Alright, let me tell you what I’m seeing for this stretch.

Honestly, mate, the next week or so is a tough one. We’ve got a long dry spell at 4 Mile with the wind and swell just not lining up for good clean waves. It’s a bit of a frustrating run, to be honest. The first real glimmer of anything decent doesn’t pop up until Sunday morning the 19th of July, and that’s the one you want to circle.

Let me walk you through it. Starting now and through the bulk of the second week, most sessions are either cross-shore or cross-onshore, with moderate to fresh breezes that are chopping up the surface. The swell is hanging around small—mostly under 3 ft through the first days, with a very long period SSW groundswell (16-19 seconds) rolling in, but it’s just not clean enough to get excited about. That long period stuff can be tricky on a beach break too, wanting to break a bit too straight. Wave energy is moderate overall – getting up into the 400 to 1153 range – but the wind is the killer.

On Thursday morning the 9th, we get a spike in size to 7 ft, but it’s a short-period NW windswell (only 9 seconds) with moderate cross-onshore wind. That’s messy, lumpy, and not going to be any fun to paddle out into. For beginners, that size with that wind is just a washing machine. That setup looks more interesting for kite surfing than paddle surfing.

Then Friday the 10th and Saturday the 11th settle a little, with the swell dropping back to around 4 ft to 5 ft, still a short-period WNW windswell, and we finally get a light wind though still cross-onshore. It’s *possible* you’ll find a cheaky one, but the wave quality is still marginal at best.

Now, here’s the standout. Sunday morning the 19th of July. This is the one. The wind goes glassy out of the SSW at just 5 km/h, and the wave comment says “expect very good surf conditions.” The swell is a solid 5 ft coming from the WNW with an 8-second period, and the combined energy is moderate at 582. That glassy wind is a major positive – that’s the clean, smiling wave you’ve been waiting for. It’s still a short period, so it’ll be a bit more playful and less powerful than a groundswell, but on the glass, that’s a beauty. Keep your eyes peeled for that window.

After that, Monday morning the 20th still shows 6 ft from the WNW with a 10-second period and light wind, but it’s back to cross-onshore, so it won’t be as clean as the Sunday glass-off. It might still be worth a look, but the Sunday morning is the real keeper.

For water temp, there’s no anomaly data given here, so I’ll say it’s just doing its usual thing for the time of year.

Hang in there. The wait is long, but that Sunday glass-off looks like it’ll make it all worth it. Crowds are often at 4 Mile, so bring your patience on top of your board.

Stay stoked.

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.
