G'day, Rusty here. Let's look at what's cooking for Big Ben. Water temp is 73°F, which is a bit cooler than average for the season - nothing wild, but you'll feel it.
The surf starts Tuesday, July 7th, with a 6ft SE swell, 15-second period, and combined energy at 1367. Wind is cross-shore, and it's looking marginal with a bit of chop. Not a great way to kick things off.
Wednesday the 8th picks up. Swell hits 7ft from the SSE with a very long 16-second period, and energy jumps to 2431. Light cross-on wind keeps it rideable, though not glassy. This is the best morning of the early run. The afternoon drops to 7ft, still solid.
Thursday the 9th is 6ft SSE swell, 14-second period, energy at 2029. Light cross-on again. Friday the 10th sees 6ft building to 7ft from the south, period hitting 16 seconds, and energy up to 3071. The afternoon gets a little choppy with that gentle breeze.
Saturday the 11th is a big one: 8ft from the SSW, 16-second period, and strong energy at 3436. That's expert territory. Wind goes moderate cross-on, so it'll be choppy. Sunday the 12th is 7ft, still cross-shore wind.
From Monday the 13th, it dies. Swell drops to 4ft, energy down to 538. We've got a quiet spell through to about Friday the 17th, with tiny, weak waves and messy wind. Normal for the area.
Saturday the 18th of July afternoon shows a pulse: 7ft from the ESE, short 10-second period, energy at 1105. Light cross-on wind. Then Sunday the 19th morning is the standout: 8ft from the south, 14-second period, and energy of 3771. Light cross-on wind - that'll be clean and solid.
Monday the 20th of July morning is massive: 10ft from the east, 10-second period, and energy at 4313. But the comment says it's too big for this break. Experts only, and even then, it'll be heavy and messy. The afternoon settles to 8ft.
After that, the surf fades again with small, weak waves through to the end.
Best call: Wednesday the 8th of July morning. 7ft of SSE groundswell, very long period, and light enough wind for decent waves. Sunday the 19th morning is a close second, but it's further out.
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.
