The Yellow Disc in the Sky
The main weather hazard faced by Napier’s residents is the strength of the sun – particularly in summer.
- In high summer, the sunshine in New Zealand is really strong. You’ll burn more easily in New Zealand than anywhere in the Mediterranean.
- There are three reasons why the sun in the Southern Hemisphere is so strong.
- There is less ozone to block the UV rays that cause sunburn.
- Earth’s orbit takes it closer to the sun during the southern summer than during the northern summer.
- There is less pollution in the southern hemisphere to block the UV rays.
- The sun’s burning strength is measured by the UV index. The highest possible UV index at sea-level is about 20. This can occur at midday in equatorial regions. Any reading higher than 10 is extreme in terms of skin-damage.
- The UV Index in the Mediterranean in high-summer reaches 9 or 10.
- The people in Florida are fried on a just a few days each summer when the index reaches 12.
- In New Zealand the summer index often exceeds 12.
