Panama Weather in May: Rain, Temperatures

Panama weather in May is hot and wet, which makes this month less appealing for cruise and resort visitors.

Panama has three major vacation destinations: the Colon cruise port on the Caribbean coast, Bocas del Toro on the Caribbean coast and the Panama City cruise port on the Pacific coast.

Colon and Panama City share similar weather because they are only 46 miles away from each other despite being on different coasts.

They are both hotter and drier than Bocas del Toro, which lies farther north.

Panama Temperatures in May

The average high temperature in May for Colon and Panama City is 94 degrees Fahrenheit or about 34 Celsius, according to the country’s meteorological service. Although the average sounds hot, the area has daytime temperatures of at least 90 Fahrenheit every month of the year.

The average low temperature is 70 Fahrenheit or 21 Celsius. Panama is unusual in the Caribbean for such extremes between the daytime highs and nighttime lows. The nighttime temperatures are low enough that water temperatures may feel chilly at times in the early mornings.

Panama Rainy Season in May

May is the start of the Panama rainy season. Colon and Panama City average about nine inches of rain during the month. The average for Bocas del Toro is seven.

These rainfall averages are a big jump from April for Colon and Panama City when the average is three inches. Bocas del Toro, which has frequent rain throughout the year, has an average of 15 inches in April by comparison.

Regardless of the destination, the three major tourism destinations in Panama have hot temperatures and the risk of heavy rain in May. Anyone planning to visit should consider going from December through April to Colon and Panama City during their dry seasons.
