The year, day by day
The year in Bay City Wtr Wks runs from a mild 42°F around January 8 to 92°F at the peak near August 6, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 3 through September 3, covering 63 dates. The broader mild season, normal highs of 70°F or more, runs March 5 to November 23.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 42°F around January 8.
Where the wet dates fall
The likeliest wet date is September 10, when 33% of years recorded at least a hundredth of an inch. The driest is April 30 at 18%. Summed across the calendar, that is about 96 wet dates a year.
The widest day
October 24 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Where Bay City Wtr Wks Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 63 days a year, more than four out of five ranked stations record.
Days and nights track unusually close together; the widest normal swing, about 21°F, is narrower than most stations record.
Bay City Wtr Wks earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Bay City Wtr Wks spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Bay City Wtr Wks has no dry season to plan around, though it does carry an unusually narrow 29.1°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 5.8" and February 2.5". The three wettest months together take 33% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Bay City Wtr Wks, it arrives in quantity
49.1" of precipitation falls across only about 96 wet days here, averaging 0.51 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 96 a year, 26% of all days
- Average depth per wet day
- 0.51 inches
- Most wet days
- January, about 10
- Fewest wet days
- April, about 6
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Bay City Wtr Wks's climate pattern fits together
cooling led · wet · low swing
Warm-season load persists through a relatively even calendar in Bay City Wtr Wks. Cooling totals 2,733 degree days, more than double the 1,326 heating measure, and the 29.1°F seasonal range is compact rather than sharply divided.
Warm-season demand is paired with a wet annual normal: 49.1 inches of precipitation at Bay City Wtr Wks. Snowfall is not added to the interpretation because its annual value is missing. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
Bay City Wtr Wks's 29.1°F seasonal spread is compact even though precipitation is abundant. August and January mark the typical warm and cold ends of the calendar. The annual average is 69°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
The frost-free window extends for about 286 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
These labels group NOAA 1991-2020 normals from Bay City Wtr Wks's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Bay City Wtr Wks that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Bay City Wtr Wks's primary station: BAY CITY WTR WKS (USC00410569). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Bay City Wtr Wks; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Bay City Wtr Wks comes from its primary NOAA station record.
