What is each month like in Bryan?
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 Bryan?

The last spring frost (32°F) comes after February 27 in half of years and the first autumn frost before November 30. Its record high is 112°F (2023) and its record low −3°F (1949), on the National Weather Service's long record for the area (kept since 1888).
