The Lowdown
Alright folks, Rusty here, looking at the 16-day run for Fourth Beach. We've got a chunky period ahead, but it’s not for the faint-hearted. This spot is an advanced-only setup, and it's consistent, so when it's on, it’s on, but when it's too big, it’s a whole different beast.
We're kicking off with a massive pulse of energy. On Tuesday afternoon the 11th, it's already pumping big with a 15 ft SSW groundswell, packing 15550 (moderate to strong energy) but with a 22 mph cross-on wind, it's going to be a lumpy, blown-out mess. Not the day to paddle out. Wednesday the 12th stays big at 13 ft with that long-period SSW swell, and the wind improves to a moderate cross-shore, but honestly, it’s still too big to be fun. The real standout of the first week actually arrives on Thursday morning the 13th. The swell drops just a touch to 12 ft, but we get a light WNW cross-off breeze at 6 mph, making for clean conditions. That's the window for the experienced crew. It’s still solid, expert-level stuff at 12 ft from the SSW, but the clean face makes it worthwhile.
The energy backs down a notch into the weekend, with 10 ft to 7 ft on Friday and Saturday. Friday afternoon the 14th looks best of that bunch: the swell is still a respectable 10 ft from the SSW, and with a light easterly cross-off at 6 mph, it cleans up nicely. The combined energy is still in the moderate range at 4396. That's the best on offer for the first week for strong intermediate or advanced surfers, but it's still a heavy wave.
After a bit of a lull early next week where the swell drops under 7 ft and the wind isn't great, the run gets interesting again late in the second week. Keep an eye on Wednesday the 19th afternoon. The swell bumps back up to 7 ft from the SW, and the wind goes totally glassy with a 3 mph SE breeze. The wave energy is 2602 (moderate), and conditions will be perfect. This is the other prime window for advanced surfers looking for clean, lined-up sets on that long-period SSW groundswell.
Later, on Sunday the 23rd afternoon, we get another glassy moment with 8 ft of SSW swell and a 3 mph WSW breeze. That'll be clean and solid again. The crowds at Fourth Beach are sometimes a thing, so you might have company, but with these sizes, the crowd will be thin.
One last note: that Tuesday the 25th brings another huge spike in energy (13822) with 13 ft swell and a gentle cross-on. It's too big again, so only the true watermen will be looking at that.
Remember, the water temp is 61°F with no anomaly, so it's about average for the time of year.
Stay safe out there.

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.
