Alright folks, Rusty here. Let’s have a look at what’s lining up for the next couple of weeks. It’s not a classic stretch, but there’s a few moments where it could get interesting if you’re patient.

The overall pattern is a bit of a slow burner. We’ve got small, messy conditions for the first week, with a lot of cross-onshore wind and choppy surfaces. The wave energy is moderate early on, with combined energy readings in the 400s (445), but the quality is poor. The water temperature is sitting at 59°F, which is a touch warmer than normal for this time of year – not a big deal, but nice if you’re in a spring suit.

Sunday the 12th is a write-off. Small 3ft swell from the SSW, period around 14 seconds, but it’s crossed up by a W wind. The energy is moderate (447) but the surface is choppy. Monday the 13th is similar – tiny, messy, not worth paddling out.

Tuesday the 14th sees a shift to a short-period WNW swell, only 8 seconds, but it’s still small and the wind stays cross or cross-on. Not great. Wednesday the 15th has a little more size – 5ft from the NW – but again, short period (8 seconds) and cross winds. The energy is moderate (528) but the quality is marginal at best.

Now, Thursday the 16th is the first real standout. The swell picks up to 8ft from the NW, period 9 seconds, and the combined energy jumps to 1497 – that’s strong wave energy. This is a big, powerful swell for 4 Mile. However, it’s a point break, and with a 9-second period, it’s not a classic groundswell. The wind is a moderate cross-shore, so it’ll be lumpy. This is advanced territory – 8ft is big, so leave the beginners on the beach. It’s the best on offer in the first week, but it’s far from perfect.

After that, Friday the 17th drops back to 5ft, and the wind stays cross-on. The rest of the week from the 18th to the 24th is a long, flat, and poor stretch. Swells drop to 2ft to 3ft, mostly from the SSW or S, with very long periods (16-20 seconds). Those long-period swells are prone to wrapping straight at a point break, but the energy is only moderate (around 450-600) and the wind is almost always cross-on. The 24th is particularly weak – energy down to 189.

The second week brings a little hope. Saturday the 25th has a 5ft S swell, period 14 seconds, and the energy jumps back into strong territory at 1052. But the wind is a fresh cross-shore, so it’ll be lumpy again. Sunday the 26th and Monday the 27th are small and messy again, with very long-period SSW swells (18-20 seconds) but poor wind.

So, the one true standout in this entire 16-day window is Thursday the 16th of July. That 8ft NW swell, with strong energy (1497), is the biggest push we get. It’s a point break, so that long-period energy (9 seconds) will wrap in nicely, but the cross-shore wind will keep it from being glassy. It’s a day for the advanced crew only. For the rest of it, you’re mostly waiting.

The crowds at 4 Mile are listed as “often” – so expect company on that Thursday peak.

Rusty out.

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.
