The Lowdown

Right then, let’s have a look at what we’ve got. To be honest, the next couple of weeks are a bit of a slow burn. The first week is pretty quiet, with just tiny waves and not much to get excited about. But hold on, because the second week starts to show some real promise, and there’s a couple of sessions that’ll be well worth the wait.

We’re talking about Big Beach. Water temp is sitting around 80°, which is pretty normal for this time of year, so no nasty surprises there.

The early part of the run, from Saturday the 1st through to Sunday the 9th, is mostly small and weak. Swell heights are hovering between 1ft and 2ft, with the odd pulse. Most days are a cross-off breeze, so it’s clean but the wave energy is low, often in the ‘weak’ bracket (74 to 191). A few sessions, like Monday the 3rd afternoon and Tuesday the 4th, see a little offshore wind and a touch more energy (103 to 117), but it’s still only surfable in a very ordinary way.

Things start to shift around Monday the 10th. The swell picks up to 2ft to 3ft from the SSW, with a nice 15 to 16-second period. The energy jumps into the solid ‘moderate’ range, hitting 403 on Monday afternoon. And the wind? Gentle offshore from the NE through to Tuesday. This is the first real standout. Clean, lined-up waves with enough push to be fun. Not big, but quality.

Then from Wednesday the 12th onward, it gets even better. The swell builds through the week, reaching 4ft from the S by Thursday the 13th. The combined energy climbs strongly, hitting 767 on Wednesday morning and peaking at 892 on Friday the 14th afternoon. That’s proper energy. Periods are around 15 to 18 seconds, which is long-period groundswell. This will wrap in nicely, though at a beach break it might be a little straight on the sets. The wind is offshore or gentle cross-off all through this window.

The real standout is Thursday the 13th through Saturday the 15th. On Thursday the 13th, you’ve got 4ft of S swell with a 16-second period, offshore wind, and energy readings over 700. That’s very good surf, clean and punchy. Friday the 14th afternoon is similar, with 4ft S swell, offshore NE wind at 15 mph, and energy at 892. Then Saturday the 15th keeps it going at 3ft with 15 second period and gentle offshore wind. These are your best shots. Just be aware, with that consistency rating, Big Beach is a very consistent spot, and crowds are sometimes a factor, so expect company.

For beginners, the swell in that second week gets up to 4ft which is getting a little too much. For experienced surfers, it’s prime. Anyone on a longboard or mid-length will have a ball on that morning glass on the 10th and 11th.

Signing off, Rusty.

Information about the Big Beach Surf forecast

The above surf forecast table for Big Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Beach can be found by selecting the local surf guide option on the grey menu. Our Big Beach 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 Beach) 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 Beach 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.
