Cabo San Lucas Weather in March: What to Expect

What is Cabo San Lucas weather like in March?

March in Cabo is generally warm, dry and sunny. It’s a good month for beach time and outdoor plans, but evenings can feel cooler than the afternoons, and the ocean is still on the cool side.

For temperatures, climate sources don’t give one consistent average. One source reports a March average high of 74°F (24°C) and low of 64°F (18°C); another reports 86°F (30°C) and 59°F (15°C). A third describes typical daytime highs around 81°F to 86°F (27°C to 30°C). Treat these as different climate estimates, not a forecast for your travel dates.

Those reported averages come from different sources and methods: CaboSanLucas.net’s monthly weather guide, Time and Date’s climate averages and Atlas Ranger’s month-by-month guide. Time and Date notes that its averages use reports from La Paz, 147 kilometers from Cabo San Lucas, so local conditions can differ.

Rain is unusual in March, and the broader March-to-May stretch is described as the driest and sunniest part of the year. For another month-by-month comparison, see our Cabo weather guide.

Is March a good time to visit during spring break?

For warm, mostly dry weather, yes. For a quiet trip, not necessarily. March is part of Cabo’s peak season, and spring break makes the marina especially busy and lively. It can also be loud, particularly if you’re staying near the action.

If you want restaurants, boat tours and Médano Beach within walking distance, staying near downtown or the marina may suit you. If late nights and spring-break crowds aren’t your thing, look at a different area or consider February or April, which are suggested as alternatives with similar dry, sunny conditions and smaller crowds. Our guide to where to stay in Cabo compares the main areas.

Spring break dates aren’t specified in the research here, so check the calendar for your travel year rather than assuming the crowds peak on the same dates every March. For a closer look at the party scene and planning considerations, read our Cabo spring break guide.

How windy is Cabo, and can you swim?

Time and Date lists March’s average wind speed as 17 km/h, or about 11 mph. That’s a useful baseline, not a promise that every beach or boat trip will feel the same. The same source lists June as the windiest month, with an average of 23 km/h, so March isn’t the annual peak in its data.

The sea is cooler than it is later in the year. March sea-temperature estimates sit around 70°F to 71°F (21°C to 22°C), and NOAA satellite data cited by CaboSanLucas.net identifies March and April as the coolest-water months. You may be happy to swim, but don’t expect bath-warm water. A rash guard or wetsuit top is practical if you’ll snorkel or dive.

For a more protected swim, Médano Beach on the Sea of Cortez side is described as calm and suitable for swimming and watersports. Pacific-facing beaches, including Solmar Beach and the stretch near the Arch, can have powerful rip currents and are often not swimmable. Check the flags and signs before entering the water, and use our swimmable beaches guide to plan your beach days.

March is sunny enough that a hat, sunglasses and reef-safe sunscreen make sense. Pack light clothes for daytime and a light layer for cooler evenings or time on a boat. Those are more useful than packing only for hot afternoons.

Can you still see whales in March?

Yes. March falls within the gray and humpback whale season off Cabo, which runs from mid-December to mid-April. Boat tours operate daily during the season, and whales are sometimes visible from shore. Sightings aren’t guaranteed, so treat a tour as a chance to look, not a promise of a close encounter.

March is a good fit if you want to combine whale watching with warm, dry weather. It’s also near the end of the season, so if seeing whales is central to your trip, don’t push the visit too late into spring. Read our Cabo whale-watching guide for more on the season.

What should you plan for before you go?

Think of March as a trade-off: comfortable daytime weather and little rain, with busier popular spots and cooler ocean water than in summer. Pick your base based on the trip you want, not just the forecast. A marina-area stay fits a social, walkable trip; a quieter location may be a better match if you want fewer spring-break sounds outside your room.

• Pack: breathable daytime clothes, a light evening layer, sun protection and a rash guard or wetsuit top for time in the water.
• Choose your beach carefully: Médano is the more protected swimming option mentioned in the research; check local flags and signs at any beach.
• Leave room for wind: the monthly average gives a rough guide, but it doesn’t tell you what conditions will be on your exact beach or boat trip.
• Keep expectations realistic: warm air doesn’t mean warm water, and whale season doesn’t guarantee a sighting.

Our take: Cabo in March is a strong choice if you want dry, sunny weather and don’t mind sharing the marina with spring-break visitors. If you want the same broad weather pattern with fewer reported crowds, compare your dates with February or April before booking.
