The fitted trend in annual mean temperature here over 1900 to 2024 is 0.02 C (-0.05 to 0.09) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.04 F (-0.09 to 0.16) per decade. The slope is a straight line fitted to 87 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.02 C (-0.05 to 0.09) per decade | 0.04 F (-0.09 to 0.16) per decade | 1900 to 2024 | 87 | Not clearly different from zero |
| Mean daily maximum | -0.07 C (-0.16 to 0.02) per decade | -0.13 F (-0.29 to 0.03) per decade | 1900 to 2024 | 87 | Not clearly different from zero |
| Mean daily minimum | 0.1 C (0.1 to 0.2) per decade | 0.2 F (0.1 to 0.3) per decade | 1900 to 2024 | 87 | Rise |
A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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 frostAcross 87 years with a frost, the median last spring frost at Ipswich falls on 15 May and the median first autumn frost on 23 September, which leaves a median of 133 days between them.
In 1993 to 2024 the median growing season was 145 days. That is 20 days more than in 1900 to 1963.
Fitted over all years, the growing season changes by +2.6 days per decade at this station.
| Measure | Median, all years | Earliest period (1900 to 1963) | Recent period (1993 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 15 May | 21 May | 12 May | 9 days earlier | -1.4 days per decade |
| First autumn frost | 23 September | 20 September | 1 October | 11 days later | +1.2 days per decade |
| Growing days | 133 days | 125 days | 145 days | 20 days more | +2.6 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
106 years, 1898 to 2024A day with at least 43.7 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 124.9 mm (4.9 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 43.7 mm (1.7 in) | |
| 5 years | 60.6 mm (2.4 in) | |
| 10 years | 73.5 mm (2.9 in) | |
| 25 years | 92.1 mm (3.6 in) | |
| 50 years | 107.7 mm (4.2 in) | |
| 100 years | 124.9 mm (4.9 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 106 years of values from 1898 to 2024.
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: 152.4 mm (6.0 in) in 1931; 127.5 mm (5.0 in) in 1994; 125.7 mm (4.9 in) in 1899.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2010 to 2024 against 1961 to 1990Over 2010 to 2024, Ipswich had a mean temperature of 6.6 C (43.9 F) and 492.4 mm (19.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Flandreau (United States, 247 km away), Tyler (United States, 264 km away) and Milbank 4 NW (United States, 186 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Flandreau | United States | 247 km (153 mi) | 6.5 C (43.6 F) | 547.9 mm (21.6 in) | 0.79 |
| Tyler | United States | 264 km (164 mi) | 6.5 C (43.8 F) | 614.0 mm (24.2 in) | 0.85 |
| Milbank 4 NW | United States | 186 km (116 mi) | 6.6 C (43.9 F) | 520.7 mm (20.5 in) | 0.94 |
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.
