The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on offer.

Honestly, the next few weeks at 4 Mile are a real mixed bag. We’ve got a long period SSW groundswell hanging around, but the wind is just not our friend. For the most part, it’s cross-shore or cross-onshore, which is going to keep the surface lumpy and choppy. The real standouts are few and far between, so we’ll be scratching for clean ones.

The first real chance to get a wave comes Wednesday morning, July 22nd. We’ve got a 3ft swell from the SSW with a very long period of 15 seconds, which means real groundswell energy. The combined energy is moderate (606), and with the wind swinging light and onshore from the SW at only 3 mph, it’s actually glassy. That’s the one window for a decent session, but it’s marginal. That very long period will make for some beautiful, drawn-out lines on this point, but it’s an advanced wave, so you’ll need to know what you’re doing. The water temp is about average for this time of year.

After that, from Wednesday afternoon through to the end of July, it’s a write-off. The wind is up from the NW, 12 to 19 mph, and it’s cross-shore all day, every day. The wave heights bobble around 2ft to 3.5ft, but the wind is just ruining it. The combined energy climbs up a bit, but it’s all for nothing. Thursday morning, July 30th, shows a brief spike to 6ft from the NW, but the period is a short, weak 8 seconds, and the wind is still messy. That’s a messy, weak windswell.

The first few days of August don’t look much better. The wind from the WNW keeps the conditions cross or cross-onshore, with swell heights hovering around 2.5ft to 4ft. The energy is moderate at best. There’s a small window on Saturday morning, August 1st, with a gentle breeze and a 3ft S swell at 16 seconds, but it’s marginal. The best bet in this whole stretch is that Wednesday morning, July 22nd. It’s not huge, but it’s the only time the wind is light and the swell is long and clean.

Short Range Forecast

Mostly dry. Warm (max 22°C on Fri afternoon, min 14°C on Wed night). Winds increasing (light winds from the S on Tue night, fresh winds from the NW by Thu afternoon).

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.
