With its growing popularity, Los Cabos has a high season that seems to keep gaining months. It's been said that high season is now October through July, though the crowds are a bit more manageable in October and after mid-April. Summers can be scorchers in this desert landscape, reaching temperatures that climb into the 90s and above. Book early—often as many as six months in advance for top holidays such as Thanksgiving, Christmas, New Year's, and Easter, and at least three months in advance for other high-season stays.
