Cabo San Lucas Weather in March

March keeps the dry season going with barely any rain, 0.2 days on average, close to the driest reading of the year, while highs climb to a warmer 78.8°F and the sea starts its slow recovery to 71.7°F.

Humidity drops to 58%, the lowest of the year, making March arguably the most comfortable month of the year for hiking, golf, or any activity away from the water.

This is peak humpback whale season in Cabo, March is widely considered one of the two best months (alongside February) for consistent, close sightings, with calves often visible alongside their mothers in the calmer waters of the bay.

Spring break brings a real crowd increase to Cabo starting in mid-March, though it's generally less chaotic than Cancún's version, Cabo's spring break scene concentrates more around specific resorts and Medano Beach rather than overwhelming the whole destination.

No hurricane activity is recorded historically in March, hurricane season doesn't begin until June here, so weather-safety-wise this remains an easy month.

Sportfishing picks up as waters warm, with striped marlin a common catch this time of year for charters heading out from the marina, alongside the tail end of the winter's dorado runs.

El Arco and Land's End boat tours run in excellent conditions through March, with calm seas making the classic photo-op trip to see the sea lion colony and the famous rock arch a smooth, pleasant outing.

Golf remains outstanding through March, with mild temperatures and minimal wind compared to what typically arrives by late spring.

Compared to the peak of summer, March offers dramatically cooler, drier conditions with the added draw of whale watching, the tradeoff is spring break crowds in the back half of the month and cooler swimming water than summer visitors get.

Pack for warm days and cool mornings and evenings, plus reef-safe sunscreen; the desert sun is intense even with comfortable air temperatures.
