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
63 years with a frostAcross 63 years with a frost, the median last spring frost at Grand Haven Fire Dept falls on 30 April and the median first autumn frost on 17 October, which leaves a median of 167 days between them.
In 1966 to 2000 the median growing season was 175 days. That is 12 days more than in 1904 to 1961.
Fitted over all years, the growing season changes by +3.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1904 to 1961) | Recent period (1966 to 2000) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 30 April | 3 May | 1 May | 2 days earlier | -1.6 days per decade |
| First autumn frost | 17 October | 12 October | 22 October | 10 days later | +1.6 days per decade |
| Growing days | 167 days | 163 days | 175 days | 12 days more | +3.2 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
62 years, 1904 to 1995A day with at least 49.8 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 125.7 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 | 49.8 mm (2.0 in) | |
| 5 years | 66.9 mm (2.6 in) | |
| 10 years | 79.4 mm (3.1 in) | |
| 25 years | 96.7 mm (3.8 in) | |
| 50 years | 110.7 mm (4.4 in) | |
| 100 years | 125.7 mm (4.9 in) | Longer than the 62 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, 62 years of values from 1904 to 1995.
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: 127.0 mm (5.0 in) in 1994; 99.1 mm (3.9 in) in 1949; 91.9 mm (3.6 in) in 1947.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Grand Haven Fire Dept, at 1959 and 1976. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1959 ran 0.2 C (0.4 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1976 ran 0.3 C (0.6 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1959 | -0.2 | -0.4 | likely | 5 |
| 1976 | +0.3 | +0.6 | likely | 5 |
Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
