The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for 4 Mile.

First off, I gotta be straight with you—this is a grim stretch. For the next week and a half, we're looking at a whole lot of almost-nothing. The swell is tiny, cross-shore winds are a constant buzzkill, and the energy just isn't there. You'll be staring at a lot of lumpy, bumpy, barely-rideable slop. The real tease is a couple of days in early September that show a bit more life, but even then, it's a case of "low expectations."

Right now, through the end of August, forget it. The swell is barely a ripple, barely over 2 ft, and the wind is almost always cross or cross-on. The combined energy is weak, barely cracking 300 on the best of the bad days, and mostly sitting in the low to mid 200s. It's a lot of paddling for nothing. The one slight flicker is on Friday, August 29th morning, where the energy jumps up a notch (1035), but it's still crossed-up and messy, with a 4 ft swell from the SSW. It's not worth the drive.

The real standout, if you can call it that, is the window around Friday, September 4th. The morning session looks like the best chance we're going to get. Swell from the SSW bumps up to 3 ft with a very long period of 18 seconds, and the combined energy is strong, hitting 1262. Best of all, the wind is forecast to be light and offshore from the WSW. That's clean. That's the kind of glassy morning that can turn a small swell into something fun on the point. The downside is that with such a long period, it might be a bit too straight at the beach, but on a point break like 4 Mile, it could line up nicely. The 3 ft size is small, so it's not a big day, but it's clean.

The afternoon of Saturday, September 5th is another mention. Still a small 4 ft SSW swell, but the wind swings light cross-on from the SSW, and the energy is strong (1006). It won't be as clean as the Friday morning glass-off, but it's a solid second option.

The rest of the first week of September is just a rinse-and-repeat of marginal conditions. The swell sticks around 2 ft to 4 ft, but the wind is always cross or cross-on, keeping the surface chopped. It's not going to be the kind of quality that gets you out of bed.

So, bottom line: This is a long, lean stretch. The only real moment to circle on the calendar is the morning of Friday, September 4th for a chance at some clean, peelable waves on the point. It's not a classic, but it's the best of a weak bunch.

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.
