The highest temperature ever measured in Texas was 120 °F (48.9 °C), recorded on August 12, 1936 in Seymour, during the 1936 North American Heatwave, and again on June 28, 1994 in Monahans. The lowest temperature ever measured in Texas was −23 °F (−30.6 °C), recorded on February 8, 1933 in Seminole. [29]
The precipitation threshold (in millimetres) involves first multiplying the average annual temperature in °C by 20, then adding 280 if 70% or more of the total precipitation is in the high-sun summer half of the year (April through September in the Northern Hemisphere, or October through March in the Southern), or 140 if 30–70% of the total ...
This phenomenon causes an extremely large daily temperature range. Specifically, temperatures in a low elevation inland desert can reach 40°C to 50°C during the day, and drop to approximately 5°C at night; the daily range is around 30 to 40°C. [3] There are some other reasons for significant changes in temperature in tropical deserts.
The city's all-time recorded high temperature is 113 °F (45 °C) during the Heat Wave of 1980. In July and August, the average high temperature is near 96 °F (36 °C), while the average nighttime low temperature is around 77 °F (25 °C). Days with temperatures exceeding 100 °F (38 °C) happen at least several times during the summer every year.
The local weather service office issued an excessive heat warning through Tuesday that included a forecast of 120-degree highs for parts of the Rio Grande Valley.
Temperature lag, also known as thermal inertia, is an important factor in diurnal temperature variation. Peak daily temperature generally occurs after noon, as air keeps absorbing net heat for a period of time from morning through noon and some time thereafter. Similarly, minimum daily temperature generally occurs substantially after midnight ...

This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
