While you plan Baja travel for any time of year, Baja cruises in the Sea of Cortez primarily operate in the months of November through April, taking advantage of pleasant weather and sailing conditions. The hot, sunny and dry desert climate offers the perfect getaway from winter in North America. We offer various options to explore Baja, by land and sea, with our expedition cruise options including small ships of 8 to 100 guests. Here’s a look at what’s happening in Baja by month, so you can plan the best Baja travel time for your interests.

January, February & March in Baja

The midwinter months of January through March are the most popular time to travel in Baja due to prime weather and wildlife. Cooler ocean currents bring oxygen and nutrient-rich water to the surface where they mix with abundant sunlight resulting in a bloom of food for marine animals. Small plankton are the foundation of a thriving food chain that lures migratory whales, other marine mammals and birdlife to Baja and the Sea of Cortez. Many of these plankton are also photo sensitive and result in astounding light shows in the water. Highlights during this time are:

  • Whales begin to arrive in December and remain through April, but the winter months of January through March are the best time to see gray whales in the mating and breeding lagoons along the Pacific coast.
  • Migratory humpback whales and whale sharks are also at peak numbers in the Sea of Cortez during this time.
  • Tropical storms, known as chubascos, can bring high winds and rough seas, although these are usually short lived.
  • Water temperatures average 70 degrees Fahrenheit, with air temperatures in the 70s.

July, August & September in Baja

Summer is the hottest time of year, and in Baja it can be extreme. Because of this there are few, if any, small ship cruises operating July through September. Most small ships relocate north to Alaska or south to Costa Rica and Panama. Land-based tours such as the Baja Intimate Insider, in the Southern Peninsula offer some respite from the heat, especially on the Pacific coast.

  • This is the best time of year to view blue and fin whales with the season continuing through October.
  • This is the most common time to see sperm whales in the Sea of Cortez.
  • Elephant seals can be found in select regions along the Pacific coast. They come ashore to breed, give birth and molt. 
  • Summer months are a good time to view chackwalla, iguana, lizards and sea turtles.
  • The best time to spot blue-footed boobies.
  • Water temperatures reach into the 80s, with air temperatures in the 90s.

October, November & December in Baja

Fall in Baja and the Sea of Cortez marks a return to pleasant temperatures and the beginning of the small ship cruise season. This is a great time to travel before high-season crowds arrive during the December holidays.

  • Gray and humpback whale season begins with most whales arriving by late December.
  • There are some chances to see blue, fin and sperm whales with sightings decreasing as the season progresses.
  • Sea turtles and whale sharks, the largest fish in the world, become active.
