Ah, August...

You're right about coastal vs. inland, you can even tell a difference just by going 20 miles inland instead of being on the coast, though going to the center of a continent is a much more dramatic difference of course. Oceans moderate temperatures, so the highs aren't as high and the lows aren't as low -- so coasts don't usually have the massive, rapid temperature swings of midcontinent areas. Ocean breezes also help keep things cooler.

As for snow, the biggest difference there is where the mountains are. Where the mountains are, there will be the most snow. So in Maine, it's the central mountains (end of the Appalachians) that get the most snow, while the flat coastal regions (where I live) get less.

At school I'm a little bit inland (like 30 miles), but it's a bit north of home, so it mostly cancels out, I think...
