Climate of Panama Panama has a tropical climate with little seasonal variations. Temperatures are uniformly high - as is the humidity. There are only two seasons: a dry season and the rainy season. The dry season starts in mid-December and continues through to the end of April. It is typified by clear skies and often strong breezes, with very little rain and therefore relatively less humidity. On a typical dry season day in Panama City, the early morning minimum may be 24C and the afternoon maximum 32C. Temperatures rarely rise above 32/33C.
The Panamanians call the dry season summer (verano) and the rainy season winter (invierno). The latter is a misnomer, because morning low temperatures during “winter” are still above 20C, with the exception of the mountain areas, where temperatures may drop to as low as 17C at the height of the rainy season during October and November.
The other high rainfall month is May, with precipitation from June to September less intense. Statistically a typical Panamanian rain storm lasts an average of twelve minutes, marked by heavy downpours and often thunder and lightning.

It is not persistent frontal rain like in the Western Cape, but short, sharp cloudbursts often leading to localized flooding. The mornings in the rainy season are beautiful and clear, with the clouds accumulating around lunchtime and the rain pouring down briefly sometime between one and four – then it clears up to provide spectacular sunsets. During the rainy season there is little or no wind (the typical tropical doldrums) and humidity is very high.
