What the New York City climate table shows
Values are multi-decadal climatological averages for the 40.7143, -74.006 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
How much rain is 4.28 mm/day in a month?
Rain is recorded as a daily mean, so 4.28 mm/day is roughly 130 mm across a 30-day month.
