You want the absolute best of both worlds. You’re looking for days hot enough to justify an ice-cold margarita on the deck of a boat, but you don’t want to suffer through the sweltering, sticky humidity of late summer. That’s exactly why March ( Cabo San Lucas weather in March ) is the sweet spot.
March marks the glorious transition from winter to spring in Baja California Sur. The skies are aggressively blue. The rain is virtually non-existent. You get abundant sunshine, minimal wind disruption in the mornings, and the perfect climate for escaping whatever cold weather you left back home.
We live on the water here, and we know exactly how the local climate dictates the action. If you prefer less planning and more cruising, this is the only guide you need. We’ll break down exactly what to expect from the skies, the ocean, and the best ways to spend your time out on the waves.
What is the weather like in Cabo San Lucas in March?
In March, Cabo San Lucas boasts average daily highs between 80°F and 86°F (27°C – 30°C) with cool, breezy evenings dropping to around 55°F (13°C). With an average of 11 hours of sunshine and almost zero rainfall, the weather is perfectly balanced for both land and ocean adventures.
The heat in March is dry and comfortable. You won’t step outside and immediately start sweating. Instead, you get a crisp, baking warmth that feels incredible after a long winter.
Mornings usually start off brisk. You might even want a light long-sleeve shirt when you first step out onto your balcony for coffee. But by 10:00 AM, the sun takes over. The temperature climbs steadily, peaking around mid-afternoon.
The evenings? They change completely. Once the sun dips below the horizon, the Pacific breezes kick in. The temperature drops rapidly. You will absolutely need a sweater or a light jacket if you’re eating dinner outside or taking an evening stroll near the marina. It’s a dynamic shift, but it makes sleeping incredibly comfortable.
Can You Swim in Cabo in March? (Air vs. Water Temperatures)
Yes, you can swim in Cabo in March, but the water is on the cooler side. The average sea temperature in the Sea of Cortez hovers around 70°F to 73°F (21°C – 23°C). While refreshing for a quick dip, longer snorkeling sessions may require a light wetsuit.
Let’s clear up a common misconception. Just because the air is 85°F doesn’t mean the ocean is bathwater. According to oceanographic data from the National Oceanic and Atmospheric Administration (NOAA), the Pacific currents keep the waters around the Baja peninsula surprisingly brisk during the early spring months.
If you jump off the back of a boat near the Arch, it will wake you up. The initial plunge feels cold. However, once you start moving around and your body adjusts, it feels incredibly refreshing against the hot afternoon sun.
The location matters, too. The Pacific Ocean side of Cabo is notoriously rough and often unsafe for swimming due to violent undertows. You’ll spend your time swimming in the protected bays of the Sea of Cortez.
If you run cold, ask your crew for a shorty wetsuit before you jump in. It makes a massive difference if you plan to float around looking at tropical fish for more than twenty minutes. If you’d rather stay completely dry while still enjoying the ocean views, booking private yacht charters for Spring Break is the perfect workaround. You get the sun, the salt spray, and the luxury, all without forcing yourself into chilly water.
Top Water Activities to Book in Cabo This March
March weather dictates the action. The cool mornings mean calm seas, while the afternoon winds kick up the chop. Because the climate is so cooperative, you have endless options when mapping out things to do in Cabo San Lucas. Here are the top on-the-water experiences you need to lock in.
Peak Season Whale Watching
You are arriving at the absolute perfect time. March is the grand finale of the whale migration season. Thousands of Humpback and Gray whales have spent the winter in the warm Mexican waters mating and giving birth.
By March, the calves are growing stronger. The mothers are active. You aren’t just seeing a distant spout of water on the horizon; you’re seeing massive, 40-ton creatures launching themselves entirely out of the water. The surface behaviors—breaching, tail-slapping, and spy-hopping—are at an all-time high right now. Conservation groups like the World Wildlife Fund (WWF) note that these warm waters are critical for the early development of the calves before they migrate back up north.
You do not want to miss this. Book Cabo whale watching tours in March for the early morning. The wind is low, the water is glassy, and it makes spotting these giants significantly easier.
Morning Snorkeling at Pelican Rock & Lovers Beach
If you want to see underwater life, timing is everything. We always recommend morning departures for our guests. Why? The wind hasn’t picked up yet, meaning the water is calm and the visibility is crystal clear.
Pelican Rock is a massive underwater cliff face teeming with life. You drop in, and suddenly you are surrounded by massive schools of Moorish Idols, vibrant parrotfish, and often, sea lions zipping past you.
Because the water is hovering around 72°F, the morning sun on your back while you swim feels fantastic. If you want a seamless experience where the gear and the drinks are handled for you, securing a trip for snorkeling at Pelican Rock guarantees you hit the best spots before the mid-day crowds arrive.
Sunset Sails to El Arco
The golden hour in Cabo is legendary. The harsh daytime light softens, turning the jagged rocks of Land’s End into deep shades of orange and red. The roar of the boat engine cuts out as you drift near the famous Arch, watching the sea lions bark on the rocks.
But remember what we said about the temperature drop? It happens fast out on the water.
When you book sunset sails to El Arco, you start the trip in a t-shirt and sunglasses. By the time you are heading back to the marina under the stars, the wind is whipping and the air is hitting 60°F. Bring a light windbreaker. You’ll thank us later when you’re comfortably sipping tequila on the deck instead of shivering inside the cabin.
What to Pack for a Cabo Boat Trip in March
Packing for the transition season requires strategy. You are dressing for two completely different climates depending on the time of day.
- Reef-Safe Sunscreen: The sun is intense, even if the breeze makes you feel cool. Protect your skin and the reefs.
- Strategic Layers: Pack a lightweight, long-sleeve UV shirt for the boat. Throw a windbreaker or a cozy sweater in your bag for the evening hours.
- Polarized Sunglasses: This is non-negotiable. Polarized lenses cut the glare off the water, making it ten times easier to spot whales and dolphins swimming just below the surface.
- A Light Wetsuit Top: If you own one and plan to snorkel heavily, bring it. Otherwise, request one from your charter.
Many first-time visitors also wonder about local security when planning their packing and itinerary. If you’re questioning is Cabo San Lucas safe to walk around at night with your gear, the answer is a resounding yes, especially in the main tourist corridors and marina areas where the nightlife thrives.
