Beachgoers at Playa Guiones in Nosara, Guanacaste received an unexpected surprise Monday as two large whales breached not far offshore.
It was an experience unlike any other.

September is probably the best month to see majestic humpback whales with their babies in the shallow waters of Bahía Ballena off the Pacific coast town of Uvita.
Biologists saw humpback whales that usually migrate from Antarctica to the equator to calve are now also continuing north beyond the equator, as far as Costa Rica -- a behavior never seen before. The increasingly long journeys, a result of climate change, are taking a toll on the animals' health, scientists say.
