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

21 years with a frost

Across 21 years with a frost, the median last spring frost at Mexicali (Dge) falls on 3 February and the median first autumn frost on 10 December, which leaves a median of 312 days between them.

Frost dates and growing season at Mexicali (Dge)
Measure	Median, all years	Earliest period	Recent period (1950 to 1985)	Recent against earliest	Fitted trend
Last spring frost	3 February	n/a	3 February	n/a	n/a
First autumn frost	10 December	n/a	10 December	n/a	n/a
Growing days	312 days	n/a	312 days	n/a	n/a

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, 1950 to 2012

A day with at least 19.0 mm (0.7 in) of rain is expected about once in 2 years. A day with at least 68.5 mm (2.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Mexicali (Dge): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	19.0 mm (0.7 in)
5 years	31.5 mm (1.2 in)
10 years	40.0 mm (1.6 in)
25 years	51.2 mm (2.0 in)
50 years	59.7 mm (2.4 in)
100 years	68.5 mm (2.7 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 1950 to 2012.

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: 62.0 mm (2.4 in) in 1977; 55.4 mm (2.2 in) in 1972; 50.0 mm (2.0 in) in 1982.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Mexicali (Dge), at 1962 and 1977. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1962 ran 0.6 C (1.1 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1977 ran 0.6 C (1.1 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Mexicali (Dge), against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1962	-0.6	-1.1	likely	5
1977	+0.6	+1.1	possible	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.
