It’s not exactly cold in Costa Rica but it’s never as deathly hot as the summer heat tsunami hitting much of the United States. Honestly, if you flew from that “heat dome” to the tropical latitudes of Costa Rica, you wouldn’t feel as roasted no matter which part of the country you visited. Up in Guanacaste, temps would get up into the 90s, but it wouldn’t be as humid and you might see a large-eyed, Double-striped Thick-Knee or get a chance to study Nutting’s Flycatchers.
Further south on the Pacific coast, it’s definitely hot and humid but the mercury still doesn’t rise more than 92 degrees. Cloudy weather also tends to make it a bit cooler and you will note nicer temps inside heavily shaded primary forest as well. Over in the Caribbean lowlands, the birding takes place in humid, 80 something degree weather but that’s never as bad as a the 100 degree, outdoor humid sauna taking place in the USA.
On the south Pacific slope, you could run into Fiery-billed Aracaris (above),and then watch their Caribbean slope counterparts Collared Aracari (below) on the other side of the mountains.
If your desire to escape the heat is enough to forgo birding in the lowlands altogether, then head up into the subtropical zone where temperatures are a pleasant 70 something degrees. Higher still, you can watch the Talamancan endemics and pretend that its Autumn with 65 degree days and 50 degree nights.
Regionally endemic Prong-billed Barbets are a fairly common sight when birding Costa Rica cloud forests.
Volcano Hummingbirds are abundant in high elevation habitats.
Weather in the Central Valley is s bit like that of cloud forest but drier. For example, as I write this post, it’s about 78 degrees outside with moderate humidity. Yes, quite close to most people’s idea of “perfect”. Despite it being the rainy season, we are also getting beautiful, sunny weather so don’t think for a second that you can only visit during the dry season, or that Costa Rica is too hot any time of the year. The outdoors are pretty much like this year round with varying amounts of rain. Oh, and the birding is pretty good too! I’m hoping to get out this weekend to look for bellbirds or fruiting trees that may hold uncommon post-breeding frugivores. I might also head over to Cachi Lake and try for my long-awaited Masked Duck. Whatever I end up doing, the birding is guaranteed to be exciting.
