Brazilian's impression on the united states(i have never been there and this is based on nothing)

The gigantic swamp cooler sitting next to us bringing ice cold water straight from Alaskaa and Siberia is a big factor there.

Water, mainly.

Northern hemisphere currents cycle clockwise, which means on the west coast the current is bringing water from the north down. It's why the water is so fucking cold there, but it keeps temperatures cooler than they would be.

On the east coast we get water coming from the south up, so our water is much more comfortable. It also keeps the temperature warmer than it would be otherwise.

This effect is true for all east/west coasts in the northern hemisphere, and inverse in the south. It's why the English isles are as cold as they are.

Water has a lot of thermal mass too, so just being near water has a huge effect on your local climate. It keeps things much more stable. It's a lot less likely to have big swings in temperature.

Could not agree more, we also have states with directions on their names, but here the ones we don't take seriously are only the north ones. Rio Grande do Norte, get lost.

Especially those from north Montana.
