The Lowdown

G’day, I’m Rusty, and here’s the surf outlook for Middleton Beach.

We’ve got a solid run of swell coming in, but it’s not for the faint-hearted. The first real action hits Thursday, 20 August, with a big 11.5 ft SW groundswell rolling in at a long 16-second period. The water temp is sitting at 64.2°, which is a touch warmer than usual for this time of year. Thursday morning sees a moderate offshore wind from the W, keeping things clean, but the combined energy is pumping at 5468 – that’s some serious power. This is expert territory only, as the sets are grunty and the period is long, making it best for a point or reef setup. Expect a few more waves in the water on Thursday afternoon, but the wind goes cross-off, so it’s a bit less pristine.

Friday morning, 21 August, is a beauty – 9.8 ft SW swell with a 15-second period, light NW offshore wind, and clean conditions. The energy is still strong (4604), and the water’s glassy. This is one of the standouts: a big, clean groundswell with offshore winds. Beginners should steer clear, but experienced surfers will love it. By Friday afternoon, the wind swings onshore from the ESE, and the swell ticks slightly SSW, so it gets rougher.

Saturday, 22 August, morning offers another solid window: 8.2 ft SW swell, 16-second period, light NW offshore, and clean. The energy is 3639, so still plenty of punch. It’s good for those who can handle it. The afternoon brings cross-off winds from the SW, so it’s not as clean.

Sunday, 23 August, sees a drop in quality. The morning has a 6.6 ft SSW swell, but the wind is cross from the SSW, creating a messy cross-chop. The afternoon is a bit better with a 4.3 ft SW swell and a very long 17-second period, but the wind is cross-off, so it’s marginal.

Monday, 24 August, morning gives a 6.9 ft SW swell with a 14-second period, light W cross-off wind, and clean conditions. The energy is 2300, so a moderate, fun-sized swell. The afternoon is a gem: 5.9 ft SW swell, 13-second period, and glassy conditions with SSE wind. That’s a real treat for cleaner waves, though the energy is lower at 1504.

Tuesday, 25 August, morning has a small 3.6 ft SW swell – pretty ordinary. But Tuesday afternoon bounces back with a 7.5 ft SW swell, 12-second period, light NW offshore, and clean. The energy is up to 2302, so it’s a solid session.

Wednesday, 26 August, morning is another standout: 9.8 ft SW swell, 16-second period, WNW offshore wind, and the energy jumps to 7093 – that’s massive. This is for experts only, with long-period groundswell and a moderate offshore breeze. The afternoon sees 11.5 ft SW swell with a 17-second period, but the wind picks up to 30 km/h from the WSW, making it cross-off and a bit gnarly.

There’s a rough patch from Thursday, 27 August, to Friday, 28 August, with strong to fresh winds, messy conditions, and poor surf. Thursday morning has 11.5 ft SSW swell, but 40 km/h cross-off winds make it marginal. By Thursday afternoon, it’s a 11.5 ft SSW swell with 40 km/h cross winds and a risk of thunderstorms – a total mess. Friday, 28 August, drops to 5.2 ft SW swell with 45 km/h winds, so it’s hopeless for paddle surfing; this setup looks more interesting for kite surfing.

Saturday, 29 August, morning picks up a 4.9 ft SW swell with a very long 21-second period – super long period, but the wind is 25 km/h cross-off, so it’s marginal. The energy is 2539, but that long period might make it break too straight at the beach. The afternoon is similar with 5.2 ft SW swell and 19-second period.

Sunday, 30 August, offers 6.6 ft SW swell with an 18-second period, cross-off wind from the SW at 30 km/h, but it’s clean. The afternoon is 6.2 ft SW swell with a 17-second period, moderate cross-off wind.

Monday, 31 August, is a good one: 6.9 ft SW swell, 15-second period, light NNW wind, cross-off, and clean. The energy is 2200, and the afternoon is similar with 6.2 ft SW swell and 16-second period. This is a solid, consistent day.

Tuesday, 1 September, brings a big 13.1 ft SW swell with a 14-second period – that’s huge, with NW offshore wind in the morning and SW cross-off in the afternoon. Energy is over 6200, so it’s expert territory. The water

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.
