Insider timing tips

  • The 'green season' (May-October) offers lush scenery and fewer crowds, but be prepared for daily downpours that can impact temple access.
  • While the dry season (November-March) is ideal for weather, expect peak crowds and prices, especially around Christmas and New Year.
  • Shoulder months like March and October offer a balance: decent weather with slightly fewer crowds and lower prices than peak season.
  • The heat in March and April can be extreme; plan temple visits for early morning or late afternoon.
