The Lowdown

Alright, Rusty here. Let’s break down the Cobblestones forecast.

We’ve got a solid run of swell, but it’s not all clean. The standout window is definitely the first few days – Wednesday the 22nd through Thursday the 23rd. That’s where the magic is. After that, things get messy with wind, and then we’re looking at some serious size that’s only for the brave.

Wednesday 22nd July kicks it off with a solid 11.5 ft SW groundswell. The period is a long 15 seconds, so there’s a heap of energy in the water – you can feel it in the combined energy reading (5896). That’s strong, powerful stuff. The wind is a light cross-offshore from the E at 6 mph, keeping it clean. This is expert territory at that size, no question. The water temp is about average for this time of year, so no surprises there. The afternoon holds similar size at 11.5 ft, dropping a touch to a 14-second period, but the wind swings SE at 9 mph, still cross-off. It’s still excellent, just a fraction less perfect than the morning.

Thursday 23rd July is another beauty. The morning brings an 8.2 ft SW groundswell with a 14-second period, but the wind is a clean offshore from the NE at 9 mph. That’s a major positive. The combined energy is still a strong 2893. The afternoon is the real gem though – glassy conditions with NNE wind at just 3 mph. The swell is 7.9 ft from the SW, 14-second period, and the energy is 2125. This is as clean as it gets. For experienced surfers, this is the pick of the week.

Friday 24th July sees the swell drop to 5.6 ft in the morning, with a 12-second period. The wind is cross-off from the NNE at 12 mph, so it’s still clean, but the energy is dropping (964). The afternoon is a bit better at 5.2 ft, and the wind eases to 9 mph. It’s surfable, but nothing special.

Saturday 25th July is a write-off. The morning has a 5.6 ft WSW swell, but the wind is a fresh 19 mph from the NNW, making it cross-off and clean in the morning, but it’s only marginal. The afternoon gets ugly – 22 mph cross-shore wind makes it lumpy and poor. Don’t bother.

Sunday 26th July is a no-go. Onshore gales with 31 mph winds and 14.8 ft+ swell. That’s a hard pass. The energy is massive (5201+), but the wind ruins it completely.

Monday 27th July is a bit of a recovery. The swell is still solid at 9.8 ft to 11.5 ft from the SW, with a 13-15 second period. The wind is a gentle cross-off from the SE at 9 mph, keeping it clean. The combined energy is strong (3527 to 4746). The forecast is marginal, likely due to the size, but for experienced surfers, it’s still worth a look if you can handle the juice.

Tuesday 28th July is another good day. The morning has a 9.8 ft SW swell, 14-second period, with a moderate offshore wind from the NE (12 mph). The energy is 3505. The afternoon is a bit smaller at 8.2 ft, with a light cross-off breeze. Clean and powerful.

From Wednesday 29th July onwards, the wind starts to flip. The swell hangs around, but the wind turns cross-on or onshore. The 29th has a very long period (17 seconds) 4.6 ft to 6.9 ft swell, but it’s a bit messy. The 30th and 31st are blown out with strong cross-onshore winds. August 1st is a stormy mess.

Sunday 2nd August is a massive outlier. The forecast is for a 24.6 ft WSW swell with a 19-second period – that’s a huge, very long-period groundswell. The combined energy is off the charts at 73367. The wind is onshore, but the report says it’s too big for the break anyway. This is an absolute monster, experts only, and even then, it’s a maybe. The swell is so big (over 8.2 ft) that it’s simply not for the average surfer.

The Rest of the Week (3rd to 6th August): The wind stays onshore or cross-onshore, and the swell remains above 13 ft most days. It’s messy, big, and dangerous. Not worth the paddle.

So, the best on offer is the Thursday 23rd July afternoon session at Cobblestones. You’ve got a 7.9 ft SW groundswell, 14-second period, a good 2125 energy, and glassy conditions. That’s a dream. For a close second, the Wednesday 22nd July morning is a massive, powerful 11.5 ft swell with clean cross-off wind, but it’s for the experts. The crowds at Cobblestones are ‘sometimes’ an issue, so you might get a few out, but with that quality, it’s worth

Information about the Cobblestones Surf forecast

The above surf forecast table for Cobblestones provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cobblestones can be found by selecting the local surf guide option on the grey menu. Our Cobblestones surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Cobblestones) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Cobblestones may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
