The freezing stretch

Freezing normal lows persist into February 9, covering 37 dates.

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 July 27, when 39% of years recorded at least a hundredth of an inch. The driest is October 4 at 28%. Summed across the calendar, that is about 124 wet dates a year.

The widest day

April 9 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Suffolk Lake Kilby spreads its precipitation across the year

Neither half of the year dominates here: June through August take 31% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Suffolk Lake Kilby has no dry season to plan around, though it does carry a 38.1°F seasonal spread.

The gap between the wettest and driest month still matters: September averages 5.8" and February 3.0". The three wettest months together take 33% 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 Suffolk Lake Kilby, it arrives in quantity

51.8" of precipitation falls across only about 124 wet days here, averaging 0.42 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 124 a year, 34% of all days
Average depth per wet day
0.42 inches
Most wet days

Fewest 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.

Snow reaches Suffolk Lake Kilby, but rarely amounts to much

The normals record 5.8 inches of snow a year here, most likely in January. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.

A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 3 days a year record any measurable snow at all.

NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile

How Suffolk Lake Kilby's climate pattern fits together

heating led · wet · mid swing

Suffolk Lake Kilby's energy balance leans toward cold weather: 3,465 annual heating degree days against 1,462 for cooling. Its 38.1°F seasonal range still makes the monthly rows more useful than the annual average alone.

Suffolk Lake Kilby's frost-free season lasts about 233 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 Suffolk Lake Kilby's middle-range seasonal profile. The measured spread is 38.1°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, Suffolk Lake Kilby carries 51.8 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 5.8 inches. 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 Suffolk Lake Kilby'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 Suffolk Lake Kilby, 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 Suffolk Lake Kilby's primary station: SUFFOLK LAKE KILBY (USC00448192). 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 Suffolk Lake Kilby; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
