The Lowdown
Alright, Rusty here, let's get into it.
We're looking at a pretty challenging stretch ahead. The surf’s gonna be a bit of a struggle for a while, and we’ve got a long gap with no real recommendations on the table. The first decent chance doesn't show up until Saturday, September 7th, but even then it's a marginal call. The pattern is mostly small, inconsistent swell with a constant cross-shore wind messing things up. For a point break like 4 Mile, which is a pretty advanced spot, all this wind is just making it a messy, lumpy affair. The water is sitting at 60°F, which is just about normal for this time of year – nothing wild there.
The only real standout in this whole 16-day period is a bit of a gamble. Let's talk about Thursday morning, September 18th. The swell is bumping up to 5ft from the NW, which is a solid step up from the tiny stuff we've been seeing. The wind is light and cross-onshore from the WNW at 6 mph, so it's not perfect, but it's the best on offer. The combined wave energy is moderate (680). This is for the crew who've been waiting, not for beginners though – 5ft is getting into the "know what you're doing" territory. It's a bit of a long shot this far out, so keep an eye on it.
Before that, from now until about the 7th, it's a surf drought. The only other remotely interesting window is Thursday morning, September 19th, with a tiny 2ft from the SSW. The wind is light offshore from the WSW at 3 mph, which would make it glassy clean, but the swell is just too small and weak to get excited about. The energy is feeble (295). A clean ankle-snapper.
So, in short: the second week of September is a write-off. The best bet is the potential for a bigger swell on the 18th, but it’s a long way out and the winds are still iffy. It’s been a tough run, but things can change fast.

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.
