The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s coming our way over the next couple of weeks. It’s a bit of a mixed bag with a heck of a lot of waiting, but there are a couple of sessions that might just make it worth hanging onto your board.

The Overall Pattern
Right off the bat, we’re in a pretty quiet spell. The first real recommendation doesn’t pop up until Tuesday, July 14th, and even then it’s a narrow window. Most of the 16-day run is plagued by poor conditions—cross-shore and cross-onshore winds, choppy surfaces, and waves that just aren’t cleaning up. There’s a big gap of nothing much from July 14th afternoon all the way through to July 19th morning. After that, we get a glassy moment on the 20th, then another long stretch of messy, poor-quality surf until the very end of the forecast. The standout is a sneaky clean session on Tuesday, July 28th morning.

The Detail, Day by Day

Tuesday, July 14th – Morning Only
We kick off with a small, clean window at Big Ben (beach/jetty) . The morning serves up some clouds, but the wind is glassy at 3 mph from the SE, which is a real treat. The swell is 3 ft from the SSW with a period of 11 seconds and a combined energy of (238). It’s weak but it’s clean, and the water temp is about average for the time of year. This is a beginner-friendly spot, and it’s inconsistent, so you’ll have to work for your waves, but it’s the best of the early days. The afternoon goes south fast with a cross-shore wind, so don’t sleep in.

Wednesday, July 15th – Sunday, July 19th
This is a rough patch. From the 15th through the 19th, the wind is either cross, cross-on, or onshore, with speeds picking up to 9-12 mph. The swell stays tiny—2 ft to 3 ft—with a short period (8-9 seconds) and low energy (124 to 271). The water is a mess of chop and wind ripples. The surf is poor, and honestly, not worth paddling out for. The 19th shows a glimmer of “marginal” conditions, but it’s still cross-on, so I’d skip it.

Monday, July 20th – Morning Only
Another one-morning wonder. The 20th starts with glassy winds from the S at 3 mph, and we get 4 ft of swell from the E with an 8-second period and energy of (207). The waves are small and a bit weak, but the surface is clean. The afternoon turns cross-on again, so get your session in early.

Tuesday, July 21st – Thursday, July 24th
The swell picks up a bit on the 21st morning, with 5 ft from the E, a 10-second period, and a much stronger energy of (464). But the wind is cross-on, so it’s choppy and only marginal. The following days are all cross-on or cross-shore, with the swell dropping back to 3 ft-4 ft, and the energy is moderate (274-334). The wind is never clean, and the wave conditions are poor. The 24th morning is glassy with only 2 ft, but it’s too weak to get excited about.

The Standout – Tuesday, July 28th Morning
This is the one to circle on your calendar. Big Ben wakes up to some clouds, but the wind is a clean cross-offshore from the NE at 9 mph. The swell is 4 ft coming from the S with an 11-second period and a very solid energy of (494). The water is clean, and the conditions are good. This is easily the best-looking session of the whole 16 days. The crowd profile says “sometimes” busy, so you might have a few others in the water, but the quality should be worth it. The afternoon goes cross-on, so it’s a morning-only affair.

Wednesday, July 29th – End
The last day in the forecast fades back to small, cross-shore conditions with 2 ft from the S and energy of (215). Back to the bench.

Final Word
It’s a tough run for consistency, but keep your eyes on Tuesday, July 28th morning. That’s your best bet for a clean, punchy session. The rest of the time, you’ll be fighting the wind or waiting for a glass-off that rarely comes. Hang in there.

Rusty.

Information about the Big Ben Surf forecast

The above surf forecast table for Big Ben provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Ben can be found by selecting the local surf guide option on the grey menu. Our Big Ben 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 (Big Ben) 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 Big Ben 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.
