The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up.
It’s a bit of a mixed bag, to be honest. There’s swell in the water, but the wind is going to be the main character for most of this run, and not in a good way. We’re looking at a lot of cross-onshore and choppy conditions. The water’s sitting at 60°, which is a touch warmer than normal for this time of year, so that’s a small mercy.
Starting with 4 Mile. This is a point break that likes a west swell, and we’re seeing a mix of that and some longer-period SSW groundswell. The problem is, from Saturday the 8th right through the next week, the wind is mostly cross-onshore. The best windows are going to be Tuesday morning the 11th and Wednesday morning the 12th, where we get a clean offshore wind from the SW. Those mornings will have a 4ft swell from the WNW with a 9-second period, and the energy is moderate (337-348). It won’t be firing, but it’ll be the cleanest you’ll find. The rest of that week is pretty much a washout.
The real standout, the one worth circling on the calendar, is the morning of Saturday the 15th. We’ve got a stronger SSW groundswell pushing in at 4ft with a 16-second period. That’s long-period energy, and on a point break, that can mean some really nice, drawn-out waves. The wind is light and cross-onshore from the SSW, but it’s light enough that it won’t ruin it. The combined energy is strong at 662, and it’s the best trade-off of size and quality in the whole forecast. It’s a week out, so it’s promising but not a guarantee.
The second week from the 17th looks similar to the start – a lot of cross-shore and onshore wind, and only a few marginal mornings. The morning of Friday the 21st has a light offshore wind from the SSW with a 3ft WNW swell, but the energy is weak (303). The afternoon of Saturday the 22nd sees a bump to 5ft from the WNW, but with a short 10-second period, it’ll be a bit lumpy. That’s the best of the second week, but it’s not the same as the 15th.
So, if you’ve got one session to aim for, make it the morning of the 15th. Otherwise, it’s a waiting game for the wind to cooperate.
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.
