Panama has a tropical maritime climate with a hot, humid, cloudy prolonged rainy season (May to January) and a short dry season (January to May).
It is completely outside the hurricane belt and experiences few if any natural disasters. Most of Panama has two seasons: wet (“winter”) and dry (“summer”).
Summer is roughly from December to April. In May, the rains start gradually with frequent showers (most lasting no more than an hour or two). The wet season generally culminates in November with major downpours.
Though some afternoons can be very muggy, hours or days of continuous rain are very rare…especially in Panama City and the Pacific coast area known as the Arco Seco, or dry arc.
Bocas del Toro and other locations on Panama’s less-developed Caribbean Coast receive twice as much rain as the Pacific Coast.
Although the official rainy season is December through April, the rest of the year may bring frequent rain, too.
Seek out the highlands if warm, steamy weather bothers you. They have a more tropical climate, so cool, misty showers are common during the rainy season. After all, you can’t have rainforests and cloud forests without rain and clouds.
The wetness tends to bother people less in the mountains, even in Boquete, which gets its fair share of downpours from August to November. That’s probably because without the sea-level heat, the humidity is less noticeable.
Many say Panama’s climate is better for their skin, keeping it moisturized and smooth-looking, rather than dry and papery.
