The Lowdown

G’day, Rusty here. Let’s get straight into it. The next 16 days are a real mixed bag for Middleton Beach, a real tale of two halves. The start is a bit of a dud with small, weak swell and iffy winds, but the back half of the week has some proper size and clean conditions that will have the crew out. The thing is, this spot is a sheltered one, so the swell needs to be coming from the southwest to really wrap in. When it’s on, it’s on, but the wait can be a long one.

First up, Sunday the 16th sees a bit of swell around 8ft from the southwest, but a morning north wind kicks up a cross-off breeze. The energy is moderate at 2868, but the conditions are only marginal. The sea temp is sitting at 64°F, which is a touch warmer than usual for this time of year, but it's nothing to get too excited about. That afternoon the wind goes light cross, and the waves drop slightly to 7ft, but it's a bit scratchy.

Monday the 17th is better. The wind howls from the north in the morning at 25 mph, which makes a mess of things and it's not worth it. But the afternoon, a fresh west-northwest breeze swings offshore, and the swell holds at 8ft with a long 17-second period. The energy builds to a strong 4347. That’s a decent window with cleaner lines. Tuesday the 18th looks like the first real standout. Clean, offshore west winds all day, 8ft of southwest groundswell with a 15-16 second period, and moderate to strong energy around 3413 to 3555. A very good day.

Wednesday the 19th is a big one. The morning is okay with a cross-off breeze, but the afternoon turns it on. The swell jumps to 12ft with strong energy at 5437. The wind goes light and offshore, making for excellent, powerful waves. This is getting into expert territory, so the beginners should stay on the sand. Thursday the 20th keeps the size at 10ft, but a fresh offshore wind makes it clean in the morning, with energy at 5756. The afternoon turns cross-off and the conditions get a bit more challenging.

Now for the standout of the whole run. Friday the 21st, early morning. The swell peaks at 13ft from the south-southwest with a 17-second period and energy reading a massive 10024. The wind is dead glassy, just a slight air. This is as good as it gets, big, clean, powerful groundswell. It will be a circus out there, but for the experienced crew, this is the session. The afternoon will see the wind go cross-on and the size will start to fade, so get it while it’s good.

The weekend of the 22nd and 23rd sees the swell drop back to 8ft but with clean conditions on Saturday. The 23rd is a write-off with strong onshore easterly winds and rain showers, so that’s a no-go.

Then we get a lull. Monday the 24th is small, under 4ft, and not worth the paddle. The energy is weak at 1104 to 1279. The rest of the week stays small and tricky. Tuesday the 25th has a lot of wind and a long period swell, but it’s hard to get into. From the 26th onward, the size comes back up to 12ft on Wednesday, but the wind is fresh and cross-off, making it a bumpy ride.

The second week from around the 25th onwards is less certain, but it looks like there’s another pulse coming in. The 26th has 12ft from the southwest, but the wind is up. The 27th looks cleaner, with 7ft and light winds, but the energy is only moderate. The 28th and 29th hold around 8-8ft with moderate energy, but the wind is fresher. By the 30th, we’re looking at smaller, weaker surf, and the run ends with some pretty ordinary 4ft waves and light onshore breezes on the 31st. The energy has gone out of it by then.

So, to sum it up: the best of the bunch is Friday the 21st for the big, glassy, powerful swell. If that’s too much, Tuesday the 18th is your pick with clean, solid waves. The rest is either too small, too windy, or too messy. It’s a patchy outlook, but those two days are worth circling on the calendar.

Information about the Middleton Beach Surf forecast

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