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.
The Weather Hut explains that barometric pressure measures the weight of air in the atmosphere above as a pressure.. Changes in this pressure correspond to changes in weather. Electronic barometers now are available in addition to older-style units that use a needle and dial to track pressure changes.
