When is the best weather to visit Delhi?
Normal highs sit between 65°F and 85°F in May, June, July, August and September. Of those, September has the fewest days with rain (12).
That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Delhi?
In Delhi, the last spring frost (32°F) comes after May 19 in half of years and after June 3 in one year in ten; the first autumn frost comes before October 1 in half of years and before September 17 in one year in ten.

- May 191 year in 10 after June 3; 9 in 10 after May 1
- First autumn frost, half of years before
- October 11 year in 10 before September 17; 9 in 10 before October 14
NOAA puts the median frost-free season at 132 days, and the season without a hard freeze (28°F) at 158 days.
A hard freeze (28°F) comes after May 5 in half of springs and before October 11 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Delhi in zone 5a in ZIP code 13753, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Delhi's NOAA station is in zone 5b: the coldest night of a typical year reaches −15°F (21 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Has Delhi been warmer than normal lately?
Over 65 complete years from 1925 to 2025, the station's annual mean temperature rose at a fitted 1.5°F per century (+0.09°C per decade). A fitted rate summarizes the whole record; single years swing well above and below it.

Which places near Delhi share this climate record?
2 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
