Los Cabos sits at the southern tip of Mexico's Baja California Peninsula, a dramatic strip of desert where cactus-studded hills tumble into the collision point of the Pacific Ocean and the Sea of Cortez. The region is really two places in one: Cabo San Lucas draws sport fishers, sunset cruisers, and nightlife seekers, while San Jose del Cabo, twenty minutes north, offers colonial charm, a thriving gallery district, and a quieter, more authentically Mexican pace. Between them lies a corridor of world-class resorts, golf courses designed by the biggest names in the game, and a dining scene that earned Los Cabos a place in the first Michelin Guide to Mexico. From December through April, humpback and gray whales migrate through these warm waters by the thousands, making it one of the planet's premier whale-watching destinations.
The best time to visit Los Cabos runs from late November through late April, with the sweet spot falling between December and March. This window delivers warm but comfortable daytime highs, virtually zero rain, and the full whale-watching season, when humpbacks and gray whales feed and nurse their calves just offshore. You'll also catch the San Jose del Cabo Art Walk on Thursday evenings, the weekly organic farmer's market at the Shoppes at Palmilla on Fridays, and the liveliest stretch of the restaurant and nightlife calendar. The tradeoff is peak-season pricing and heavier crowds, especially around the winter holidays and March, the busiest month of the year. If you want to dodge the crowds and save on accommodations, October and early November make a strong shoulder-season alternative, with warm weather, world-class fishing tournaments, and significantly fewer visitors.
Spring in Los Cabos, Mexico
By March, Los Cabos is at the height of its social calendar. This is the busiest month of the year for tourism, and the energy is palpable along the Cabo San Lucas marina, where whale-watching boats head out every morning and sport-fishing charters stack the docks by afternoon. The Festival de San Jose, an 11-day celebration honoring the city's patron saint, typically wraps up around mid-March with parades, live music, and food vendors selling fresh tamales and candied pumpkin along the downtown streets. Afternoon highs average 86.8°F (30.4°C), warm enough for a full day at Chileno Beach or Santa Maria Bay but still comfortable under a breeze. Rain is essentially nonexistent during these months.
As April rolls in, the whale-watching season winds down, with the last humpbacks beginning their 6,000-mile journey back to Arctic feeding grounds. Crowds thin noticeably after Easter week, and accommodations start to become more reasonable. May is technically still spring, and temperatures keep climbing, but it remains dry and sunny, making it ideal for snorkeling at Cabo Pulmo National Marine Park or playing a round at one of the championship courses. Mornings start mild at 64.3°F (17.9°C), perfect for an early tee time or a walk through San Jose del Cabo's art district before the afternoon warmth sets in. Pack reef-safe sunscreen and a wide-brim hat, since cloud cover is scarce.
Summer in Los Cabos, Mexico
Summer is Los Cabos in slow-burn mode. Seasonal highs average 93°F (33.9°C), and humidity climbs into the 40-50% range, making outdoor sightseeing more taxing by midday. In early August, peak heat pushes highs to 95°F (35°C) with overnight lows of 79.3°F (26.3°C), so even evenings don't offer much reprieve. This is the one stretch of the year when a brief afternoon shower is possible, though significant rain remains extremely rare. Tourism drops off considerably, which means lower rates at the corridor's luxury resorts and shorter waits at popular restaurants.
The payoff for enduring the heat? June brings the Los Cabos Open of Surf to Zippers Beach on Costa Azul, a major surfing and music festival that fills the shoreline with competitors and spectators. The ATP Tennis Open follows in July, drawing world-class players to the Cabo Sports Complex. Sport fishing remains excellent, with marlin, tuna, and dorado running strong through these warmer months. Lows settle to 77.1°F (25.1°C) at night, still quite warm, so lightweight clothing and plenty of water are essential. The long summer days, with the sun not setting until after 7pm in June and July, give you ample time to hit the beach early and retreat to an air-conditioned spa by afternoon.
Fall in Los Cabos, Mexico
Fall is bargain season in Los Cabos, and serious anglers know it. September is the quietest month of the year, with tourism at its absolute lowest, and accommodations are priced accordingly. The fishing calendar heats up starting in October with the Los Cabos Billfish Tournament, followed by the legendary Bisbee's Black and Blue Tournament, one of the richest sportfishing competitions in the world, which draws international teams to compete for massive payouts at the Cabo San Lucas Marina. Highs average 89.3°F (31.8°C) and humidity peaks in September before gradually easing. Rain remains almost nonexistent across the season.
By November, the region's character shifts. Temperatures begin their descent toward the comfortable winter range, and the visitor count ticks upward. Day of the Dead celebrations around early November bring Calavera costume contests, live music, and festive dinners across resorts and restaurants. The Los Cabos International Film Festival also takes place in November, attracting filmmakers and cinephiles to screenings and industry events. The San Jose del Cabo Art Walk resumes its Thursday-evening schedule, with gallery openings along Obregon Street. Lows drop to a more pleasant 70.5°F (21.4°C) as the season progresses, and the organic farmer's market at the Shoppes at Palmilla kicks off its weekly Friday sessions. Bring light layers for November evenings, when a gentle sea breeze can make open-air dining surprisingly refreshing.
Winter in Los Cabos, Mexico
Winter is when Los Cabos truly comes alive. The whales arrive by mid-December, and from then through March, humpback and gray whales breach, spout, and nurse their calves within sight of the coastline. Peak whale activity falls between January and March, with February offering the highest odds of close encounters. Morning boat tours depart from the Cabo San Lucas Marina daily, and you can often spot spouts from resort balconies and Pacific-side beaches like Cerritos without ever stepping on a boat. Afternoon highs of 79.9°F (26.6°C) feel practically perfect, a welcome relief from the summer furnace.
This is also the second-busiest season for tourism, particularly around the Christmas and New Year's holidays and into February. The San Jose del Cabo Art Walk runs every Thursday evening, filling the gallery district with wine, live music, and local artwork. The weekly farmer's market at the Shoppes at Palmilla offers fresh local produce, artisanal pastries, and regional seafood each Friday. Evenings cool to 58.4°F (14.7°C), comfortable enough for a light jacket if you're dining on an ocean-facing terrace after sunset. Rain is essentially zero during these months, and every day brings clear blue skies, making it the most reliable stretch of weather in the entire year. Book whale-watching tours for early morning, when seas are calmest and the soft light makes for the best photography.

Travel Tips & Safety for Los Cabos, Mexico
Los Cabos International Airport (SJD) serves both Cabo San Lucas and San Jose del Cabo, with the taxi and shuttle ride to most corridor hotels taking 20 to 45 minutes depending on your resort's location. Many visitors pre-book airport transfers through their hotel or a reputable shuttle service. Tipping in restaurants follows a similar convention to the United States: 15-20% is standard at sit-down establishments, and a small tip for bartenders and hotel staff is appreciated.
Most beaches in Los Cabos have strong currents and are not safe for swimming. Stick to designated swimmable beaches like Medano (Playa el Medano) and Chileno Beach unless you're an experienced ocean swimmer. Drink bottled water, stick to well-reviewed restaurants for street-food adventures, and keep valuables in your hotel safe rather than carrying them to the beach. If you're visiting during the summer months, stay hydrated aggressively, as heat and sun exposure at these latitudes can be intense even on overcast days.
