Why visit Sintra during Apr–Jun, Sep–Oct?
The forests are lush and vibrantly green; wildflowers carpet the hillsides. Weekends get busy but weekday visits are peaceful.
Shoulder season (Mar, 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–Feb, 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.
