their moments, with Friday the 21st’s glassy afternoon being the epic window. After Sunday the 23rd, the run looks pretty grim for a solid week. For the area, a blank run like this isn’t unusual when the wind turns sour.

Rusty.
