I recently spent Christmas and New Year in Argentina, Uruguay and Brazil.
Christmas in hot climates is pretty surreal, seeing decorations in sweltering sunshine or against bright blue skies.
Christmas lights and decorations vary from pretty and good to ridiculous and tacky. Overall though, for us in Europe, they light or cheer up the darkest time of the year and bring a little glitter to the gloom.
Not so in the southern summer, but they were rather entertaining and fun for me to see how Christmas traditions translate in different climates.
My favourite sight - which I saw from a car so no time to photograph - was of a Christmas tree on a beach, made of clear and green discarded plastic bottles.
