In my part of the US, nicer private schools and daycares tend to act that way, but cheaper ones or public schools schedule less of that time to begin with and are quick to replace that with indoor activities if there's a light drizzle or it's a little cold outside. Perhaps counterintuitively, public schools seem much quicker to bow to the preferences of one or two nutty parents ("little Johnny was COLD at recess! You can't go outside when it's 35°F, that's unsafe!") than private schools do.

Also, public schools have responded to No Child Left Behind legislation, in part, by drastically cutting recess time, including in very early grades—which, AFAIK given the state of the art in learning research, might actually be counter-productive, but a key sentiment driving all US behavior is that one must always be able to say that one has "done something", even if that something was worse than doing nothing, and that it's preferable to so something that an uneducated person would think looks like it should help based on gut feeling, over what experts say would help.
