The Lowdown

G’day, it’s Rusty. Let’s break down what’s firing at Middleton Beach for the next couple of weeks.

We start on Tuesday the 18th with clean 8ft to 8ft of south-west swell rolling through, water temp at 64°, which is a touch warmer than normal for this time of year. The energy is solid, around 3200 to 3276. Morning cross-off breeze, going fully offshore in the arvo. A good start.

Wednesday the 19th brings a step up, with 10ft to 12ft of swell and energy jumping to over 4600 and then 6258. Still cross-off, but the forecast flags it as marginal, likely tide-affected. It’s getting into that more powerful territory.

Now for the standout. Thursday the 20th is the one to circle. We’ve got 12ft of clean south-west groundswell, periods at a solid 16 seconds, and the energy is cranking – over 6000 in the afternoon. With a moderate offshore in the morning and a gentle cross-off later, this is “excellent surf for experienced surfers.” That’s the pick. This size is well over 8ft, so it’s not for the faint-hearted.

Friday the 21st still has 10ft of swell, with a lovely light north-west cross-off in the morning and 15-second periods. Energy is still strong at 4549. The morning is the go, as the wind swings onshore from the south-east in the afternoon.

Saturday the 22nd is another good one. Morning has 10ft of south-south-west swell, 16-second periods, and a slight offshore breeze with energy at 3971. It’s “very good” and clean. The afternoon drops off a bit.

Sunday the 23rd eases back to around 7ft, but the wind picks up to a moderate 25 km/h cross-off. Energy is moderate at 2248 to 2734, but the forecast is only marginal. Surfable, but not a patch on Thursday.

Monday the 24th is a drop in size, with 5ft to 5ft of swell and energy down to around 1145-1293. It’s clean with light winds, but not much push. A “good” surf, not great.

Then, hold on. Tuesday the 25th brings a serious pulse. We’re looking at 13ft to 15ft of swell, but the wind is howling offshore at 40-45 km/h. Energy is strong at 3496 to 4628, but with that much swell and wind, it’s a battle – “strong offshore and clean but hard to paddle into.” That’s for the elite only.

Wednesday the 26th keeps the size at 13ft, with energy maxing out at 7408 in the morning – very strong. Wind is a fresh 30 km/h cross-off, and while clean, it’s a heavy, powerful ocean. The forecast calls it marginal, which at that size means it’s intense.

Then we hit a lull. Thursday the 27th and Friday the 28th see the swell drop to 3ft to 6ft, but the wind goes all over, with strong cross-shore and cross-onshore. Energy drops below 1600, and conditions are “poor.” Leave the board in the car. Saturday the 29th brings back some size – 8ft – but with a moderate cross-shore chop in the morning. The afternoon cleans up with a cross-off and energy around 3300, so that arvo session is on.

Sunday the 30th is cleaner with 7ft of swell and gentle cross-off winds. Energy is moderate at 1718-1601, and it’s a “good” surf, not epic.

The first week of September, Monday the 31st and Tuesday the 1st, sees a consistent push of 7ft to 8ft south-west swell, with 16-second and then 14-second periods. Energy is around 2344 to 2869. Tuesday especially has a moderate offshore in the morning and looks clean with “very good” conditions. Wednesday the 2nd of September fades to 6ft, still clean, but that’s about it.

So, overall: Thursday the 20th is the clear standout – big, powerful, and clean. The early window on Friday the 21st is also worth it. The late-month swells in the second week are promising but less certain. And watch out for that massive, windy day on the 25th – that’s a kite day for sure, not for paddling.

Signing off, Rusty.

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.
