I am wanting to travel to Iceland to see the Northern Lights this year. I was thinking about Nov/Dec time (as I have heard that Oct thru to March is a good 'window' for this). As I am travelling from Australia I want to be fairly sure that I see them at least once in around 2 weeks in Iceland. (I will base myself in Reykjavik - but do trips from there to other parts of Iceland) What are my chances?....Or would early 2013 be a better time (March?).....How cold is it in Nov? ....Cheers!
