The year, day by day
The calendar barely moves in Concord Wwtp: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 41°F near December 18 and 89°F near July 11.
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 41°F around December 18.
Where the wet dates fall
The likeliest wet date is February 14, when 34% of years recorded at least a hundredth of an inch. The driest is July 27 at 0%. Summed across the calendar, that is about 57 wet dates a year.
The widest day
July 9 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Concord Wwtp's wet season runs through the cold months
December, January and February carry 60% of the year's precipitation here, while June through August contribute 1%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows an unusually narrow 23.6°F seasonal spread.
- Wettest month
- February, 3.6"
- Driest month
- July, 0.0"
- Wettest three months
- February, December, January (60% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
How Concord Wwtp's precipitation splits across the calendar
About 56 days a year record measurable precipitation here, carrying 17.7" between them, or roughly 0.31 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Concord Wwtp's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Concord Wwtp's climate pattern fits together
mixed demand · dry · low swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 17.7 inches annually, within PlainClimate's dry band. Recorded annual snowfall is negligible. The monthly distribution matters because the total alone does not reveal the timing.
The calendar stays thermally compact and dry. August and December mark the typical warm and cold ends of the calendar, only 23.6°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 62°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Concord Wwtp combines a compact 23.6°F annual temperature range with meaningful demand on both sides of the thermostat: 2,029 heating and 1,084 cooling degree days. The balance matters more here than either annual total in isolation.
Concord Wwtp has a long frost-free window of roughly 346 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
These labels group NOAA 1991-2020 normals from Concord Wwtp's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Concord Wwtp, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

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 Concord Wwtp; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
