Alright, Rusty here. Let’s have a look at the only game in town for the next couple of weeks.

So, Big Ben is the only spot on the radar, and the next 16 days are a bit of a mixed bag. It’s an exposed beach-and-jetty setup that’s inconsistent, which is pretty normal for the area. The water’s sitting at about 76°, pretty much where it should be for this time of year – no nasty surprises there.

The opening stretch is lackluster. Monday the 13th serves up a bumpy 5ft SSW swell with a medium-period groundswell of 13 seconds, but it’s coming with a cross-shore breeze and the energy is moderate (763). Not really worth paddling out for anything special. Tuesday the 14th gives you a bit of a rest, with a glassy 3ft SSW swell in the morning (239 energy), but it’s small.

Wednesday through to Saturday morning are a write-off: small, choppy, crossed-up, or onshore. The swell drops to 2-3ft, and the wind just ruins it. Sunday the 19th morning cleans up a touch with a cross-offshore NNE breeze and a 4ft E swell (354), but it’s marginal at best.

The first real highlight doesn't come till Wednesday the 22nd of July. That morning you’ve got glassy conditions, just about perfect. The swell is a solid 8ft ENE groundswell with a long 11-second period, and the combined energy is strong at 1283. It’s a bit heavy for beginners – over 8ft is expert territory, and at 8ft it’s pushing into experienced-only zone. This is the best on offer, but it’s a long-range call, so don’t lock it in just yet. For an inconsistent spot like Big Ben, if you’re intermediate or above, that Wednesday morning session looks like the one to circle.

After that, the swell backs off through the end of the month. Thursday the 23rd is smaller with onshore wind. Friday the 24th is small and choppy. Saturday the 25th morning looks tidy again with a cross-offshore N breeze and a clean 3ft SE swell (208), but it’s tiny. The final few days into the 28th get messy with fresh to strong cross-shore breezes and lumpy conditions. The swell stays in the 4-6ft range with moderate energy, but the wind just kills it for a paddle session.

So, to call it: the standout is Wednesday morning, July 22nd. Glassy, solid swell, but it’s for the experienced crew. The rest is mostly small, choppy, or waiting on a clean window that might not open.

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.
