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.
To better illustrate how the barometric pressure is affecting my pain levels, I have included some charts to go with the numbers. You will see that when the barometric pressure is high (above 30.00) I have no back pain. When the barometric pressure is low or drops below 30.00, my pain level increases. Out of all the meteorological reading I.E. Temperature, Humidity, Dew Point, Wind Speed and Direction, Barometric Pressure, and even the changes in Seasons, the one constant reading affecting my pain levels is the barometric pressure.
