The Lowdown

Alright, Rusty here, and we’re sizing up 4 Mile, a point break that’s for the experienced crew only. The forecast is a bit of a slow burn.

Water temp is sitting at about 57°F, right on the seasonal average. The wave energy is moderate through most of the run, with combined swell energy numbers bouncing between 350 and 1400 (moderate to strong), but there’s a lot of cross-shore wind in the mix that’ll mess with the face.

It starts Sunday the 19th with a 3ft swell from the SW, with a 17-second period – that’s proper long-period groundswell, great for a point. But the wind comes from the WNW at 9 mph, cross-onshore, and the call is "poor surf conditions." Choppy and not worth it. Monday to Wednesday is more of the same: 2ft to 4ft swells, but with light to moderate cross-shore breezes and poor to marginal surf. Thursday the 24th brings a tiny 2ft SSW swell with a crazy 24-second period, but it’s still cross-shore wind. The energy is moderate at 996, but the surface will be bumpy.

Now, Saturday the 25th and the following days see energy jump up to the 1300–1400 range (strong), with 3ft SSW swells and periods around 18-21 seconds. But again, the wind stays a moderate cross-shore at 12 to 15 mph. It’s a "marginal" call. The long period and cross wind don’t mix for clean waves here.

Your best shot is Sunday morning the 2nd of August. We’ve got a 4ft S swell, 12-second period, and for once the wind is light offshore from the WSW at 6 mph. That’s glassy, clean conditions. The energy is moderate at 612, but the wind quality will make it the standout session of the whole 16 days. The rest of that week tails back into small, choppy surf.

Expect long empty stretches here. The first ten days are mostly poor. Crowds are likely when the surf’s on, and that Sunday morning window will probably have a few heads out. Worth the wait if it holds.

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.
