The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at 4 Mile. Straight up, this is a tough outlook. We’ve got a long, long stretch of mediocrity ahead, so don’t get your hopes up for anything spectacular for a while.
First thing you need to know about 4 Mile – it’s an advanced point break that’s fairly consistent, but it’s exposed to the swell and the optimum direction is from the W. We’ve got a south-southwest groundswell pattern setting up, and that’s not exactly what this spot is begging for. The water temp is sitting at 60°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing your arse off for the tiny, disappointing waves we’re about to look at.
Starting off on Tuesday, 18th August, the afternoon sees a little pulse of 3ft SSW groundswell with a long 16-second period. The combined energy is moderate (511). But here’s the kicker – the wind is a cross 16 mph from the WNW. It’s going to be lumpy and messy. The call is marginal at best. Not worth paddling out for, in my book.
From Wednesday the 19th all the way through to Saturday the 29th of August, it’s a bleak run. We’re looking at days on end of poor surf conditions. Swell heights mostly sit between 1ft and 4ft, with periods all over the place, and that wind just won’t let up – it’s cross or cross-on from the WNW or NW. The wave energy stays weak to moderate all the way through. The surf report itself keeps calling it “poor” or “marginal.” Honestly, there’s about a 10-day hole here where I wouldn’t even bother waxing the board.
The only flicker of a highlight comes around Thursday afternoon, 27th August and into Friday, 28th August. On the 27th, the afternoon swell bumps up to 5ft from the WNW, but with only an 8-second period – that’s short period, windswell junk. The energy hits 629 (moderate). Still, the wind is a cross 9 mph, so it’s going to be chopped up. On Friday the 28th, the afternoon sees 5ft NW windswell with a 9-second period and the energy jumps to 830 (strong). The wind is cross 16 mph though, so it’ll be a bumpy, cross-shore mess. For an advanced spot like 4 Mile, that’s only going to be for the hardcore guys who don’t mind a wrestle and want to get out of the house. It’s not clean, it’s not pretty.
Bottom line: if you’re a kite surfer, this whole window might look fun with that cross-shore wind and some size, but for a paddle surfer, this is a write-off for nearly two full weeks. The only day that even hints at being surfable is Friday the 28th afternoon, and even then, you’re dealing with lumpy windswell. Don’t hold your breath.
Rusty.

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.
