The year, day by day
The calendar barely moves in Brunswick: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 43°F near January 16 and 89°F near July 26.
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 43°F around January 16.
Where the wet dates fall
The likeliest wet date is August 18, when 44% of years recorded at least a hundredth of an inch. The driest is April 26 at 21%. Summed across the calendar, that is about 110 wet dates a year.
The widest day
February 12 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Brunswick runs a summer-peaked wet season
37% of Brunswick's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is August at 6.5", on an unusually narrow 28.6°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: August, June, September, taking 38% of the annual total between them.
- Driest month: November at 1.7".
- Winter share: 18% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Brunswick, it arrives in quantity
47.2" of precipitation falls across only about 110 wet days here, averaging 0.43 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 110 a year, 30% of all days
- Average depth per wet day
- 0.43 inches
- Most wet days
- August, about 14
- Fewest wet days
- April, about 7
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 Brunswick's climate pattern fits together
mixed demand · wet · low swing
Water is prominent even though neither heating nor cooling wholly defines the record. Brunswick averages 47.2 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.
Brunswick's 28.6°F seasonal spread is compact even though precipitation is abundant. July and January mark the typical warm and cold ends of the calendar. The annual average is 68°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
Brunswick combines a compact 28.6°F annual temperature range with meaningful demand on both sides of the thermostat: 1,423 heating and 2,464 cooling degree days. The balance matters more here than either annual total in isolation.
The frost-free window extends for about 298 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 Brunswick'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 Brunswick, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
