July and August are peak months, both for Mexicans and foreigners, because of summer holidays. Other important holiday seasons are "Semana Santa" (the week of Easter), and the last week of December and the first week of January (Christmas and New Year). During these peak seasons, especially beach destinations can attract huge crowds, room prices can seriously increase, and touristic services might be booked fast. Mexico City, however, can be (relatively) quiet during Mexican holidays.
