The year, day by day
MD Sci Ctr Baltimore works both ends of the calendar. Normal highs climb to 91°F by July 9 and hold at or above 90°F on 20 dates, then normal lows drop to freezing or below on 51 dates, bottoming at 30°F around January 21.
When the heat sits
Normal highs reach 90°F from July 4 through July 23, covering 20 dates. The broader mild season, normal highs of 70°F or more, runs April 25 to October 12.
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.
The freezing stretch
The normal low stays at or below 32°F into February 16, then returns to freezing around December 28, covering 51 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.
Where the wet dates fall
The likeliest wet date is April 7, when 37% of years recorded at least a hundredth of an inch. The driest is October 31 at 26%. Summed across the calendar, that is about 119 wet dates a year.
The widest day
April 18 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

MD Sci Ctr Baltimore spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. MD Sci Ctr Baltimore has no dry season to plan around, though it does carry a 44.6°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 4.7" and February 2.8". The three wettest months together take 31% 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 MD Sci Ctr Baltimore, it arrives in quantity
43.7" of precipitation falls across only about 119 wet days here, averaging 0.37 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 119 a year, 33% of all days
- Average depth per wet day

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 MD Sci Ctr Baltimore's climate pattern fits together
heating led · moderate · mid swing
MD Sci Ctr Baltimore's energy balance leans toward cold weather: 3,858 annual heating degree days against 1,749 for cooling. Its 44.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
The frost-free window extends for about 242 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.
July and January mark the typical warm and cold ends of the calendar in MD Sci Ctr Baltimore's middle-range seasonal profile. The measured spread is 44.6°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
MD Sci Ctr Baltimore's 43.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from MD Sci Ctr Baltimore'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 MD Sci Ctr Baltimore, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from MD Sci Ctr Baltimore's primary station: MD SCI CTR BALTIMORE (USW00093784). 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 MD Sci Ctr Baltimore; 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 MD Sci Ctr Baltimore comes from its primary NOAA station record.
