The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I gotta be straight with you: the first half of this run is pretty grim. We’re looking at a long stretch of marginal to poor conditions, with a mix of cross-shore and cross-onshore winds that’ll keep the surface lumpy. The waves are small, mostly in the 2ft to 4ft range, and the combined swell energy is moderate for the first few days, hitting around 530 to 555 (moderate wave energy), but the wind just isn’t playing ball. The water temperature is sitting at 57°, which is bang on average for this time of year – nothing unusual there.
The first real glimmer of hope doesn’t show up until Tuesday the 28th of July. The morning session at 4 Mile looks like the pick of the early window. The wind swings light and cross-onshore from the west, so it’s not perfect, but it’s manageable. The swell is a clean 4ft from the SSW, with a solid 18-second period – that’s proper groundswell, meaning longer waits between sets but better shape. The combined energy is strong at 1286 (strong wave energy). This is a point break, so that long period will wrap in nicely. Keep in mind, this spot does see crowds often, so get there early if you can.
The standout of the whole forecast, though, is shaping up for Saturday the 2nd of August. Early morning, the wind goes light and onshore from the WSW at 4 Mile – that’s borderline offshore given the swell direction, and it’ll be glassy clean. The swell is 4ft from the S, with a 13-second period, and the combined energy is a solid 981 (strong wave energy). For a point break, that’s got some real punch. The water will still be about average for the time of year. This is the best window in the whole 16 days, no question.
After that, we get a bit of a bump in size on Monday the 3rd of August, with the swell hitting 6ft to 7ft, but it’s a short-period, windswell from the WNW (9 seconds) and the wind is cross-onshore, so it’ll be a choppy mess. That’s for the experts only if they’re desperate, but honestly, it’s not worth the paddle.
So, to sum it up: if you want a wave, aim for Tuesday the 28th of July morning, or lock in Saturday the 2nd of August morning – that’s the real gem. The rest of the time, you’re better off waxing your board and waiting.
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.
