A year of rain and warmth.
Compare the shape of a typical year in two districts. Each measure comes from a different source and period.
TWO DISTRICTS / ONE MEASURE
Look month by month.
The chart compares a historical normal or climatology, not year-by-year weather. Choose a measure and two districts.
IMD monthly rainfall normals, in millimetres, based on available historical station records during the nominal 1951–2000 period. Not every station has a complete series; the publication’s district geography is not certified as current.

NASA POWER / ANNUAL POINT ESTIMATES
Climate, year by year.
Compare the two selected districts from 2001 to 2025. These are coarse MERRA-2 estimates at one representative point, not district-wide averages or direct station observations. The vertical scale adjusts to the selected series.
Annual mean air temperature at 2 metres.
On a narrow screen, scroll the chart sideways; the table below contains every value.
