Traveller notes on Lake Tekapo in September
Other months in Lake Tekapo
Lake Tekapo's forum calls January warm and pleasant, but flags a real catch for the stargazing the town is famous for — summer's short nights mean less darkness to work with, and regulars say autumn and winter actually deliver the longer nights and often clearer skies. A commercial tour isn't required either: walking or driving to the lake edge after dark gets much the same view for free.
