Alright, this is Rusty. Let's get into it.

Lookin' at the next 16 days for Big Ben, and honestly, it's a bit of a mixed bag. We've got some serious pulse of energy on the way, but the wind is gonna be a constant battle. The water temp is about what you'd expect for this time of year, nothing out of the ordinary.

The standout period is the first few days, starting this Sunday, the 12th. That morning, we've got a solid 8ft swell from the SSW, but it's coming in with a 12 mph cross-shore wind from the SW. The energy is huge (2906), a real deep ocean pulse, but those conditions are gonna chop it up. It's a marginal call, not the cleanest. The afternoon stays similar, 7ft and still messy.

Now, Monday the 13th is where it gets interesting. The swell drops a touch to 5ft from the SSW, still a solid size, but the wind swings around to the ESE at only 3 mph and goes glassy. That's the magic word. The wave energy is moderate (853). For a spot like Big Ben that's exposed to the SE, this is your best window. It's gonna be clean, lined up, and a proper session. Just keep in mind this spot is inconsistent, so when it fires, you gotta be on it. The crowds can show up sometimes, but for a morning like that, it's worth the company.

The rest of the first week is a slow fade. Tuesday the 14th drops to under 3ft, and the wind stays light, but the energy is weak. By Wednesday and Thursday, it's all poor conditions with onshore wind. Forget it.

Then we get a little glimpse on Saturday the 18th. The swell builds back up to 8ft from the SSE, with moderate energy (1580), but again, it's onshore. The wind is from the SE, so it's gonna be bumpy and not the best quality. That's expert territory size-wise, but the wind is a killer.

After that, it's a long stretch of small, junk surf. The wind is mostly cross or onshore, and the swell is weak. There's a brief pulse on the 21st with 5ft and a 11-second period, but the wind is cross-shore, making it a bit of a wash.

The very end of the period, Monday the 27th, shows a new pulse of energy from the ESE at 5ft, with a very long 16-second period. The energy is strong (1618). This is a long-range groundswell. That kind of period at a beach/jetty setup can be a bit tricky, often breaking too straight. Plus, the wind is a strong 16 mph cross-shore from the NE, so it's gonna be a wild, choppy one. Only for the hardcore on a big board.

So, for the best on offer, lock in Monday morning the 13th. That's your window for clean, glassy waves. Everything else is a gamble or a struggle.

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.
