Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Panamá varies significantly throughout the year.

The wetter season lasts 7.5 months, from April 27 to December 11, with a greater than 25% chance of a given day being a wet day. The chance of a wet day peaks at 46% on November 8.

The drier season lasts 4.5 months, from December 11 to April 27. The smallest chance of a wet day is 3% on January 31.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 46% on November 8.

Daily Chance of Precipitation

The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day).

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Panamá experiences very significant seasonal variation in monthly rainfall.

The rainy period of the year lasts for 10.0 months, from March 19 to January 18, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around October 31, with an average total accumulation of 7.7 inches.

The rainless period of the year lasts for 2.0 months, from January 18 to March 19. The least rain falls around February 26, with and average total accumulation of 0.2 inches.

Average Monthly Rainfall

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Humidity

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The perceived humidity level in Panamá, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, staying within 4% of 96% throughout.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Panamá experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 4.7 months, from December 11 to May 2, with average wind speeds of more than 5.5 miles per hour. The windiest day of the year is February 26, with an average hourly wind speed of 7.9 miles per hour.

The calmer time of year lasts for 7.3 months, from May 2 to December 11. The calmest day of the year is September 16, with an average hourly wind speed of 3.2 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Panamá varies throughout the year.

The wind is most often from the south for 3.9 weeks, from September 24 to October 21, with a peak percentage of 40% on October 7. The wind is most often from the north for 11 months, from October 21 to September 24, with a peak percentage of 100% on February 3.

The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Water Temperature

Panamá is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average water temperature experiences some seasonal variation over the course of the year.

The time of year with warmer water lasts for 5.8 months, from May 10 to November 5, with an average temperature above 82°F. The day of the year with the warmest water is June 13, with an average temperature of 84°F.

The time of year with cooler water lasts for 2.2 months, from January 31 to April 5, with an average temperature below 79°F. The day of the year with the coolest water is March 5, with an average temperature of 78°F.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences significant seasonal variation over the course of the year.

The brighter period of the year lasts for 2.8 months, from January 23 to April 17, with an average daily incident shortwave energy per square meter above 5.9 kWh. The brightest day of the year is March 20, with an average of 6.7 kWh.

The darker period of the year lasts for 5.5 months, from May 21 to November 7, with an average daily incident shortwave energy per square meter below 3.8 kWh. The darkest day of the year is July 25, with an average of 3.0 kWh.

Data Sources

This report illustrates the typical weather in Panamá, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There is only a single weather station, Tocumen International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Panamá.

At a distance of 17 kilometers from Panamá, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

The station records are corrected for the elevation difference between the station and Panamá according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
