The year, day by day
Lebanon works both ends of the calendar. Normal highs climb to 91°F by July 24 and hold at or above 90°F on 38 dates, then normal lows drop to freezing or below on 76 dates, bottoming at 27°F around January 18.
When the heat sits
Normal highs reach 90°F from July 8 through August 14, covering 38 dates. The broader mild season, normal highs of 70°F or more, runs April 13 to October 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.
The freezing stretch
The normal low stays at or below 32°F into February 23, then returns to freezing around December 10, covering 76 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 December 23, when 37% of years recorded at least a hundredth of an inch. The driest is September 11 at 24%. Summed across the calendar, that is about 117 wet dates a year.
The widest day
October 18 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Lebanon Stands Nationally

Lebanon spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Lebanon has no dry season to plan around, though it does carry a 42.1°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.6" and October 3.4". The three wettest months together take 29% 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 Lebanon, it arrives in quantity
54.5" of precipitation falls across only about 117 wet days here, averaging 0.47 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 117 a year, 32% of all days
- Average depth per wet day
- 0.47 inches
- Most wet days

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 Lebanon's climate pattern fits together
heating led · wet · mid swing
Lebanon's energy balance leans toward cold weather: 3,802 annual heating degree days against 1,671 for cooling. Its 42.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Lebanon's frost-free season lasts about 205 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Lebanon's middle-range seasonal profile. The measured spread is 42.1°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Lebanon carries 54.5 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Lebanon'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 Lebanon, 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 Lebanon's primary station: LEBANON (USC00405108). 2 NOAA stations are mapped to the Lebanon area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 4741520). Match rule for Lebanon: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Lebanon comes from its primary NOAA station record.
