The Lowdown
Alright, let’s have a look at what’s on offer over the next 16 days.
To be honest, it’s not looking like a classic run for us here. Most of the period is filled with small, wind-affected surf that just won’t get it together. The best of the bunch is a very short window that I’ll flag, but even that comes with a big caveat. The first real recommendation doesn’t kick in until the morning of Thursday, September 11th – so there’s a solid week of pretty ordinary conditions to sit through before we see anything worth paddling for.
Thursday, September 11th morning is the standout. 4 Mile is a point break, and it’s exposed to the west swell direction. We’re looking at a solid 8 ft swell coming from the SW, with a period of 12 seconds. That’s a decent groundswell, and the combined energy is pumping strong at 1874. The wind is a gentle cross-shore from the NW at 9 mph, which will keep things reasonably clean. This is the only real chance for a good session – it’s got size, energy, and manageable wind. However, this break is for advanced surfers only; 8 ft is serious, and the point setup will handle the long-period swell better than a beach, but it’s still a boatload of water moving. The water temp is 59°F, which is about average for this time of year, so no surprises there.
After that, on Friday, September 12th morning, the swell drops back to 3 ft from the SSW, with a gentle cross-shore wind. The energy is weak (469), and it’s just a bit of a letdown after the day before. The afternoon picks up a bit of wind, but it’s a cross-shore at 19 mph, making it lumpy and messy.
The rest of the outlook is a slow fade into smaller, weaker pulses. The mornings of September 15th and 16th see a tiny 2 ft SSW swell with light onshore winds, but the energy is minimal (196-212) and the wave comment suggests poor conditions. It’s not worth the drive for a knee-high wave with a side chop.
Friday, September 18th morning has a little more interest – a 2 ft SW swell with a very long period of 20 seconds, and light onshore wind. The energy is moderate at 632. That long period means the wave will have shape and power, but it’s a point break, so it might line up nicely. It’s a bit of a gamble that far out, but it’s the only other thing on the horizon that could be a quiet, clean session if the wind holds off.
So, if you’re an advanced surfer, circle Thursday, September 11th morning. For everyone else, it’s a waiting game. The runs of small, messy days are normal for this area, so don’t get too down – the forecasts can change, and we’ve seen it turn around before.

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.
