The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for our stretch of coastline.

We’re lookin’ at a pretty flat spell ahead, I'm not gonna lie to ya. The waves are gonna be tiny and messy for a good stretch, so don't go gettin' your hopes up too soon. The only break we've got on the radar is 4 Mile, a solid point break for the advanced crew that's fairly consistent. The water temp is sittin' about average for this time of year, so no surprises there.

We kick off the forecast period with a long, quiet run. From Tuesday the 25th of August right through to Sunday the 6th of September, it's a real struggle. The swell is small—mostly under 3ft—and we've got a persistent cross-shore wind that's just choppin' up the surface. The wind's coming from the NW or WNW, which is cross to the swell, and it's messin' with any chance of a clean wave. The combined swell energy tries to build a bit on the 29th of August with a reading of 964, but that's still moderate energy and the wind just kills it. Most days the forecast is flagged as poor or marginal, so leave the board in the car.

There's a little glimmer that might interest the die-hards. On Friday the 4th of September, we start to see a bit of a pattern shift. The swell stays small—around 3ft from the SSW—but the wind lightens up, turnin' light cross-onshore. It's not perfect, but it's better than the lumpy chop we've been dealin' with. Then, Sunday the 6th of September looks like the best we've got for a paddle. On the morning of the 6th, the wind swings around to the SW at just 5 km/h (3 mph), which is light and onshore, but the lack of wind strength could mean a much cleaner surface. The swell is still small—0.9m (3ft) from the SSW—but the energy is moderate (439). For this stretch, that's a standout.

After that, the 7th of September has onshore wind again with a tiny 3ft swell, and the 8th and 9th are just back to small, choppy conditions.

If you absolutely need to get wet, that Sunday morning on the 6th of September at 4 Mile is your best bet for some clean, albeit small, lines. But honestly, with the persistent cross-shore winds and small waves that dominate most of the outlook, this setup would actually be more interesting for a kite surfer than a paddle surfer on those windier days. For the rest of us, it's a tough stretch.

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.
