Alright folks, Rusty here. Let’s get into it.
Honestly, looking at the next two weeks, it’s a grim start. We’ve got a solid 14 days of pretty ordinary conditions at Middles/Generals. The wind is stuck onshore from the ENE, blowing a fresh to strong breeze (19-25 mph), and that’s just gonna keep the ocean messy with a lumpy cross-chop. The swell sits around 5ft to 7ft, but it’s short-period stuff at 7-8 seconds, so it’ll be weak and wonky. The combined wave energy is moderate (values between 314 and 809), but with that wind, it’s just not worth paddling out. The water temp is 80°, which is about average for this time of year, so at least you won’t freeze while you’re getting frustrated.
Then, around Tuesday, July 21st, the game changes. A long-period groundswell rolls in from the east, pushing 4ft to 4ft at 16 seconds. The energy jumps up to 1284, which is strong. This is a very long-period swell, so it’ll be breaking straight at this beach setup, but it could still offer some decent lines. The wind is still a moderate cross-shore, so it won’t be glassy. The standout here is Wednesday, July 22nd afternoon. The swell drops to 3ft at 14 seconds, but we get a glassy, clean surface with light SSE wind at 3 mph. The conditions are described as "very good," and that’s the best we’ll see. The energy is still strong (731), so it’s a proper session for the patient crew.
Crowds? This spot is "often" busy, so expect company on that Wednesday glass-off. The swell direction is east, close to the optimum (ESE), so it’ll be hitting the break right. Forget the early part of the window; the only real time to get wet is that Wednesday afternoon. For the rest of the run, you’re better off taking a break.
Rusty.

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 Middles/Generals 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.
