We just visited in November and really enjoyed that time of year. It is low season so you won't find so many tourists, which can result in a very real experience. The weather was definitely variable - some days it was hot enough for a t-shirt and jeans, other days I needed a heavy trenchcoat and it rained.
Q. What effect does the barometric pressure have on humans? Can it cause headaches and other discomforts? A. Differences in air pressure because of the weather or changes in altitude can have noticeable effects on the human body, though some people are more sensitive than others.
But barometric pressure often drops before bad weather sets in. This lower air pressure pushes less against the body, allowing tissues to expand -- and those expanded tissues can put pressure on the joint. It's very microscopic and we can hardly notice, except that we have these sensations, Jamison says.
