The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 7, short of 90°F on every date, while 156 dates carry a normal low at or below freezing, the coldest 12°F near February 1.
The freezing stretch
The normal low stays at or below 32°F into April 12, then returns to freezing around November 9, covering 156 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
April 28 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Data-derived climate profile
How Sandusky's climate pattern fits together
heating led · mid swing
Sandusky's energy balance leans toward cold weather: 7,227 annual heating degree days against 488 for cooling. Its 48.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Sandusky's frost-free season lasts about 167 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Sandusky's middle-range seasonal profile. The measured spread is 48.6°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Sandusky's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Sandusky's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Sandusky, not an official NOAA class or a year-ahead forecast.
