What is each month like in Hoover?
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 Hoover 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 Hoover?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Helena (7 miles S, 480 ft). NOAA publishes no snowfall normal for it; the nearest record that has one, Bessemer (12 miles W), gets 1 inches a year. The last spring frost (32°F) comes after March 19 in half of years and the first autumn frost before November 8.
The USDA's 2023 Plant Hardiness Zone Map puts Hoover in zones 8a to 8b across its 4 ZIP code areas.
Over a year 77% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (4.5 kWh per square metre a day, NASA POWER 2001-2020); September is the sunniest month (80%) and February the cloudiest (67%).
Helena'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 Hoover; the nearest record's month pages have them.
