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
71 years with a frostAcross 71 years with a frost, the median last spring frost at Henderson falls on 13 March and the median first autumn frost on 13 November, which leaves a median of 244 days between them.
In 1985 to 2023 the median growing season was 245 days. That is 4 days more than in 1943 to 1973.
Fitted over all years, the growing season changes by -0.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1943 to 1973) | Recent period (1985 to 2023) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 13 March | 14 March | 13 March | 1 day earlier | +0.1 days per decade |
| First autumn frost | 13 November | 11 November | 13 November | 2 days later | -0.1 days per decade |
| Growing days | 244 days | 241 days | 245 days | 4 days more | -0.1 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
111 years, 1909 to 2023A day with at least 85.3 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 247.6 mm (9.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 85.3 mm (3.4 in) | |
| 5 years | 117.3 mm (4.6 in) | |
| 10 years | 142.4 mm (5.6 in) | |
| 25 years | 179.5 mm (7.1 in) | |
| 50 years | 211.5 mm (8.3 in) | |
| 100 years | 247.6 mm (9.7 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 111 years of values from 1909 to 2023.
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: 280.7 mm (11.1 in) in 1989; 257.0 mm (10.1 in) in 1959; 206.8 mm (8.1 in) in 2013.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2006 to 2023 against 1961 to 1990Over 2006 to 2023, Henderson had a mean temperature of 18.9 C (66.0 F) and 1,190.1 mm (46.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Livingston 2 NNE (United States, 161 km away), Groveton (United States, 115 km away) and Coldspring 5 SSW (United States, 186 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Livingston 2 NNE | United States | 161 km (100 mi) | 18.8 C (65.8 F) | 1,231.9 mm (48.5 in) | 0.52 |
| Groveton | United States | 115 km (71 mi) | 18.9 C (66.1 F) | 1,211.8 mm (47.7 in) | 0.56 |
| Coldspring 5 SSW | United States | 186 km (116 mi) | 18.8 C (65.8 F) | 1,234.5 mm (48.6 in) | 0.64 |
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.
