My sinuses go crazy for a bit every time the barometer changes. Here or in the US. I also have a reaction when the palm trees put out their fruits, so I have them all cut off once they come out. Seems to help.
But then again, my sinuses go crazy when I am in the US as well, it's mostly dependent on the amount of humidity. If it stays the same for a few days, they will adjust, but when that changes, so do my sinuses.
