The best time for hanging Christmas and outdoor holiday lights is before your weather turns wet and cold.
Not only is it easier and more comfortable to work outdoors in mild weather, but it is also safer. Safely climbing ladders
and working along the eaves of a roof can be a dangerous challenge in bad weather.
Even if you don’t actually hang your light strings well ahead of the season, you can get
much of the preparation done, such as running outdoor extension cords, installing hooks and hangers, and so forth.
