[16] [20] On average, dew points range from 31 °F (−1 °C) in April to 58 °F (14 °C) in August. [21] Occasionally, dew points can drop as low as 0 °F (−18 °C), or they can exceed 70 °F (21 °C) during periods of strong monsoon activity—creating muggy conditions in the area.

The dew point temperature equals the air temperature when the air is saturated with water; in all other cases the dew point will be less than the air temperature. [ 6 ] : 129 In technical terms, the dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same ...
The average July high is about 104 °F (40 °C), with the average January low being about 36 °F (3 °C), still above freezing. Bestplaces gives Metropolitan Phoenix a comfort index [a] of 44/100, which is also the national average. [23] Below is a chart showing climate data collected from Sky Harbor Airport. Due to the vast area covered by the ...
In such diagrams, temperature and humidity values (represented by the dew point) are displayed with respect to pressure. Thus the diagram gives at a first glance the actual atmospheric stratification and vertical water vapor distribution.
A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.
Station model plots use an internationally accepted coding convention that has changed little since August 1, 1941. Elements in the plot show the key weather elements, including temperature, dew point, wind, cloud cover, air pressure, pressure tendency, and precipitation. [2] [3]
The major use for skew-T log-P diagrams is the plotting of radiosonde soundings, which give a vertical profile of the temperature and dew point temperature throughout the troposphere and lower stratosphere.
