Alright, Rusty here. Let's take a look at what's cookin' at Big Ben for the next 16 days.

Right off the bat, the first few days are a mixed bag. Monday the 13th kicks off with some real promise; we’ve got a clean 5-foot swell from the SSW with glassy conditions in the morning – that’s your window for a sesh. The water temp is sitting at 76°, which is pretty much spot on for this time of year, so nothin’ to worry about there. The wave energy is solidly moderate at (763) and the period is a nice 13 seconds, meaning those lines will have some push and shape. The afternoon holds okay too, just a little smaller at 4 feet with a light cross-off wind.

Tuesday the 14th starts with some glassy 3-foot surf, but it's small and backing off fast. By afternoon it's getting choppy with stronger cross-onshore wind, so put that pen down. From Wednesday the 15th all the way through to Sunday the 20th, it's a real quiet patch. The swell drops right off, energy readings are weak (under 200 for much of it) and the wind is mostly cross to onshore. There’s no real stand-out in that stretch for a proper surf; you’d be fighting chop and weak lines.

Now, here’s where it gets interesting. We’ve gotta look ahead to the next week. Hold on to your board for the morning of Wednesday, 22nd July. This is the standout of the whole outlook. The swell builds to a clean 8 feet from the east with a 12-second period, producing a strong (1538) energy reading. The wind is a light cross-off from the NNE, so those waves will be holding their shape clean. That's a bit on the bigger side – it'll be more for the experienced crew, not a beginner's party. The energy is strong, and the direction is straight out of the optimum SE sweet spot for this spot, so the reef/jetty setup should be cooking.

Thursday the 23rd is still worth a look if you missed the main event. The morning has a good 5-foot east swell with clean cross-off winds and moderate (479) energy. After that, the weekend of the 26th and 27th sees a bit more life returning, with small glassy morning waves around 4 feet on Monday the 27th, but it’s more of a small-wave glass-off than a proper standout. The long period (15 seconds) on that Sunday the 26th could be interesting for the point, but the swell height is tiny at 1 feet.

So, to wrap it up: the next few days have a quick Monday morning window, but the real deal is that Wednesday the 22nd morning. Mark it down, but at a week and a half out, don't hold me to the exact details – forecasts can wiggle. The long dry spell in the middle of the outlook is a bummer, but it picks up again towards the end of the month.

Rusty, signing off.

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.
