Crazy Cold Weather for Thailand

Thailand's less humid time of year is normally cooler during the evenings and early mornings where the temperature is at a comfortable 60-70 degrees. By mid-day, it is a warm 80-90 degrees. The only places that are really cold, are up in the mountains of north, where the temperature can get down into the 30's and 40's.  This year, however,  a cold spell hit downtown Chiang Mai and its suburb where I live.  The people around here had never experienced such cold. For a week, we were in the 50's degree all day with no sunshine. Thai homes do not have heaters. So, what do we do?  We bundled up like Eskimos, where ever.we go, indoor and out. We have hot chocolate in the mornings and wear thick coat to every meal and to every service. It was a crazy weather week!
