The Lowdown
G’day, Rusty here. Look, I’ll be straight with you—this 16-day window for 4 Mile is a bit of a mixed bag, and it’s gonna take some patience. The first real standouts are a few days away, but we’ve got a couple of windows that’ll be worth paddling out for if you can read the lineup.
The whole period kicks off with a bit of a wait. From Friday the 4th right through to Tuesday the 8th, it’s all pretty marginal. We’ve got a moderate swell rolling in, around 3ft to 4ft from the SSW, with periods between 14 and 18 seconds—that’s solid groundswell energy, plenty of push. The combined energy sits in the moderate range (830 to 564), so there’s some grunt there. But the wind is a problem. Most of those days are cross or cross-on, with a few afternoon breezes up to 19 mph, which just chops things up. The water temp is 59°F, about average for the time of year, nothing unusual.
Now, Wednesday morning the 9th—that’s where it starts to get interesting. We’ve got glassy conditions, dead calm wind, and a 4ft S swell with an 11-second period. The combined energy is 461, moderate, but with that glassy surface, it’ll be clean as a whistle. 4 Mile is a point break, so it handles that kind of swell well. It’s a fairly consistent spot, but crowds are often here, so you’ll likely have company. Still, that morning session is the pick of the first week.
The real standout, though, is Thursday morning the 10th. Zero wind, glassy, and a 3ft SSW swell with a 17-second period. That’s a long-period groundswell, and combined energy shoots up to 697—moderate but punchy. For a point break like 4 Mile, that long period will wrap in beautifully, offering long, clean lines. That’s the best on offer, no question. The afternoon glass-off is solid too, with a light offshore breeze, but the morning is the gold.
After that, we hit a long dry spell. From Friday the 11th all the way through to Thursday the 17th, it’s mostly poor conditions with small swell (1ft to 3ft) and cross-winds. There’s a tiny window Saturday afternoon the 12th with glassy conditions and a 2ft SW swell, but it’s small and inconsistent. Not worth rushing for.
Then, on Friday the 18th, we get a spike. A 6ft WNW swell with a short 9-second period, combined energy 795—moderate, but that short period will be a bit lumpy. This is expert-only territory, over 5ft, and with cross-shore winds up to 19 mph, it’s going to be a mess. Saturday the 19th is similar, 6ft from the WNW, still short period, but with lighter winds in the morning. Honestly, for a beach or point setup, this is more of a kite-surfing window than a clean paddle session.
So, to wrap it up: Thursday morning the 10th is your standout—glassy, long-period SSW groundswell, clean lines at 4 Mile. Wednesday morning the 9th is a solid backup. The rest of the two weeks, you’re either waiting on wind or dealing with small, choppy junk. Keep an eye on the forecasts, but for now, mark that Thursday in your calendar.
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.
