About this data

All figures are 25-year averages (January 2001 – December 2025) from the NASA POWER project. Temperature, humidity, wind and precipitation come from the MERRA-2 reanalysis (precipitation is the bias-corrected MERRA-2 product), cloud and solar values from CERES satellite data. They describe a grid cell of roughly 50–70 km, not a single weather station, so they can differ from airport records — most of all on coasts, in mountains and for rainfall. Average highs and lows are the monthly mean temperature plus/minus half of the average daily temperature range. Counts of rainy days are not part of this dataset.

The grid cell’s average elevation is 75 m, while Chongdan-up lies at about 21 m. Temperatures on this page were therefore adjusted by +0.4 °C0.6 °F using the standard lapse rate of 6.5 °C per 1,000 m.
