Best Time
The best time to visit León runs from June to September, since it is the warmest and sunniest period of the year. Sometimes it can be hot, while in other circumstances, nights can be cool or even cold, so it can be useful to bring a sweatshirt or sweater and a light jacket for the evening, and maybe gloves and a wool hat, which take up little space and can be useful on colder nights.
If you fear the heat, you can choose the periods from mid-May to mid-June and from mid-September to mid-October (when, however, it rains more often, and it gets more easily cold at night).
