As a tropical island, I would HOPE there would NEVER be a snow storm in the menu of seasons. Rainy season..that works, makes farming a lil mushy, but if they didnt harvest quick the crops could spoil, or they plant something different for that season, hurricane season would definitely keep the builders busy and therfore heap the skill points for them. In addition there would be lots of cleanup duties to boost everyones building skills on their way to that illustrious elder status. Hot season could present its own problems with either excess algy in the lake or a percentage of the fish caught being sick and not edible. Of course the farmers would have to work harder, between fishing for good fish and keeping extra water on the crops so they didnt wilt and die.
