Table - best surf conditions forecast for Big Ben over the next 16 days.


Alright, let’s get into it. Right now, the surf at Big Ben is pretty average, but there are a few windows of clean conditions that are worth a look.

The water temperature is sitting at 76°, which is about normal for this time of year, so no need to dig out the steamer.

Sunday the 12th is a bit of a write-off – we’ve got a solid 8ft SSW swell pushing in with a long 16-second period, so there’s plenty of energy (3049), but the wind is cross and bumpy. That’s a lot of water moving around with a chop on it, not great for a clean ride. It’s more of a challenge than a pleasure.

Monday morning the 13th is where it gets interesting. The swell drops to a more manageable 4ft from the SW, with a 13-second period, and the wind goes glassy – dead calm. That’s the kind of morning you set an alarm for. The energy is moderate (582), but with zero wind, those waves are going to be clean and smooth. This is the standout of the forecast period.

Tuesday the 14th morning also has glassy conditions, but the swell is down to 3ft and energy is low (238). It’ll be small and clean, good for a longboard or a beginner session.

Now, from Wednesday the 15th through to the end of the week, we hit a dry spell. Swell drops below 3ft, winds turn onshore or cross-shore, and the energy readings are all in the low hundreds. There’s nothing worth paddling out for.

We get a little spike again on Saturday the 18th of July – 8ft SE swell with a 12-second period, energy is strong (1955). But the wind is cross-onshore from the east, making it messy. That’s a lot of power but poor quality, and at that size, it’s really only for experienced surfers, and even then the conditions won’t do it justice. Might be more interesting for the kite crew.

The following week stays small and mostly onshore, with a brief glimmer on Tuesday the 21st morning: 4ft from the east, 10-second period, and glassy conditions. Energy is moderate (422). That’s another small, clean window but nothing to get too excited about.

Overall, the best bet is Monday morning the 13th of July – glassy, waist-to-chest high SW swell, and the place to yourself since it’s inconsistent. Crowds are possible here, but on a Monday morning with that forecast, you might get lucky. Just keep an eye on the tide.

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.
