I think this is like asking a Texan how they cope with rain (turn the wipers on) or heat (turn the A/C on). Imagine getting the same puzzled look.

Rain/snow: wear a coat, optionally overtrousers.

Hot: go slower if you normally race in, and it doesn't get much above 20 degrees anyway.

I walk two miles from my house to my office in Philadelphia. When it rains, I wear a raincoat. When it snows, I wear boots. When I first moved to the city, I took the subway during inclement weather, but after about two years, I came to just adapt to walking in all weather. In the summer, I'd take a few minutes to cool down. Other people, who biked, brought a change of clothes - but in our second building, we have a shower, and some guys used that as well.
