For your 13th birthday party in winter it would be a good idea to have a gathering at home. Invite as many people as you like. Another good way to have a 13th birthday is to have a themed party like Hawaiian luau or Disney characters.

A luau for a 13th birthday party in February may not be ideal in colder weather. However, blow up palm trees and plenty of sand can make the party fun.
