Why visit Mont Saint-Michel during May–Jun, Sep–Oct?
Variable — sunny days alternating with showers. April-May can be cool but with crisp light; June is pleasantly warm.
Shoulder season (Apr, Jul–Aug, Nov) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Mar, Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
