What is each month like in Bossier City?
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.

The last spring frost (32°F) comes after March 6 in half of years and the first autumn frost before November 18. Its record high is 108°F (1998) and its record low 3°F (1989) (kept since 1969).
The USDA's 2023 Plant Hardiness Zone Map puts Bossier City in zone 8b across its 3 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 (4.6 kWh per square metre a day, NASA POWER 2001-2020); August is the sunniest month (84%) and February the cloudiest (64%).
Red River Research Station'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 Bossier City; the nearest record's month pages have them.
