Weather is some of it, but that isn't close to the biggest appeal of those cities at all. Many of us like SF and LA way better NYC, and NYC weather really isn't that bad (from my limited 3 month stay there).

If it's the past 3 months, those aren't the bad ones. they're a bit hot. it's the next 5 to watch out for.

they're not that bad, but they're not everyone's cup of tea.

It was summer, and it wasn't a nice one. But NYC seemed fine in terms of weather for me.

But I really didn't like the culture, the roads, the housing, the way people drove. I'm just not suited for east coast life.
