Questions people ask
- Does it rain in Panama in May?
- Yes, often: Panama City’s weather station averages 225 mm (8.9 in) of rain in May, with rain on about 15 days in a typical May (WMO, 1971–2000). NASA POWER’s 2016–2025 average for the area is 283 mm (11.1 in).
- How hot is Panama City in May?
- Panama City’s weather station averages 94°F by day and 70°F at night in May (WMO, 1971–2000). NASA POWER’s ten-year average for the area, which covers land and sea together, is milder: 86°F by day and 80°F at night. For Boquete, NASA POWER’s figures cover an area averaging 688 m up (81°F by day and 71°F at night); the town is at about 1,100 m, so it is cooler than that, especially at night.
- Is May a good month for the Caribbean islands?
- San Blas averages 368 mm (14.5 in) of rain in May and Bocas del Toro 334 mm (13.1 in): “rainy” at both by our bands (dry under 60 mm, rainy over 200 mm). The islands are warm all year: highs around 84°F at San Blas.

Where the numbers come from
- Monthly averages: NASA POWER daily data for 2016–2025 (fetched Tue, Nov 10, 2026), averaged by us: the average day’s high and low, the month’s total rain, humidity and cloud. Each figure covers a grid square of roughly 55 by 70 km of land and sea, so Panama City’s afternoons come out about 4.2°C cooler than at the city’s own weather station.
- Panama City’s figures lead with its weather station normals (1971–2000): World Meteorological Organization, from Panama’s weather service (IMHPA). A rain day there is a day with at least 0.1 mm.
- Left out on purpose: NASA POWER’s rain-day counts, because its model drizzles on most days and counts about 27 “rain days” in a wet-season month where Panama City’s station records 14 to 20; and its UV index, which is a 24-hour average far below the midday peak you feel. Rain days on these pages are the station’s, for Panama City only.
- Our rain bands: “dry” is under 60 mm in the month, “rainy” over 200 mm, and “some rain” in between.
- Forecasts: Weather data: MET Norway (CC BY 4.0), refreshed at most every half hour.
- Sea temperature: NOAA OISST v2.1 (NOAA NCEI’s daily 0.25° sea-surface temperature analysis, Version v02r01), 2016–2025, averaged by us for one grid cell per sea: Panama Bay (Pacific) (8.625°N, 79.375°W, the open bay south of Panama City); Guna Yala coast (Caribbean) (9.625°N, 78.875°W, off the San Blas islands); Off Bocas del Toro (Caribbean) (9.625°N, 82.125°W, just north of the Bocas del Toro islands).
