The Lowdown

Alright, let’s get into it. Over the next 16 days, this stretch of coast is pretty quiet. The swell coming in is from the SSW and S, with periods bouncing between 13 and 18 seconds, so there’s a bit of deep ocean energy in the water, but it’s small and uneven. The wind mostly stays cross or cross-on, and the wave heights hover around 2 ft to 4 ft, so it’s not firing.

The first real chance of a surf is Saturday morning, August 29th, at 4 Mile. It’s a point break, exposed to the west, and the optimum swell direction is from the west, but the swell is coming from the SSW. Still, you get a 4 ft SSW swell with a very long period of 18 seconds, and the combined energy is moderate at 991. The water temperature is 59°, which is about normal for this time of year with a small anomaly of 0.5°. The wind is from the WNW at 12 mph, cross, so it’s not clean, but there’s some push. This is the only time in the first week where the swell tops 3 ft and the score is a 1. It’s not great, but it’s the best of a quiet run.

After that, Sunday August 30th through to Tuesday September 1st, the swell drops under 3 ft and the winds are mostly cross-on and choppy. The energy drops from 730 to 220, and the scores are all zeros. Wednesday September 2nd morning shows a 2 ft swell with a 16-second period from the SSW, but the energy is weak at 356. It’s still marginal.

From Thursday September 3rd to Saturday September 5th, the swell picks up a bit, with 4 ft on Thursday morning and 3 ft to 3 ft through Friday and Saturday. The period stays long, around 12 to 17 seconds, and the energy sits between 668 and 942, so moderate. But the wind is cross or cross-on, and the conditions are poor to marginal. Not a standout.

Sunday September 6th through Tuesday September 8th, the swell fades again, dropping to 2 ft, with energy down to 147. The wind is cross-on or glassy, but with such small waves, it’s a quiet stretch.

Then, on Wednesday September 9th, there’s a brief moment of hope. The morning shows glassy conditions with a 2 ft swell from the SSW at 16 seconds, and a score of 2. The energy is weak at 244, but clean surf is clean surf. The wind is from the WSW at 3 mph, glassy, so if you’re keen on a smaller board, this is the best it gets in the second week.

Thursday September 10th and Friday September 11th, the swell bumps up to 3 ft from the SSW, period 15 to 17 seconds, and energy around 471 to 639. The wind shifts to cross and cross-on, so it’s marginal again. Saturday September 12th and Sunday September 13th, the swell drops to 2 ft to 2 ft, with energy in the 200s and 300s. The wind stays light and cross-on.

Overall, the standout is Saturday morning August 29th, with the 4 ft, 18-second swell and moderate energy, despite the cross wind. The other close call is Wednesday September 9th morning, with glassy 2 ft surf. Both are small, but in a quiet forecast, they’re the moments to keep an eye on.

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.
