Most boating accidents happen during nice weather quite on the contrary to what most people believe.
The reason for this is that when it is nice weather, more people go out on the sea.
People want to go water skiing and speeding always carry a high riskfactor.
Some people out swimming also get hit by boats. Divers are at high risk as a lot of them do not use diver-flag and most of people out speeding just does not know what a diver flag is, so they drive over to it, kiling the diver in the action. (Could explain why so many divers do not use it.)
There are accidents due to windy weather as well, but not that many as most people are safe ashore when the wind begin to get troublesome.
Thunderstorms and lightning... Not likely that you would want to be out at sea in this weather. The chances are that the lightning would not hit you anyway, but it would be one hell of an experience in a small boat. (I have experienced this.. thought it was fun at the time, but my mate was scared stiff.)
Most boating accidents occur when the weather is calm and clear and winds are light. The main cause of boating accidents is human error.

Typically a sharp drop on the barometer and warm, moist air ahead of the storm front.
