Since, we focused on annual climate. Now, let's look at by seasons in Upper Texas Coast. Wondered what is the wettest and driest season ever in the Upper Texas Coast?

Winter
Average Rainfall Total
10.69

Median Rainfall Total
10.17

Standard Deviation
3.469628

Top 10 Wettest Winter
1991-1992 23.72
1990-1991 18.35
1923-1924 18.31
1931-1932 18.06
1933-1934 17.56
1960-1961 17.20
1965-1966 16.48
1902-1903 16.32
1945-1946 16.10
1997-1998 15.94

I remember winter of 1991-1992 being very wet. Winter of 1923-24 is a stark contrast to summer of 1924.

Top 10 Driest Winter
2008-2009 2.84
1970-1971 3.89
1961-1962 4.51
1917-1918 5.46
1975-1976 5.57
1906-1907 5.90
1901-1902 6.00
2005-2006 6.01
1999-2000 6.02
1908-1909 6.11

I notice drier winters tend to be warmer in general. Dry and warmer winters are typical in La Nina.

Spring
Average Rainfall Total
10.76

Median Rainfall Total
10.37

Standard Deviation
4.452003

Top 10 Wettest Spring
1997 22.26
1900 21.97
1957 19.39
1922 19.38
1993 19.28
1944 19.04
1941 18.99
1905 18.31
1914 18.26
1991 17.62

I remember spring of 1997 being quite wet. Heavy rain would fall every week from March to May.

Top 10 Driest Spring
2003 2.56
1963 2.91
1996 3.13
1978 3.26
1998 3.32
1960 4.57
1899 5.02
1958 5.30
1961 5.33
1898 5.59

Some years with dry springs have given way to wet summers, like 1960 and 1961.

Summer
Average Rainfall Total
13.066522

Median Rainfall Total
12.2

Standard Deviation
4.904957

Top 10 Wettest Summer
1960 24.46
1981 24.06
2007 24.01
2001 23.16
1942 23.10
1961 23.06
1919 22.82
1983 21.93
1945 21.66
1973 21.49

Summer of 2007 was quite wet from what I remember. It rained almost everyday. A summer without the Sun and heat for the most part. Not surprisingly, all the wet summers had tropical cyclones making landfall on the Upper Texas Coast during the summer or in the fall.

Top 10 Driest Summer
2009 5.17
1924 5.79
1980 5.87
2000 5.89
1954 6.18
1956 6.19
1896 6.28
1930 6.49
1948 6.55
1951 6.56

Gees, not only Summer of 2009 was hot, it was bone dry! :o It was even drier than 1980, which is one of the hottest summers! 2009 also has the driest winter on record. Talk about a crazy year! A wet winter of 1923-24 gives way to dry summer of 1924. 1998 is not one of the top 10 driest summer, despite being one of the hottest summer.

Fall
Average Rainfall Total
13.31

Median Rainfall Total
12.39

Standard Deviation
5.399548

Fall is the wettest season of the year. Not surprisingly, major floods have occurred from September to November. Tropical cyclones make landfall usually in September.

Top 10 Wettest Fall
1913 29.03
1998 27.60
2002 26.15
1919 24.82

1925 22.76
1986 22.40
1973 22.40
1984 21.92

Fall of 1998 was very wet. First there was Tropical Storm Frances, than heavy rain in October and November on top of a very warm month, on heels of a hot summer.

1978-1979 50.700
1939-1940 51.033
*No data for December of 1894

If you were feeling colder this past winter, it was cooler than normal. 2009-2010 winter is one of the coldest winters ever for the Upper Texas Coast. It is up there with 1977-1978 and 1894-1895. February 1895 had the big blizzard on February 13-14, 1895. 2009 was quite a contrast from hot summer to cold winters. Interesting to note from 1976 to 1979, there were strings of cooler winters.

1924 83.8333
2000 83.8333
2005 83.7000
1918 83.6667

Summer of 2009 was very hot. It is only second to the Summer of 1998. It even beats Summer of 1980, a notoriously hot summer. 2000 is also one of the hottest summers on record and it produced many heat waves.

Top 10 Coolest Summer

Cool summers are rare. Some summers do not reach 100 degrees. Since 1998, every summer has hit 100. 1976 had the coolest summer recorded. Also, there were strings of cool summers from 1972 to 1974.

Top 10 Warmest Fall
1931 74.5000
1927 74.3000

1898 68.6333
1936 68.7333

October 1949 is the wettest month ever in the Upper Texas Coast due to a hurricane and a few days later, heavy rain. Many floods have occurred in October, like in 1994. Also, October had 0 inches of rain in 1924 again and 1952. Having 2 months with 0 inches of rain is just crazy.

Notice months with snow are also some of the driest Decembers on record, 1989 and 2008. 1989 was also one of the coldest Decembers on record, when the lows reach into the single digits! December 1991 had a huge flood event from Central Texas to East Texas. Quite a flood event it was for Texas.

Next, we shall look at monthly temperatures for the Upper Texas Coast. I shall return.

Seems like some years have many record warmth like 1998, while some have record coolness, like 1976 and 1978. I will explore if there is a connection between January-May rainfall and temperature and tropical cyclone landfalls on the Upper Texas Coast.
