The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 22, short of 90°F on every date, while 161 dates carry a normal low at or below freezing, the coldest 14°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into March 31, then returns to freezing around October 23, covering 161 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
July 12 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Bellevue Stands Nationally
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Bellevue earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Bellevue spreads its precipitation across the year
Neither half of the year dominates here: June through August take 15% of the annual total and December through February 34%, with neither reaching the 35% that would mark a distinct wet season. Bellevue has no dry season to plan around, though it does carry a wide 45.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: December averages 2.4" and July 0.6". The three wettest months together take 37% 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.

Data-derived climate profile
How Bellevue's climate pattern fits together
heating led · dry · mid swing
Bellevue's energy balance leans toward cold weather: 7,012 annual heating degree days against 434 for cooling. Its 45.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 142 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Bellevue's middle-range seasonal profile. The measured spread is 45.4°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Bellevue's cold-season load does not imply a wet climate. Annual precipitation is 17.5 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Bellevue'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 Bellevue, not an official NOAA class or a year-ahead forecast.
