it's cold here too! Antigua is much colder - about 20 degrees - than the coasts because it's in a high valley. so it's cold enough here to need a heater but they don't have any type of central heating. if you don't have a fireplace it's blankets and soup.
the expats are all saying it is much colder this year so i guess it's a colder winter for everyone. i'm not complaining as you can drive an hour to the coast or just out of the valley and it warms up very quickly.
