Checking the past data from the Palmira Arriba Station over a span of 19 years, the average rainfall for the months of November is 11.56 inches.  The range is a low of 1.50 inches to a high of 41.16 inches. This month's 3.15 inches is -0.84 standard deviations below the mean compared to the means for November.  So we had less rain in November than we normally expect but only about one standard deviation below the normal statistical range. November is usually a transition month when we move from the rainy season into the beginning of the Dry Season.  In the 19 years of data collection we have had 12 Novembers with this lower amount of rain.  So this decrease of rain in November 2025 is not all that unusual.  We are gradually transitioning into the Dry Season.

The latest ENSO Cycle Report is saying that "La Niña is present. Equatorial sea surface temperatures (SSTs) are below average across the central and east-central Pacific Ocean. Atmospheric anomalies over the tropical Pacific Ocean are consistent with La Niña. La Niña is favored to continue into the Northern Hemisphere winter, with a transition to ENSO-neutral most likely in January-March 2026 (61% chance)."

Here is a link to a source to better understand El Niño in case you need some help interpreting what this all means. Give this a read and you will learn a lot about this important weather phenomenon that affects global weather. It has more effect upon the Northern Latitudes than it has upon us here in the tropics. 

The IRI (International Research Institute for Climate and Society) (select South America from the Region menu) is predicting above normal precipitation in Panama with eastern parts having a 70% probability of precipitation and western parts 50% probability during the months of December - January - February of 2026 (Blue and Green areas).

IMHPA (Instituto de Meteorología e Hidrología de Panamá) documents section predicts that during December  "...Rainfall values ​​are expected to be above normal in the western Caribbean region: eastern Bocas del Toro province, northern Ngäbe Buglé Comarca, northern Veraguas, the lower coast of Colón, and northern Coclé. For the rest of the country, rainfall is expected to be within the normal range for the month, with a decrease in rainfall in some areas of Chiriquí, Veraguas, Panama Oeste, and the Panama Canal."  You can read their entire report and check out the details in the "documents" section at this link.
