Weather in Formosa changes the feel of the city because this is a place where comfort depends on more than the number on a forecast.

What makes June stand out is balance. It is not necessarily perfect every day, but it usually gives travelers the best combination of outdoor comfort, manageable weather risk, and enough flexibility for a first-time trip.
