    Is there a general rule of thumb concerning the time between swells when going fishing / boating ????? We will be in a 22’ Center console.

    Am thinking of going to the Coronados this weekend, but the marine forecast says 1 foot at 7 second intervals. Kinda concerned about the lack of space between waves. But somewhat comforted by the small swell height. What dwell size and interval makes you uncomfortable?

    Some folks like when it 3 ft. at 12 sec or 4 at 15 pretty much 3 x As long as it not 4/7 and depending on your boat size also watch how windy it is as well as Gusting wind. At 7/7 Stay home

    1 foot at 7 seconds is pretty small and not very noticeable, I wouldn't worry about that. However what this forecast isn't showing is the long period south swell angled from about 165. its a big swell but because of the angle wont hit many places in SD so the surf reports wont show it however there's going to be some energy in the water offshore. If you want a better understanding of how to read bouys and swell check out swellwatch.com They give a good description of the surf conditions as well as the weather and winds. They break down the swell angle, intervals, and size. 4 feet at 7 seconds and 4 feet at 16 seconds are a huge difference.

    Your knees and lower back will be sore if you run into it full throttle, but it's nothing to worry about. However, it looks like you're looking at an inshore model. Hurricane John is pushing up a big swell offshore that will probably affect the Coronados. Swell model shows La Jolla to be flat but 6' seas a few miles out. Swell predicted to subside by Saturday evening but the forecasts change a lot and there will probably be some residual slop. Here's the NOAA offshore predict:

    SAT
    Wind variable less than 10 kt...becoming W 10 kt in the afternoon. Wind waves 2 ft or less. Mixed swell NW 1 ft and S 4 to 5 ft.

    1' swell? seriously? what are you going to do when the wake from another boat joins in and makes it a "combined sea"? :D
    Just do it.....and find out what you and your boat can do. There is no shame in turning around if you feel that you are not up to it.

    Normally, I would say Thursday and Friday look like calm seas and light wind. But the 4 to 5 feet south swell is going to ruin it. It might still be okay, but depending on the way it mixes with the normal west swell, it could lead to very bad washing machine conditions and dangerous current.

    Which is terrible, because next week looks to be a return for the wind. It's going to be a tough call.

    1 at 7 is good enough to go.

    1 is tiny. Bigger waves in a pool.

    Remember the ride home will be a lot tougher than the ride out

    Go for it. I don't sweat anything under 3 ft. I think twice if it's less than 6-8 seconds. Long duration swells are like rolling hills. It's the short duration and steep stuff that kicks your butt.

    Nobody can tell you. You have to try it out in your own boat.

    Each boat has a certain natural pitching frequency. If your boat hits waves at close to this frequency, it will start to resonate in pitch. You'll end up with the bow bouncing up as it hits the wave, then crashing down as it hits the trough. The swell period at which this happens depends on the size and weight distribution (moment of inertia) of your boat, and the speed at which you're hitting the swells.

    If you hit short-period waves rapidly but not at close to your boat's resonance frequency, the hull will basically chop through them. It might be bumpy and make a lot of noise, but your boat won't start pitching up and down like you're riding a bull.

    Likewise, if your boat is experiencing resonance, you can change your speed, or alter the boat's moment of inertia (move weight from the center to the ends, or from the ends to the center).

    That said, 1 ft is small enough that unless it's *exactly* at your boat's resonance frequency, it shouldn't be a problem.

    those hurricane swells are usually pretty spaced out.....rollers more than waves.
