The Lowdown
Alright, listen up, it's Rusty. I've been grinding through the numbers for our local zone, and I won't lie to you – it's a tough row to hoe. The next sixteen days are looking like a real fight against the wind, and the swell is all over the place. We're looking at a long, frustrating gap before anything even starts to look surfable.
The first real chance of a wave, and I mean *any* wave, doesn't show up until Tuesday the 28th of July. Before that, it's a total washout. From now until then, the wind is screaming out of the ENE, trashing whatever small swell is around. Wednesday the 23rd and Thursday the 24th are a complete mess – cross-onshore wind at 25 mph, turning the ocean into a white-capped mess. The swell energy is moderate (963-1090), but it's useless. The water is warm at 80°, which is about average for this time of year, but you won't be in it long enough to care.
Tuesday 28th July is the first day that might be worth a paddle at Middles/Generals. The morning is still a bit lumpy with a fresh cross-shore, but the afternoon shows a glimmer of hope. The wind swings to NE at 19 mph, turning cross-offshore, which cleans things up. The swell is 7 ft from the ENE with a period of 12 seconds – that's a solid groundswell, decent energy (1259). This is a big wave for a beach break, and with that period, it'll be fat and powerful, better for the more experienced crew. Still, it's a step up from the flatness.
Wednesday 29th July keeps that clean, cross-offshore wind going, but the swell drops a touch to 5 ft from the E (886 energy). It's still a solid option for the morning, with clean faces. Thursday the 30th shows a shift in wind to light S, but the swell is tiny and the energy is weak (413). It's a tease.
Then we hit another dry spell. From the 31st of July through to the 6th of August, the ENE wind is back, relentless, blowing 19-25 mph. The swell is a mix of weak short-period crap and over 7 ft slop that's just going to be blown out. The energy is moderate to strong (up to 1143), but the wind state is a disaster. The only break that might be interesting for a kite surfer is the beach setup on the 2nd or 7th of August, with 6 ft-7 ft of swell and strong cross-shore wind – that's a full-on wind sport session, not a surf.
The best of the entire outlook is that Tuesday 28th afternoon into Wednesday 29th July. It's the only window where the wind is clean, and the swell has some size and period. It’s not a classic, but it’s the only game in town. The rest of the run is a tough slog. The break is fairly consistent, but the conditions are just not cooperating. Don't expect this to change quickly; it looks like a pattern.
Rusty.

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 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.
