If you head to the ocean in the tropics you will find warm water. How warm? Generally, pretty much like bath water. I have talked so much about cooler weather (in the mountains) so people were getting concerned that there was no warm place to go.
Yes, that’s another warm beach on the coast of Costa Rica. Besides the temperature, have you noticed another big difference? I grew up in Southern California. Sometimes the beaches were so crowded that you might just see blankets with people on them rather than any sand. When I have been to a beach in Costa Rica, Nicaragua or Guatemala they may have some people on them but being crowded has never been an issue.
And, then, you can wait for sunset. You won’t be disappointed.
