The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for our local stretch.
It's a bit of a slow start. We've got a few days of marginal stuff coming through, but nothing you'd rush out for. The water is sitting at 61° right now, which is a couple of degrees warmer than usual for this time of year – noticeably warm, so you might not need the thickest suit.
The first real standout, and the only one I'd call a winner, pops up on Tuesday, 21 July. The morning is looking like a dream with glassy conditions and a 4ft swell from the SSW. The wind is dead calm, coming from the SE at 3 mph, so it'll be clean as a whistle. The period is a solid 14 seconds, which is proper groundswell energy, and the combined energy is sitting at 752 (moderate). The afternoon keeps that glassy feel with a slight bump up to 5ft from the same SSW direction, with a period of 12 seconds and energy of 823. This is your window. Expect some good, clean waves at 4 Mile – just be aware that crowds are often around here, so get there early.
The rest of the fortnight is a mixed bag of cross-shore winds and lumpy conditions. The swell sticks around, but the wind just doesn't play ball. By the end of the month, around Thursday, 30 July and Friday, 31 July, the wind swings light onshore from the south, offering a bit of hope with small, clean-ish surf in the 3ft to 3ft range, but it's nothing to write home about. The energy drops right off into the 500s range by then, too.
Overall, it's a one-day wonder. Tuesday is the call. After that, you're better off waiting for the next forecast update.
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.
