Summer-time values in Northern latitudes rarely exceed 8. This typically occurs between 11:30 and 12:30, or between 12:30 and 13:30 in areas where daylight saving time is being observed.

The higher the UV index, the more intense the radiation and the greater the risk of skin damage. Secure .gov websites use HTTPS Estimated to have over 106,000 new cases in 2021 alone (roughly 5.6% of all new cancer diagnoses this year), melanoma is currently ranked as the 19th most common cancer in the world (2)(3). The UV index is a measure of the amount of ultraviolet radiation reaching the earths surface. WebThe monthly average maps use the same color scale and class breaks as the annual average map for the contiguous United States for the purpose of showing monthly variation relative to the annual average. WebThe Global Solar UV Index (UVI) The UVI is a simple measure of the UV radiation level at the Earth's surface. When the day's predicted UV index is within various numerical ranges, the recommendations for protection are as follows:[18][27]. Factors like the Earths elliptical orbit shape, lower overall pollution levels, and less population density results in countries in the southern hemisphere near the equator getting an estimated 15% more UV radiation exposure than those in the northern hemisphere (13). About the UV index Toggle navigation. All information these cookies collect is aggregated and therefore anonymous. sun-safe activities is a great way to reduce your risk of developing skin cancer. Exposure to solar ultraviolet (UV) radiation Data by country You are here: By category; Public health and environment; Ultraviolet (UV) radiation; Exposure to solar ultraviolet (UV) radiation; Regions. If you dont feel the hot rays of the sun you wont get sunburnt. UV Index The UV index is used to forecast the strength of the sun's ultraviolet rays. WebThe Cancers Attributable to UV Radiations. JavaScript appears to be disabled on this computer. The top 20 countries for skin cancer diagnoses (and their average summer UV index) are (7): #1 Australia (average UV index of greater than 12) #2 New Zealand (average UV index of greater than 11) #3 Norway (average UV index of 5 or less) #4 Denmark (average UV index of 6 or less) Integration of these values using all the intermediate weightings over the full spectral range of 290nm to 400nm[13] produces a figure of 264mW/m2 (the DUV), which is then divided by 25mW/m2 to give a UV index of 10.6. Typical UV Index values for a range of cities worldwide are specified for the 21st of each month based on calculations with the radiation transfer model STAR. The higher the UV index, the more intense the radiation and the greater the risk of skin damage. It is created daily by the National Weather Service. Thus UV radiation levels vary with time of day and time of year.Latitude: the closer to equatorial regions, the higher the UV radiation levels.Cloud cover: UV radiation levels are highest under cloudless skies but even with cloud cover, they can be high. Melanin does help to prevent UV radiation damage, but it can also hide the early signs of skin cancer, leading to people with these skin complexions being diagnosed at later and more severe stages of the disease. The values of the Index range from zero upward and the higher the Index value, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur. March. The coldest month in Auckland, New Zealand, is July , with an average high-temperature of 13.8C (56.8F) and an average low-temperature of 10.4C (50.7F) . The most common types of non-melanoma skin cancers are basal cell carcinomas and squamous cell carcinomas, both of which have a lower mortality rate than melanoma (1). However, sunscreen represents a last line of defence, and should never be used to prolong the duration of sun exposure. WebThe first month of the spring, March, is also a hot month in Panama City, Panama, with an average temperature ranging between max 34.8C (94.6F) and min 18.4C (65.1F).
