Tahitipresse, a French Polynesian website, displays virtual snow for Christmas.
Reminds me of the French African schools where African children studied in textbooks from the metropôle about "Nos ancêtres, les Gaulois." Translation: "Our ancestors, the Gauls."
Personally, I'd prefer to think about a Tahitian Christmas, with canoe races and barbecued fish. I wonder if there's even a word for "snow" in Tahitian.
For something more authentic, you can hear a bit of a Tahitian Christmas song, "Noela Alleluia," here.
