The Weather
Without question the most informative site we have discovered about the weather in Boquete is Lloyd's Cripe's boqueteweather.com. No doubt he spent hundreds of hours researching and developing the content for this site, and we heartedly commend him for his amazing  efforts.

We were fascinated by his explanation of all the climatic conditions affecting the weather in and around Boquete and we encourage you to visit his most informative website for more detailed information

Here is just a sampling of the facts on his site....

Bajareque?

During the dry season, the northern winds can carry some moisture over the mountain range from the Caribbean Sea...Since the Boquete District is on the leeward side of the mountains relative to the Caribbean cloud systems, the moisture that gets pushed over from the Caribbean side usually comes in the form of a mist or light rain that is locally called the “bajareque.” It is a fine but very wet mist.

Winds? 
At times there are winds from the north. At other times there are winds from the south. While at other times, there are no winds. Typically, strong northerly winds occur during the dry season.

During the months of January, February and March, we experience the strongest northeastern winds. Boquete can be a very windy place during these months. 

Know what Inter-Tropical Convergence Zone (ITCZ)means?

We didn't either. Lloyd provides a detailed explanation as to why we have "wet" and "dry" seasons in Panama. Fascinating stuff!

In Panama, the ITCZ moves south of us from December to April and moves upon us from May to November. As it leaves and moves more south of us, we have little or no rain – the Dry Season. When it moves more northerly and is closer to us or over us, we have rain, usually in the form of thunderstorms – the Wet Season.

A fascinating story....

In 1911, the naturalist Henry Pittier explored Chiriqui as well as other parts of Panama and wrote about the adventure in a 1912 National Geographic article. He rode horseback from David to Boquete. His description of the 3 day 25 mile journey is very interesting. He commented:

"Going north in the direction of the Chriqui Peak, one is soon struck by the peculiar range of low hills running, as it seems between the plains and the mountains and parallel to the sea-coast. The road winds between these and , mostly following the Dolega River, ascends gradually toward El Boquete. The general incline is so insensible that one travels nearly 25 miles before reaching the foot of the volcano, at an altitude of about 3000 feet. The ride is mainly across savannas or through what ecologists call a park like landscape.

During the dry season the long stretches, bare of arboreous vegetation, are constantly swept by the north trade wind, which attains its major intensity between 9 o'clock a. m. and 3 o'clock p. m., and is often of such violence that even the horses find it difficult to stand and to proceed on their way. Every detail of the surrounding landscape bears the impress of the wind. In the most exposed places the surface of the soil is submitted to an active aerial erosion, the minute particles of the ground being whisked away the moment they become loose." -page 631
