The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for Fourth Beach over the next couple of weeks.
Right off the bat, we’ve got a pretty solid run of swell coming in, but the wind is going to be the main character for a lot of this period. The water temp is sitting at 62°F, which is about average for this time of year, so nothing wild there.
The week starts slow. Wednesday afternoon has a chunky 8ft SSW swell, but that 30 km/h easterly is going to ruin it, making for a lumpy cross-chop. Not worth paddling out for. Thursday morning cleans up a bit with a cross-offshore breeze, dropping the swell to a cleaner 6ft, but it's still just a marginal session. The real glimmer in the first week is Friday morning, September 11th. The swell drops to a manageable 5ft from the SSW, but that 15 km/h NE cross-offshore wind is a dream. The period is a solid 16 seconds, giving it some real push. The combined energy is moderate (1305), and the forecast is calling for very good surf conditions. This is the pick of the first week, without a doubt. It’s a reasonably consistent spot, so you won't be completely alone, but it should be well worth the paddle.
The weekend gets messy. Saturday morning looks clean with a strong WNW wind, but that cross-offshore stuff is a bit tricky. Sunday is a write-off with onshore winds. Then Monday and Tuesday of the second week (14th and 15th) see a big pulse of energy, with swell heights pushing 8ft to 10ft and combined energy readings in the 2000-3000 range (strong), but it's all cross-onshore and choppy. That’s more of a kite-surfing setup than a paddle-surfing one, if you ask me.
The real standout of the entire forecast, however, is a bit further out. Sunday afternoon, September 20th, is the one to circle on your calendar. The swell is a modest 4ft from the SW with a 13-second period, but the wind is glassy. Dead flat. The forecast says "expect very good surf conditions," and I’m not arguing. The combined energy is moderate (831), but when it's glassy, quality trumps size. The water will be like a mirror. This is the hidden gem of the outlook.
The final week sees another big swell pulse around the 21st and 22nd, with monster energy values (3678 and 4994), but the wind is a mess again. That 10ft swell on the 22nd afternoon with onshore wind is a beast for experts only, and even then, it’ll be a battle. The 23rd and 24th look like a total washout with strong winds and rain.
So, to wrap it up: the best surf is Friday morning, September 11th for a solid, clean, long-period swell, and the absolute gem is the glassy session on Sunday afternoon, September 20th. Get on it.
Rusty.

Information about the Fourth Beach Surf forecast
The above surf forecast table for Fourth Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Fourth Beach can be found by selecting the local surf guide option on the grey menu. Our Fourth Beach 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 (Fourth Beach) 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 Fourth Beach 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.
