Climate data for Houston was first collected in 1882. The first full year of data was collected in 1889. There was a significant data gap during 1905-1906 and those years have been deleted from these Top 10 lists. Curiously enough, the latter half of 1905 and the first half of 1906 was one of the driest on records across Southeast Texas.

The first weather office and climatological data gathering point was located at the Cotton Station Building in downtown Houston (if there was a downtown then). Data was collected from this location until September 1909.

The weather office was relocated to the Stewart Building (located at Preston and Fannin) from September 1909 through February 1926.

The weather office was relocated to the Shell Building (located at Texas and Fannin) from March 1926 through August 1938.

The weather office was relocated again to the Federal Building (located at Franklin and Fannin) from August 1938 through March 1961. All locations listed above were within 1/4 mile of each other and should provide a good continuity of climate data.

Temperature, rainfall and other climate information began to be reported from Houston Intercontinental Airport (a.k.a. Houston Hobby) in August of 1960. The downtown weather office remained open and also archived climate information. This is where it gets a little confusing. An LCD (Local Climatological Data) summary was prepared for both Houston Hobby Airport and the downtown site. NCDC (the National Climatic Data Center) stopped publishing an LCD for the downtown site in August of 1967. NCDC used the airport site as the official climate data gathering point (1960 and beyond) and this TOP 10 data has mirrored that effort. Weather records for Hobby Airport date back to July of 1930.

In June of 1969, the official weather station was moved to Intercontinental Airport (IAH), which is twenty-three miles north Hobby Airport. Weather records have been gathered at IAH ever since. ASOS was commisioned at IAH in June of 1996. There is a rather marked departure in the climatological record of Hobby and Intercontinental Airports. Please be aware of this disparity when reviewing or disseminating climte information.
