The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for 4 Mile over the next couple of weeks. It’s a point break that needs a good W or SW swell to light up, mostly for the advanced crew. The water temp is sitting about average for this time of year, nothing wild to report.
We’re looking at a pretty quiet start, honestly. The first few days from Thursday the 13th through to the 21st are mostly a write-off. There’s nothing happening that’s worth getting excited about. We’ve got a small, long-period SSW groundswell bumping through, but it’s all cross-onshore wind messing up any chance of clean waves. The combined energy is stuck in the low to mid hundreds (334–631), which tells you there’s not much push. The wind state is “gentle cross-onshore” or “moderate cross-shore” all the way through—always choppy or with a cross-chop. You’d be paddling your brains out for nothing.
Now, the first moment things start to look interesting is around Tuesday the 18th. We get a shift in swell direction to NW, and the period drops to a short 8 seconds. That’s a windswell, not a groundswell, so it’s lumpy and not the best shape. The height bumps up a bit to 6 ft in the morning, but the wind is still cross-shore. The combined energy climbs into a stronger range (849), but the quality is still marginal. Not your best bet.
The stand-out moment, and I mean the only real stand-out in the whole forecast, is Wednesday morning the 19th. The swell holds from the NW at 7 ft with that short 8-second period. That’s getting solid—big enough that beginners should stay out, and even intermediates might find it a handful. This is expert territory. The combined energy jumps way up to 1245, which is strong. The wind is a light cross-shore, so there won’t be much chop, but it’s not glassy offshore. For a point break like this, the short period and slight cross-chop means the waves won’t be super clean, but there’ll be plenty of push. It’s the best on offer, but don’t expect perfection.
After that, from the 20th onward, it fades back into the same old story: small swell, poor surf quality, and cross or cross-onshore winds. There’s a little bump of NW swell around Thursday the 27th with 5 ft and short period, but the wind messes it up again. The rest of the days are just flat or junk.
So, if you’re a confident surfer and want the biggest energy window, get out for the morning of Wednesday the 19th. Everything else in this 16-day stretch is a hard pass.
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.
