The fitted trend in annual mean temperature here over 1894 to 2020 is 0.00 C (-0.05 to 0.05) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.00 F (-0.09 to 0.09) per decade. The slope is a straight line fitted to 63 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.00 C (-0.05 to 0.05) per decade | 0.00 F (-0.09 to 0.09) per decade | 1894 to 2020 | 63 | Not clearly different from zero |
| Mean daily maximum | -0.08 C (-0.13 to -0.02) per decade | -0.14 F (-0.24 to -0.04) per decade | 1894 to 2020 | 63 | Fall |
| Mean daily minimum | 0.08 C (0.01 to 0.14) per decade | 0.14 F (0.02 to 0.25) per decade | 1894 to 2020 | 63 | 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
63 years with a frostAcross 63 years with a frost, the median last spring frost at Houston falls on 24 April and the median first autumn frost on 12 October, which leaves a median of 171 days between them.
In 1967 to 2020 the median growing season was 179 days. That is 11 days more than in 1894 to 1963.
Fitted over all years, the growing season changes by +2.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1894 to 1963) | Recent period (1967 to 2020) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 24 April | 30 April | 21 April | 9 days earlier | -1.4 days per decade |
| First autumn frost | 12 October | 9 October | 15 October | 6 days later | +0.9 days per decade |
| Growing days | 171 days | 168 days | 179 days | 11 days more | +2.3 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
77 years, 1894 to 2023A day with at least 67.9 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 155.3 mm (6.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 67.9 mm (2.7 in) | |
| 5 years | 88.7 mm (3.5 in) | |
| 10 years | 103.5 mm (4.1 in) | |
| 25 years | 123.3 mm (4.9 in) | |
| 50 years | 139.0 mm (5.5 in) | |
| 100 years | 155.3 mm (6.1 in) | Longer than the 77 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, 77 years of values from 1894 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: 177.5 mm (7.0 in) in 2017; 134.6 mm (5.3 in) in 1956; 124.5 mm (4.9 in) in 1979.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Houston, at 1963. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1963 ran 0.4 C (0.8 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1963 | +0.4 | +0.8 | 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.
Climate Twins
1989 to 2020 against 1961 to 1990Over 1989 to 2020, Houston had a mean temperature of 13.2 C (55.8 F) and 1,113.9 mm (43.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Culpeper (United States, 1,228 km away), Williamson (United States, 850 km away) and Galena (United States, 150 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Culpeper | United States | 1,228 km (763 mi) | 13.1 C (55.6 F) | 1,083.5 mm (42.7 in) | 0.40 |
| Williamson | United States | 850 km (528 mi) | 13.6 C (56.4 F) | 1,121.8 mm (44.2 in) | 0.46 |
| Galena | United States | 150 km (93 mi) | 13.5 C (56.3 F) | 1,107.9 mm (43.6 in) | 0.48 |
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.
