The Lowdown

Alright, let’s talk surf. The outlook for this area is a bit of a grind, but there’s some hope if you’re patient. The main break we’re looking at is 4 Mile, a point break that’s wide open to the west and likes a westerly swell direction.

Right off the bat, the water temp is sitting at 59°F, which is about average for this time of year, just a shade warmer than normal.

We’ve got a long stretch of so-so conditions starting from Saturday morning the 18th. The swell is small, mostly 2ft to 3ft from the SW or SSW, with a period that’s long – between 14 and 17 seconds. That long period gives the waves some shape, but at this size, it’s not going to be pumping. The combined swell energy is moderate, ranging from about 415 to 765 over the first week, so there’s some push, but it’s not a lot.

The wind is the big issue. It’s almost always cross-onshore or cross-shore from the WNW or NW, which is putting a chop on the surface. The morning of Saturday the 18th has a light breeze but it’s still not glassy. The best bet in the first week is probably Tuesday the 21st afternoon, where you get a 4ft SSW swell with a 14-second period and a gentle cross-shore wind. It’s still marginal, but that’s the cleanest you’ll see in the first few days.

Moving into the second week, the swell picks up. From Monday the 27th of July, we start seeing 4ft to 4ft SSW swells with periods around 18 seconds. The combined energy jumps into the strong range, hitting 1064 on the 27th morning and even 1333 on the 28th afternoon. That’s a lot more power, but the wind is still a problem – moderate to fresh cross-shore winds from the WNW or NW, keeping the surface lumpy. This is a point break that would love a clean offshore, but it’s not getting it.

The long period makes these waves prone to breaking a bit straight at this exposed point, but the energy is there. For the advanced surfer, this is still worth a look, especially the morning of the 28th of July when the swell is 4ft with a 18-second period and the wind is a moderate cross-shore. It’s not perfect, but it’s the most consistent power we’ve got.

The end of the period into the first couple of days of August drops off. The swell direction swings more to the south, the period shortens to 11-13 seconds, and the energy drops to the 300-500 range. The winds are still onshore or cross-onshore, so it’s a tough run.

Overall, the best window is the last week of July, particularly the 27th and 28th, where the swell is bigger and the energy is strong. It’s not a classic, but it’s the most surfable we’ve got. Don’t expect perfection – this is a spot that needs a clean westerly to really shine. 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.
