Scientists still have to validate the reading of 130 degrees Fahrenheit on Sunday, the equivalent of 54 degrees Celsius. In the popular imagination, Death Valley in Southern California is the hottest place on earth.

The concept of zero percent relative humidity — air devoid of water vapor — is intriguing, but given Earth’s climate and weather conditions, it’s impossible. Water vapor is always present in the air, even if only in minute quantities.

The highest dew point ever recorded, 95°F (35°C), was recorded at Dhahran, Saudi Arabia, on July 8, 2003. With an air temperature of 108°F (42°C) the heat index was 178°F (81°C).

A dew point between 55°F and 60°F is noticeably humid. It’s muggy when the dew point is above 60°F, and it’s uncomfortable outside when it ticks above 65°F. Any dew point readings above 70°F are oppressive and even dangerous, the kind of stickiness you experience in the tropics or during a brutal summer heat wave.

What are the highest dew points, worldwide and for the U.S.? The world’s highest reported dew point is 95 degrees, recorded on July 8, 2003, at Dhahran, Saudi Arabia, located on the Persian Gulf. With a 95-degree dew point, the lowest possible heat index there (temperature also at 95 degrees) would be 161.

If it’s 100 and the dew point is 72, relative humidity would be 40 percent. In the winter, you could have a 40 degree day with a dew point of 38, and relative humidity would be 93 percent.

It is relative to the temperature and moisture content of the air. In very warm, humid conditions, the dew point temperature can reach 75 to 77 degrees F, but rarely exceeds 80 degrees. That means if you hear someone say it is 90 degrees and 90 or 100% humidity they are absolutely wrong.

The dew point is the temperature to which air must be cooled to become saturated with water vapor. When cooled further, the airborne water vapor will condense to form liquid water (dew). The measurement of the dew point is related to humidity. A higher dew point means there is more moisture in the air.

One of the important weather factors that growers should pay attention to in the frost forecast is the dew point temperature. The dew point temperature is the temperature to which the air must be cooled before dew or frost begins to form. Therefore, knowing the dew point gives an idea of how moist or dry the air is.

Does mold die in the winter? Cold weather will not kill mold. Mold spores are opportunistic in the sense that they wait for the right conditions and then begin to spread. Extreme temperatures do not kill mold, but they can deactivate them.

Contrary to popular belief, washing your hands in hot water isn’t the best way to go. The oils on your hands hold bacteria and germs, and warm water and soap is effective enough to remove them. Warm water also trumps cold water, which is less effective at removing oils and germs.

Foaming hand wash Another popular household brand name, Dial has also used clinical testing to prove its antibacterial hand soap kills up to 99.99% of germs and bacteria, although the brand clarifies that the foaming soap is tested on common household germs, as opposed to, say, a respiratory pathogen.
