Quick Answer
Los Cabos benefits from a desert climate that makes it one of Mexico’s most reliably sunny destinations - over 350 sunny days per year. October through June is the safe window; explore what Los Cabos offers before booking and reserve accommodation well ahead for any December to March visit.
Season Overview
Los Cabos sits at the southern tip of the Baja California Peninsula, where the Pacific Ocean meets the Sea of Cortez. The Baja desert climate means rain is minimal for most of the year - the rainy season (July–September) is unusually short for Mexico.

Peak Season: December to March
Los Cabos’s luxury resort corridor along the Corridor (the 33km stretch between Cabo San Lucas and San José del Cabo) operates at maximum capacity from December to March. This is the driest, sunniest, and most comfortable period - temperatures range from 22–29°C with almost no rain. Christmas and New Year pricing rivals the Caribbean: five-star Corridor resorts charge their highest annual rates, and the marina in Cabo San Lucas fills with large yachts.
Whale watching is a major draw from December through March. Gray whales breed in the Baja lagoons (Scammon’s, San Ignacio, and Magdalena Bay), and humpback whales are frequently spotted in the Sea of Cortez near Los Cabos. Whale watching tours from the Cabo San Lucas marina run daily and typically guarantee sightings in January and February.
March brings Spring Break crowds to Cabo San Lucas specifically - the downtown marina area and Medano Beach become very lively. San José del Cabo, 33km east, remains quieter and is a better base for travellers seeking a calmer atmosphere.
Shoulder Season: October, November, and April
October and November are Los Cabos’s best-kept value window. Hurricane season winds down rapidly after mid-October, and by late October conditions are almost indistinguishable from January. Hotel rates in the Corridor haven’t yet reached Christmas levels, so you can access luxury resorts at significantly lower prices. The Sea of Cortez is warm (25–27°C) for snorkelling and kayaking around the famous El Arco arch rock formation.
April is good for budget-conscious peak-season visitors. Spring Break has ended, rates moderate from March highs, and the sunshine is reliable. Temperatures start climbing toward 30°C, which some find more appealing than the cooler January conditions.
Off Season / Rainy Season: July to September
The Baja desert receives very little annual rainfall, but what rain does fall comes concentrated in July through September - typically via tropical storms from the Pacific. Hurricane Odile (September 2014) caused catastrophic damage with 200km/h winds, so the risk is real even if rare. Travel insurance with storm cancellation cover is essential for any booking in this window.
The positive side: June is largely fine, July mornings are often sunny before afternoon heat and occasional storms, and the Sea of Cortez reaches its warmest temperatures (27–29°C) making snorkelling and diving outstanding when conditions allow. Serious travellers who monitor Pacific storm forecasts and visit in June or early July often find excellent conditions at a fraction of peak pricing.
