Last XMAS was definitely cold. We were in long underwear under jeans, long sleeved shirts, jackets and gloves. I also wore 2 pair of socks with my tennis-shoes to keep my feet warm. We purchased and used hand-warmers from Wal-Mart. Definitely not sandals weather! Now, it could be warm, but the weather is so variable at that time of year, I'd definitely bring along some warm shoes.
