What is each month like in Sandy Springs?
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.

How much snow, how late a frost, what zone and how much sun in Sandy Springs?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Chamblee (5 miles SE, 1,002 ft). NOAA publishes no snowfall normal for it; the nearest record that has one, Mableton (13 miles SW), gets 1 inches a year. The last spring frost (32°F) comes after March 25 in half of years and the first autumn frost before November 9. Its record high is 105°F (2012) and its record low 5°F (2014) (kept since 1998).
The USDA's 2023 Plant Hardiness Zone Map puts Sandy Springs in zone 8a 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); July is the sunniest month (80%) and February the cloudiest (69%).
Chamblee'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 Sandy Springs; the nearest record's month pages have them.
