The Lowdown

Alright folks, Rusty here with a look at what’s coming our way over the next couple of weeks.

Honestly, it’s a bit of a flat spell to kick things off. We’re looking at a lot of marginal and poor conditions for the first week or so. The swell energy is moderate, hitting around (433) on Sunday, but the wind is cross-onshore and the sets are on the weaker side. The water temp is sitting at 60°, about average for the time of year, nothing wild there.

For 4 Mile (a point break suited for advanced surfers), the real story is the lack of a solid clean window. Through Sunday the 9th and into Monday the 10th, it’s mostly cross-onshore breezes with small, short-period swell around 4ft to 4ft from the WNW, pushing the energy into the (400s). The guides say it’s marginal at best. We get a brief change mid-week with a lighter SW wind on Tuesday morning the 11th, offering clean-ish conditions, but the swell is tiny at just 3ft. Not exactly firing.

Toward the end of the week, the swell switches direction to the SSW and the period stretches right out – we’re talking 15 to 18 seconds, which is true long-period groundswell. This is where it gets interesting. The combined energy picks up significantly, hitting (686) on Saturday afternoon the 15th. The swell height will be around 4ft, but with that long period, 4 Mile could have some nice lines, especially if the wind stays light. The catch? The wind on the best days (Friday 14th afternoon and Saturday 15th afternoon) is mostly light and onshore or cross-onshore. There’s a window on Saturday morning the 15th with a light variable breeze and an offshore component from the SW, but the swell is a touch smaller. The water temp anomaly is about normal for the season.

For the second week, the outlook gets grim. From Sunday the 16th onward, we’re back to persistent cross and cross-onshore winds, often fresh breezes, and the swell drops back to the 3ft to 3ft range with energy in the (300s and 400s). It’s messy. There are enough poor condition reports to make you want to stay home. The only glimmer is on Friday the 21st morning, where we see a return to a 4ft WNW swell with a light cross-onshore wind, taking us back to the marginal territory we started with, but nothing to get excited about.

Truth is, this stretch of 16 days doesn’t have a clear standout. The best chance for a decent surf is probably the Saturday the 15th afternoon session, with that long-period SW groundswell and the energy pumping, but you’ll have to take the marginal tide and light onshore wind with it. If you’re a patient, advanced surfer, that’s your window. For everyone else, this is a waiting game.

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.
