The Lowdown

Alright, Rusty here. Let's break down what's shakin' for the next couple weeks.

Well, I gotta be straight with you – the next two weeks are lookin' pretty bleak. There’s no real home-run session in the cards. We’ve got a long stretch of marginal to poor conditions, so if you're determined to get wet, you’ll need to pick your window. The water temp is sittin' at 60°F right now, which is about average for the time of year, nothin' to write home about.

The only session that has a glimmer of hope is Sunday morning, September 6th at 4 Mile. We’ve got a 3ft swell rollin' in from the SSW with a very long 15-second period – that’s proper groundswell. The combined energy is a moderate 674, so there's some power behind it. The wind is a light cross-shore from the WNW at 15 km/h (9 mph), which should keep the surface reasonably clean, maybe just a touch of bump. This is a point break, so that long-period swell should wrap in real nice. For an advanced spot like this, that’s about the best we’ll see. The afternoon goes downhill fast as the wind picks up, so the early session is the one.

From Monday the 7th through the end of the first week, it's cross-onshore wind and chop pretty much non-stop. Swell sizes are small, mostly between 2ft and 4ft, with periods droppin' back to a more average 13 to 14 seconds. The energy levels are moderate, but the wind just won't let up. Honestly, a lot of these afternoons look more suited for a kite than a paddle.

Into the second week, the swells get a bit bigger but lose a lot of their grunt. From Saturday the 12th onward, we see swell heights climb to 5ft and even 6ft, but the period drops right off to a short, weak 8 seconds – that’s windswell, no doubt. The wind stays cross or cross-on, and the energy readings are all over the place. Mornings might offer a cleaner moment with lighter breezes, like on Tuesday the 15th with a glassy offshore from the WSW at 5 km/h (3 mph) and 5ft swell, but that short period means it’ll be lumpy and hard to ride.

The tail end of the run, from the 19th on, sees the swell fade out again with small, long-period groundswell that just doesn’t have the size to make 4 Mile worth it for an advanced crew. It’s one of those stretches where you’re better off waitin' for the next system to roll through.

So, bottom line: Sunday morning, September 6th at 4 Mile is your best bet – decent conditions, a nice long-period groundswell from the SSW, and moderate energy. After that, it's a whole lot of nothin' special. Keep the wax warm and hope the models 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.

4 Mile is 12 km (7 miles) from Santa Cruz. If you plan a vacation in Santa Cruz, look for hotels and other accommodation in Santa Cruz. Santa Cruz has rooms for a wide range of budgets as well as car hire and transport links.
