The Lowdown

Righto, Rusty here, and let me tell you what’s cookin’ at 4 Mile over the next couple of weeks.

This is a proper point break, exposed to the west swell, but getting the right direction is key. It’s a spot for the advanced crew, and it’s fairly consistent, but you’ll be sharing the water often, so keep your head on a swivel. The water temp is 58°F, which is actually about 1°F cooler than normal for this time of year – nothing too wild, just a bit of a nip in the air.

To be honest, the first week and a bit is a grind. We’ve got a decent amount of energy floating around, with combined swell energy readings bouncing between 175 and 934, so there’s some push there, but the winds are just not playing ball. It’s mostly cross or cross-onshore all day, which is turning what could be a fun, long point ride into a choppy mess. The waves are hanging around the 1 ft to 4 ft range, but the quality is poor. Even when the period gets up to a solid 19 seconds on the 3rd of September, turning that long groundswell into a tidy wave, the wind spoils it.

There are a few mornings that look *nearly* there, like the 5th of September with a light offshore wind, 3 ft swell and a 16-second period, but it’s still tagged as marginal. The 9th of September Wednesday morning is a bit of a tease – glassy conditions, 1 ft of swell, but it’s a long 19-second period, which can be tricky on a point like this, and the size is barely enough to get a proper ride.

Now, for the standout. The best bet in the whole window is Thursday the 10th of September morning. The swell is going to jump to 6 ft from the WNW, with a 12-second period, and the combined energy is a strong 1200 – you’ll feel that push. The wind is light cross-onshore, but at that size and period, it should still offer some solid, fun waves. It’s a bit big for beginners, but for the advanced guys, that’s the session to point your board at.

After that, it drops off again. Friday the 11th still has some size at 5 ft, but the period shortens and the wind turns onshore. The rest of the week is a slow fade back into smaller, wind-affected waves, finishing off in the 2 ft to 4 ft range with light, but wrong-direction winds. The second week is a write-off, with nothing worthwhile to get excited about.

To sum it up: the first two weeks are mostly about dodging the wind. If you can only pick one session, make it the Thursday the 10th of September, but don’t get your hopes up for much else.

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.
