Dear Jerold, The concept of zero percent relative humidity — air completely devoid of water vapor — is intriguing, but given Earth's climate and weather conditions, it's an impossibility. Water vapor is always present in the air, even if only in trace amounts.
1. Portugal. Located on the Iberian Peninsula in the southwest of Europe, Portugal's climate is considered both Mediterranean and temperate maritime with mild summers and cool but not cold winters.
A relative humidity of 0% would make it feel like it's only 69° F (20.5° C). On the other hand, a relative humidity of 100% would make it feel like it's 80° F (26.6° C).
Adelaide enjoys the lowest humidity of any Australian city. Autumn (March-May) In autumn, the weather is pleasant with average temperatures between 12.7 - 22.7°C (55 - 73°F) and very little rainfall.
Nevada has the lowest humidity. It's no coincidence the state is known for its desert and arid climate. With average relative humidity sitting at 38.3%, Nevada has the lowest relative humidity (when comparing states) in the country.
Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent.
The heaviest rainfalls and highest humidity are in the northwest of the country at the Pacific Ocean. New South Wales and Queensland on the western coast to the Pacific Ocean lie in a subtropical climate zone. This means a high humidity almost all year round with higher temperatures and pronounced rainy seasons.
The city of Perth has the best weather/climate in Australia. The city enjoys a temperate Mediterranean climate with hot and dry summers and mild but wet winters. Perth is also the sunniest capital city in Australia and is considered one of the hottest experiencing over 250+ days of sunny blue skies.
Eyes become dry and irritated, skin gets flaky and itchy and the low humidity inflames and dries out the mucous membrane lining the respiratory tract. As a result, the risk of cold, flu and other infections is substantially increased.
If you were in a controlled chamber at 70F and 0% relative humidity; then your tears would dry up quickly, your skin would begin to dry. Your lungs and mucous membranes would lose moisture very fast. You could dehydrate in a few hours.
The Canary Islands climate is considered the best climate in the world, thanks to the year-round pleasant, mild temperatures. This is added to the facts that it rarely rains in the archipelago and that it is the region with the most hours of sunlight per day in Europe.
#1 Portugal. Portugal has some of the mildest weather in all of Europe with wet, temperate winters and dry, warm to hot summers, depending on location. Bordered by over 1,100 miles of Atlantic coastline the country has a mild Mediterranean climate with some variations throughout.
Tasmania scored highly in the report in terms of its climate, electricity supply, agricultural resources and population density.
Australia, however, is strikingly diverse with climate matches to India, California, South Africa, central Italy and Buenos Aires. Perhaps surprisingly, many parts of the neighbouring island of Tasmania are closer to the United Kingdom and Ireland than the sunnier regions of Australia's climate map.
La Nina has resulted in a humid summer for much of eastern Australia. This climate pattern typically causes warm, humid air to rise from the western Pacific Ocean, ultimately leading to greater cloud formation, increased rainfall, and higher humidity along Australia's eastern seaboard and tropical north.
The rangelands of arid and semi-arid Australia
Australia is the driest inhabited continent in the world; 70% of it is either arid or semi arid land.
The wettest city in the world is Buenaventura, where it rains 258 days per year. Australia's rainiest city is Cairns in Queensland, with 117 days of precipitation. The UK's wettest city is Londonderry in Northern Ireland (147 days). The wettest city in the US is Hilo, Hawaii (211 days).
less than or equal to 55: dry and comfortable. between 55 and 65: becoming "sticky" with muggy evenings. greater than or equal to 65: lots of moisture in the air, becoming oppressive.
