It appears that hot weather results in blood pressure decrease during the daytime, but an increase in the top number at nighttime. If you suffer from high blood pressure, you might want to check with your doctor and investigate the effect that hot weather could have on your blood pressure. There are many factors to consider: age, gender, degree of high blood pressure, climate where you live, and how long youâve suffered from high blood pressure.
In fact, you can have a very nice weather in a high pressure zone, with clear sunny sky and little wind, but during daytime, the pressure drops a little to climb up again during the night. That is a normal diurnal variation of pressure; when it is hot, air rises and pressure drops a bit. It is not the drop in itself but the rate of fall that is the most important point and that's why some people have barographs that register the pressure over time. An old seafarer's rule is that a pressure fall of ten millibars (today, called hecto-Pascal) in eight hours is a certain sign of a gale force wind coming in. And that is the only thing that is 100 percent certain in meteorology; a pressure fall must be followed by a wind of air trying to fill again the lower pressure.
