The Lowdown
G'day, Rusty here. Look, I'm gonna level with ya. The next couple of weeks are looking pretty grim for 4 Mile. It's an advanced point break that faces west, but the swell energy coming through just isn't stacking up with the wind. We're in for a long dry spell, with no real good surf on offer for the first week.
Monday the 17th, we've got a weak 3ft swell from the SSW, but it's got some real grunt in the water with moderate wave energy (402). The problem is the wind is cross-shore, and it's just making things messy. That pretty much sets the tone for the rest of the week. Tuesday and Wednesday are more of the same, with small swell and cross-shore winds keeping things choppy. The wave energy is all over the shop, from 337 up to 520, but it's all for nothing with the conditions. By Thursday and into the weekend, we're looking at tiny 2ft to 3ft waves, and the period drops right off to 8-9 seconds, meaning no power at all. It's just a frustrating wait.
We have a bit of hope towards the end of next week. Friday the 29th of August and into the weekend, the swell from the SSW starts to pump a bit more, with the combined energy jumping up into the strong range (769 and 899). The wave height creeps up to around 4ft and the period is a nice long 16 seconds, which is proper groundswell. That's the kind of energy that can wrap beautifully around a point break like 4 Mile, but the wind is still a cross-onshore, which will put a bit of a bump on the face. It's frustrating, but that's the best we've got.
The standout window, if you can call it that, is Monday the 31st of August. The combined swell energy hits a strong 1242, with a 4ft SSW swell and that same long 16-second period. The wind is light and cross-onshore from the west, which is about as good as it gets for this stretch. It'll be a bit lumpy, but for an advanced crew, there'll be some long, grinding walls if you can dodge the wind bumps. Keep in mind, this spot sees crowds often, and with a long period swell like this, the sets will be few and far between but worth the paddle. The water temp is about average for the time of year.
After that, the first of September is a letdown again, with a smaller, shorter-period swell. It looks like the run of poor conditions is the new normal for a bit. If you're really itching, those last few days of August are your only real shot, but don't expect perfection.
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.
