Hey mike...First off, good luck with your dives and welcome to the wonderful world of diving!
I'd like to take a stab at this question for ya.
Since I started diving in June (you old guys can laugh now if you'd like)
, I've looked at
chuck's conditions page and the weather forecast. The forecasts he feeds from there are color coded (they are products of NOAA and the Navy if I'm not mistaken) and a guide to what they mean is on that page. If you go by the colors, Breakwater has been pretty calm most days even when you see green on either the swell model or the wave forecast. It is usually light blue or dark blue (meaning fairly calm--there is actually a number associated with this). Now Chuck or any other of the more experienced guys are more than welcome to flame me on this, but looking at the way Monterey is layed out, Breakwater should usually be pretty calm because it sits on the "protected" side of the peninsula. Meaning that the South of Point Pinos/Point Joe (probably including it) is exposed to the open ocean, but Breakwater is not (or doesn't take as much wave energy, because of this protection), so on a normal day, Breakwater is mostly calm. All that being said, the ocean changes from day to day anyway, and you could have a forecast for 6-8 foot waves/swell and go look at it the day you dive and it's as flat as a board. I think you'll be fine whatever the conditions at Breakwater. Your instructor would let you know or should let you know if he/she thinks the conditions are unsafe and that you should dive another day. Winter time, from what I hear, seems to be when you get a lot of undiveable days because of winter storms.
Anyway, once you're certified, you're more than welcome to join us at one of our scubaboard events that seem to be happening somewhat regularly now.
It's a great way to meet other divers. Just keep diving after you get certified.
Also, ask for a dive buddy on Scubaboard once you get certified, if you're having trouble finding people to go diving with. And you're more than welcome to come diving with me and my buddies.
On your nervousness, I was nervous too during my open water dives and even after that for about the first several dives (probably more like the first 5-6). Maybe nervous isn't the right word, but I lacked the confidence to go out there and plan a dive with a buddy. I still felt like I needed that instructor near by if something happened. The more you dive though, the more comfortable you get in the water. And the more you dive, the more your comfort zone expands of what you're able to do in the water as well (i.e. deeper dives, wreck dives, tech dives, etc...).
Again, good luck and maybe we'll see you at the Breakwater.
