The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at what’s on offer for 4 Mile over the next couple of weeks.
First off, I gotta be straight with you – there’s a real dry spell coming. The surf window kicks off on Tuesday the 11th of August, but it’s looking pretty marginal right from the start. We’ve got a small, weak W/NW swell pushing in around 3ft with a 9-second period, and the combined energy is only 344. That’s weak stuff. The morning has a light offshore breeze, which is a positive, but it’s barely enough to get excited about. By the afternoon, the wind swings cross-onshore, and conditions get messy.
Wednesday the 12th and Thursday the 13th are more of the same – small, short-period swells, mostly onshore or cross-onshore winds, and the scores are telling me it’s not worth paddling out. The water temp is about average for this time of year, so no surprises there.
Then we hit a shift. From Friday the 14th onward, a long-period S/SW groundswell starts to show up, but it’s tiny – only 2ft to 3ft. The period jumps up to 16-19 seconds, which is proper long-period energy, but the size just isn’t there to make it work. The wind, unfortunately, is mostly cross-shore or cross-onshore, and it gets stronger, especially on the 15th and 16th, with a moderate to fresh breeze. That’s just going to chop it up. The combined energy does climb into the 400s and 500s, but with those small wave heights and strong wind, it’s more of a kite-surfing setup than a paddle-friendly one.
The best of a bad bunch looks like Sunday the 16th of August in the morning. We’ve got a 3ft S/SW swell with a 16-second period, and the wind is a gentler cross-shore. The energy reading is 598, which is moderate, but it’s still a tricky combo. For a point break like 4 Mile, that long-period groundswell can sometimes wrap in nicely, but it’s inconsistent and the size is small. If you’re an advanced surfer and don’t mind a bit of a chop, that might be the only session worth a look.
After that, from the 18th to the 26th, it’s a long, bleak run. The swell drops back to 1ft to 3ft, the period is all over the place, and the wind is either cross-shore or cross-onshore, often moderate to fresh. The scores are consistently zero. There’s a short window on the 19th of August morning with a light offshore and a 3ft, 15-second swell, but it’s still marginal. The rest is just a write-off.
Overall, it’s a tough 16 days for 4 Mile. The only flicker of hope is that Sunday morning session on the 16th, but don’t expect much. The second week is particularly quiet, with a lot of days where you’re better off leaving the board at home.
Stay patient, and check back in case the forecasts shift.

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.
