This would be easier if you showed us a sample of your data and what commands you are using. Without we need to guess.
Probably your month variable is being turned into a factor somewhere and the default for factors is alphabetical. The best solution depends on how/where/when your months are being factorized. You need to control the factorizing, maybe turning them into some type of date object instead of a factor, or create the factor, but specify the order that you want. -- Gregory (Greg) L.
