The Lowdown

Alright folks, Rusty here. Let's have a look at the outlook for 4 Mile.

To be honest, this stretch of the coast is in a bit of a flat spell to kick things off. The water temp is sitting at a noticeably warm 61°F, which is a touch warmer than normal for this time of year, but that's about the only thing pumping. We're looking at a long stretch of small, weak surf with nothing really worth paddling out for until we get into the back half of the window. The first week is a write-off, with the odd marginal session but nothing you'd get excited about.

Now, around Monday the 21st, we start to see a pulse of energy. The combined swell energy jumps up to 916 (moderate wave energy) early that morning, with a short-period 6ft NW swell. The winds are light and cross-on, so it's not going to be glassy, but it'll be a step up from the dribble we've been seeing. Still, it's only a marginal call at best. The pattern stays marginal and small through that whole week, with a mix of small SW and SSW groundswells that have decent period but just lack any real size.

If you’re looking for the standout, you're going to have to be patient. The best bet in this whole 16-day window looks like it could be 4 Mile on the morning of Monday the 21st. It's a point break, which is good because those long-period SW swells tend to break a bit too straight on a beach, but a point like this can really line them up. The swell is a short-period 6ft from the NW, and the wind is light from the WSW at 3 mph, so it’s cross-on but light enough that it won't ruin it. The combined energy is a solid 916 (moderate wave energy), but with 6ft of swell, this is advanced territory. It's also a spot that is "often" crowded, so expect company, but that's the price you pay when the conditions line up. The rest of the window is just more of the same small, weak, onshore slop.

Keep your eyes on the horizon, the forecasts can always change.

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.
