Which region on earth is characterized with little temperature change throughout the year?

Your arthritis will feel better closer to the equator!!

Aradlaw, At the North Pole, the summer average is around the freezing point (32°F/0°C), but the winter average is minus 40. Huge difference, even though both seasons are "cold." At the Equator, seasonal temperature differences are small.

I thought it was always cold at the poles.

Can't tolerate the Coldness where Santa lives in the North pole

I knew that the northern area is cold when the south is hot so between them it must be always moderate.

it doesn't state, what the average temperature is, my guess is hot, and humid, hard pass!

Little diff through seasons.

Aradlaw, you are right. The only option that doesn't really fit the question is the meridian.
