Is It Too Cold To Visit Cabo In January For A Beach Vacation? Here’s What Travelers Are Saying

Share The Article

It’s the question that pops up on travel forums every single winter. A traveler books a January trip to Los Cabos, expecting tropical heat, and then starts reading reviews about “chilly” water and cool nights.

Panic sets in. Did I make a mistake? Will I even be able to swim?

Recently, a concerned traveler took to Reddit to ask exactly this, specifically citing a fear of unheated pools. The responses were reassuring but honest, confirming what we at The Cabo Sun tell our readers every year: Cabo in January is paradise, as long as you know what to expect.

The short answer is: No, it is not too cold. In fact, for many, it is the absolute best time of year to visit. But there are a few specific details about pools, packing, and ocean swimming that can make or break your trip.

The Vibe: “Goldilocks” Weather

First, let’s look at the air temperature. January daytime highs consistently hit 75°F to 80°F (24°C – 27°C). It is sunny, dry, and has zero humidity. You will absolutely get a tan. You will wear shorts. You will drink margaritas on the sand.

As we detailed in our guide to Cabo winter weather, this is arguably the most comfortable climate in North America. You can play golf without sweating through your shirt and eat dinner outside without swatting mosquitoes.

The Pool Reality Check

The Reddit user asked if it would be “too cold to use the pool.” The answer is: It depends on the heater.

In January, overnight lows drop to 55°F – 60°F. This cools down unheated bodies of water significantly.

• Unheated Pools: These will feel brisk (approx. 68°F). While refreshing after a hot hike, they aren’t great for all-day lounging.
• Heated Pools: This is the norm for major resorts. Most properties heat their main pools to a comfortable 82°F-84°F, making them perfect for swimming even when the air is crisp in the morning.

Insider Tip: The Reddit user noted their resort said pools are “tempered.” In hotel speak, this usually means “kept comfortably swimmable,” but not “hot bath” warm. It’s usually fine for active swimming, but maybe chilly for long floating with a drink.

The Ocean: Look, Don’t Touch (Much)

The Sea of Cortez is at its coolest in late winter/early spring, hovering around 72°F. Is it swimmable? Yes. Is it warm? No. It’s refreshing. You’ll see plenty of people taking quick dips at Medano Beach, but you won’t see many people lounging in the surf for hours like they do in July.

Why January Still Wins

Despite the “chill,” January is peak season for a reason.

1. Whales: This is the absolute peak of the whale watching season. You can often see humpbacks breaching from your balcony.
2. No Sweat: You can hike, explore downtown San José, or ride ATVs without heat exhaustion.
3. The Vibe: It’s sophisticated snowbird season, not rowdy spring break.

What To Pack (The Strategy)

You need a “mullet” wardrobe: Summer on the bottom, Winter on top.

• Daytime: Swimsuits and cover-ups.
• Evening: You must bring a real jacket or heavy sweater. Dining al fresco at 7 PM in 62-degree breezy weather is chilly. We have a full packing breakdown here.

The Verdict

Is it too cold? No. It is perfect. Just make sure your hotel has a heated pool, bring a hoodie for the evenings, and enjoy the whales. It beats the snow back home every time.
