Puerto Peñasco in December

October through April is prime time. Temperatures hover in the 70s and 80s, perfect for beach days without the scorching heat. This is also peak season, so expect crowds and higher prices, especially during spring break in March. May and September are shoulder months with great weather and fewer people. Hotel rates drop significantly, and you'll have more beach space to yourself. Just avoid late September if hurricanes are tracking up the coast. Summer is brutal. Temperatures regularly hit 110°F, and many restaurants close or reduce hours. The upside? Rock-bottom prices and empty beaches. But seriously, it's hot enough to fry an egg on the sand. Winter brings the snowbirds — retirees escaping cold climates. December and January see the most American visitors, creating a unique cultural mix. Book accommodations early during these months.
