Your biggest concern will be the change in humidity. The cold weather will dry you out if you are used to living in a warm, moist climate. Make sure you get some nasal moisturizers (they are sprays but w/out drugs, just saline, etc.) and stay hydrated. If you think cold water triggers your sinusitis, then drink room-temperature water. Stay inside as much as you can when it is very cold. Good luck.

I have had sinus trouble for a long time but have been getting some relief from taking generic Claritin that I get from Sam's Wholesale club. I take it every night.
I also take Grape Seed Extract Capsules when I start feeling or seeing signs of trouble - runny nose or green mucus. I take 2 in the morning and 2 at night for about 3 days and that seems to really help.
