What is each month like in Warwick?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

What do the station records around Warwick say?
Each row is a NOAA station's own 1991-2020 normals, with the snow and frost dates the grid does not give. A record downhill or nearer the coast than the city can run warmer, one uphill cooler: compare the elevations.

How much snow, how late a frost, what zone and how much sun in Warwick?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Providence (1 miles NW, 60 ft). It gets 37 inches of snow in a normal year. The last spring frost (32°F) comes after April 11 in half of years and the first autumn frost before October 30. Its record high is 104°F (1975) and its record low −17°F (1934), on the National Weather Service's long record for the area (kept since 1904).
The USDA's 2023 Plant Hardiness Zone Map puts Warwick in zone 7a across its 4 ZIP code areas.
Over a year 75% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (4.0 kWh per square metre a day, NASA POWER 2001-2020); August is the sunniest month (81%) and December the cloudiest (67%).
Providence's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for Warwick; the nearest record's month pages have them.
