A look at my favorite countries that are warm in December

I’m often asked about good travel destinations when families are looking to escape the cold. Now, since I’m from San Diego, the winter months aren’t nearly as miserable for me as they might be for others. For most people, when December rolls around, it means cozy sweaters, shorter days, and dreaming about sunshine instead of snow.

But that’s why December is such a great month to travel. While some families are bundling up for winter activities, you could be packing swimsuits and flip-flops and heading somewhere warm. And, if you’ve been searching for countries that are warm in December, you’re in luck.

There are plenty of amazing destinations around the world where you can trade icy sidewalks for sandy beaches, palm trees, and outdoor adventures—all while schools are on break.

To make things easy, I’m focusing on some of the best family-friendly warm-weather countries that are especially great to visit in December.

And, if it’s a snowy winter retreat you were hoping to plan, make sure to check out my favorite snow-filled winter destinations.
