Highest dew point temperature: A dew point of 35 °C (95 °F) — while the temperature was 42 °C (108 °F) — was observed at Dhahran, Saudi Arabia, at 3:00 p.m. on 8 July 2003. [ 202 ] Highest heat index : In the observation above at Dhahran, Saudi Arabia, the heat index ("feels like" temperature) was 81.1 °C (178.0 °F).
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness.Temperature is measured with a thermometer.It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance.
A heat storm is a Californian term for an extended heat wave. Heat storms occur when the temperature reaches 100 °F (37.8 °C) for three or more consecutive days over a wide area (tens of thousands of square miles). [20] The National Weather Service issues heat advisories and excessive heat warnings when it expects unusual periods of hot weather.
October 1952 – Romania was hit by very hot weather. Temperatures reached 39.0 °C (102.2 °F) on 2 October, with Bucharest reaching 35.2 °C (95.4 °F). Temperatures on the night of 2–3 October were also just under 26 °C (79 °F). 1955 – 1955 United Kingdom heat wave was a period of hot weather that was accompanied by drought. In some ...
Highest temperatures ever recorded in Spain [ edit ] On July 30, 1876 and August 4, 1881, temperatures of 51.0 °C (123.8 °F) and 50.0 °C (122.0 °F) [ 1 ] were both reported for Seville : these readings are unreliable, since they were measured under a standard exposure and in poor technical conditions.

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 .
A period of weather characterized by excessively high temperatures, which may or may not be accompanied by high humidity or by drought. Very hot weather is often only referred to as a heat wave if the temperature is abnormal relative to the typical climate for a given location during a given season. Contrast cold wave. heavy snow warning
The temperature reached in a process was estimated by the shrinkage of a sample of clay. The higher the temperature, the more the shrinkage. This was the only available more or less reliable method of measurement of temperatures above 1000 °C (1,832 °F). But such shrinkage is irreversible. The clay does not expand again on cooling.
