Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Frost Dates and Growing Season

87 years with a frost

Across 87 years with a frost, the median last spring frost at Hannibal Wtr Wks falls on 13 April and the median first autumn frost on 25 October, which leaves a median of 192 days between them.

In 1996 to 2025 the median growing season was 202 days. That is 12 days more than in 1934 to 1964.

Fitted over all years, the growing season changes by +1.7 days per decade at this station.

Growing days192 days190 days202 days12 days more+1.7 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.

Rainfall Return Levels

92 years, 1934 to 2025

A day with at least 67.9 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 149.7 mm (5.9 in) of rain is expected about once in 100 years.

50 years136.6 mm (5.4 in)
100 years149.7 mm (5.9 in)Longer than the 92 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 92 years of values from 1934 to 2025.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 150.4 mm (5.9 in) in 1949; 128.8 mm (5.1 in) in 2014; 124.2 mm (4.9 in) in 2003.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Hannibal Wtr Wks had a mean temperature of 12.2 C (54.0 F) and 1,033.0 mm (40.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Vincennes 4 E (United States, 356 km away), Alton - Melvin Price L&D (United States, 142 km away) and Palestine (United States, 333 km away).

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
