Why visit Santiago during Mar–May, Sep–Nov?
Warming up with occasional rain showers. Parks bloom and the Andes still carry snow.
Shoulder season (Feb, Jun, Aug, Dec) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan, Jul) 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.
