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 ...
It's estimated that a frost may occur earlier than the given date 30% of the time. So use the first frost date as an estimate—it doesn't hurt to get your garden ready a bit in advance of it.
The blue numbers are the amount of precipitation in either millimeters (liters per square meter) or inches. The red numbers are the average daily high and low temperatures for each month, and the red bars represent the average daily temperature span for each month. The thin gray line is 0 °C or 32 °F, the point of freezing, for orientation.

These measurements reflect averages over a large region and so are lower than the maximum point surface temperature. [ 6 ] Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at 81°48′S 59°18′E / 81.8°S 59.3°E ...
The temperature at which frost will form is called the dew point, and depends on the humidity of the air. [1] When the temperature of the air drops below its dew point, excess water vapor is forced out of solution, resulting in a phase change directly from water vapor (a gas) to ice (a solid).
The dew point is a saturation point. When the dew point temperature falls below freezing it is called the frost point, as the water vapor no longer creates dew but instead creates frost or hoarfrost by deposition. [17] The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the ...
The flags and pennants point to the low pressure, so it is possible to determine at which hemisphere the station is standing. The barbs in the figure at the right are located at the Northern Hemisphere , because the wind is circling counter clock-wise around a low-pressure area at the Northern Hemisphere (the wind is blowing in the opposite ...
