A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Toledo varies throughout the year.
The wetter season lasts 6.4 months, from March 24 to October 4, with a greater than 26% chance of a given day being a wet day. The chance of a wet day peaks at 36% on June 7.
The drier season lasts 5.6 months, from October 4 to March 24. The smallest chance of a wet day is 16% on January 31.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 36% on June 7.
Daily Chance of Precipitation
To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Toledo experiences significant seasonal variation in monthly rainfall.
Rain falls throughout the year in Toledo. The most rain falls during the 31 days centered around June 2, with an average total accumulation of 3.2 inches.
The least rain falls around January 28, with an average total accumulation of 0.9 inches.
Average Monthly Rainfall
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.
As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Toledo experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 4.3 months, from November 26 to April 5, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around February 14, with an average total liquid-equivalent accumulation of 0.4 inches.
The snowless period of the year lasts for 7.7 months, from April 5 to November 26. The least snow falls around July 20, with an average total liquid-equivalent accumulation of 0.0 inches.

Sunrise & Sunset with Twilight and Daylight Saving Time
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
Toledo experiences significant seasonal variation in the perceived humidity.
The muggier period of the year lasts for 3.7 months, from May 31 to September 20, during which time the comfort level is muggy, oppressive, or miserable at least 10% of the time. The muggiest day of the year is July 28, with muggy conditions 40% of the time.
The least muggy day of the year is December 9, when muggy conditions are essentially unheard of.

This report illustrates the typical weather in Toledo, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Toledo.
For each station, the records are corrected for the elevation difference between that station and Toledo according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Toledo is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Toledo and a given station.
The stations contributing to this reconstruction are: Toledo Suburban Airport (45%, 12 kilometers, northwest); Toledo Executive Airport (38%, 13 kilometers, southeast); and Toledo Express Airport (17%, 23 kilometers, west).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
