Spring (April-May) offers mild temperatures (15-20°C) with blooming gardens and fewer crowds. Summer (June-August) brings warm weather (22-28°C) but peak tourist season with higher prices. Autumn (September-October) combines pleasant temperatures (16-22°C) with grape harvest season and wine events. Winter (November-March) is cool (5-12°C) with occasional rain but significantly fewer tourists and special holiday markets. Avoid August for lowest prices and April-May or September for ideal weather and manageable crowds.
