The Lowdown

Hey folks, Rusty here. Let’s get into it. Right now, our only real option on the table is 4 Mile, and honestly, it’s a tough stretch. The next 16 days start with a bit of a dry spell – there’s no surf worth paddling out for from Wednesday, July 15th, all the way through to the end of that week. The water is sitting at 60°F, which is a good 4°F warmer than usual for this time of year, so it’s notably toasty.

The first real flicker of something happens on Friday, July 24th. We’ve got a tiny 2ft swell rolling in from the SSW, but the period is a massive 24 seconds – that’s a very long period groundswell. The energy is heavy at 713 (Sunday morning) and 1516 (afternoon), but the catch is it’s coming from the SSW, which is cross-on for 4 Mile. The wind is light, only 6 mph, but it’s still cross-onshore, so expect some wind ripples. It’s still a marginal call, and the size is tiny. Not a standout.

The real standout, and the only true window of hope, is Saturday, July 25th. The morning session sees the swell bump up to 5ft from the S, with a period of 15 seconds – solid groundswell. The combined energy jumps to 1768, which is strong. The wind is light cross-onshore from the WNW at 6 mph, keeping it fairly clean. This is the best-looking day on the charts. The afternoon holds similar size at 5ft, period drops to 14 seconds, but the wind firms up to 12 mph and goes cross-shore, which will introduce a bit of chop. The morning is the pick.

After that, Sunday the 26th still has some size (5ft from the S, 13 seconds), but the wind is cross-onshore again, and it’s cloudy. The energy is still strong at 1431. It’s a marginal day, but if you missed Saturday, it’s worth a look.

The rest of the 16-day window, from Monday the 27th onward, drops back into a pattern of small, messy, cross-shore slop with swell around 3ft and periods in the 16-18 second range. The energy is moderate (around 684-807), but the wind stays cross or cross-onshore, and the scores are all poor. There’s no real recovery after that Saturday.

So, if you’re locked in, bank on Saturday, July 25th, early. It’s not perfect, but it’s the best we’ve got – clean enough, solid size, and that long-period S swell will have some push. 4 Mile is a point break, so it’ll handle that long period better than a beach break would, but keep in mind the light cross-onshore wind isn’t ideal. Crowds are likely here, so get in early.

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.
