I think this is something you'll need to find out & decide for yourself, because this thing hits different people in different ways. You might start paying attention to humidity and barometric pressure as well. If you can't catch your local weather report, there are plenty of online sites (and desktop widgets) that can give you that info at a glance. Some even have things like allergy and arthritis indices. More stuff to include in a pain journal (if relevant)
