Start with the region
National weather averages can hide major local differences, especially in mountainous, coastal or elongated countries.
Match the season to the activity
Beach time, hiking, city sightseeing, wildlife, winter sports and festivals can each favour different windows.
Crowds and availability are another season
Peak weather can also mean higher demand, sold-out transport or reduced flexibility.
Check current conditions before committing
Seasonal norms do not predict a particular week's heat, storms, fires, closures or transport disruptions.
Verify before you go. Weather, entry rules, advisories, transport schedules, prices and local conditions can change. Use this page to structure your decision, then verify the current details that affect your specific trip.
