The Lowdown
Right then, let’s have a look at what’s on the cards for the 4 Mile stretch.
Alright, I’ll be straight with you: the next 16 days are a bit of a grind for 4 Mile. There’s nothing that’s going to get your heart properly racing. The whole run is plagued by cross-onshore breezes, which are going to mess up the surface. It’s mostly a string of marginal to poor conditions, with a lot of small, short-period swell that’s just not going to offer much in the way of proper shape.
The first real chance of anything half-decent shows up on the morning of Sunday the 9th of August. The swell bumps up to 5 ft from the WNW with a period of 10 seconds, and the combined energy is moderate (644). But the wind is a cross-on at 6 mph, so it’ll be a bit on the lumpy side. It’s not a standout, just the best of a pretty average bunch.
The water temperature is sitting at 59°, which is about normal for the time of year, so no need to dig out the thickest rubber just yet.
The swell really drops off after that, with heights hovering around 2 ft to 3 ft from the SSW. The period does get long, up to 18-19 seconds on the 14th and 15th, but with such small swell and a cross-on breeze, it’s just not going to translate into anything rideable. The energy is there in the water (moderate, with readings like 412 and 568), but the wind is the enemy.
There’s no real stand-out session in this window. The best you can hope for is a bit of a cleaner window on the morning of Saturday the 22nd of August, where the wind is forecast to swing offshore from the SW at only 3 mph. The swell is tiny at 2 ft from the SSW with a period of 14 seconds, so it’s a long shot, but if you’re desperate and the tide is right, there might be a few glassy little runners. It’s more of a hope than a guarantee.
Honestly, this is a period where you’d be better off doing something else. The conditions are mostly poor, and the swell is small and messy. With the wind being so consistently cross-onshore, a lot of this setup is going to be far more interesting for kite surfers than for paddle surfers. We’ll wait for the next change.

Information about the 4 Mile Surf forecast
The above surf forecast table for 4 Mile provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 4 Mile can be found by selecting the local surf guide option on the grey menu. Our 4 Mile 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 (4 Mile) 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 4 Mile 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.
