Seeming as there's a conversation about UV indexes going on in another thread and it's close to the midpoint in the astronomical year wherever you are in the world with the sun directly above the Equator, what is the UV index in your location? Here, at 51 degrees N and at sea level it's 3, though there is a 4 forecast for one day next week. The most we generally get here is around 6 or 7 and the UV is 1 for three to four months in the winter. If it was sunny tomorrow I could spend the whole day outside unprotected and would have no danger of sunburn. There's about a four-month window between mid-April and mid-August when I'd have to put suncream on if I was outdoors in the sun for, say, 1-2 hours or more.

Clear sky forecast for today is about 5.5 in far north, 5 at Auckland, 4 at Wellington and 3.5 in the far south. (all coastal cases)

A little lower than I'd have thought, would they be higher on your autumn equinox than the spring equinox? I'm not sure but I think on our spring equinox we'd be more likely to get a 2 than a 3.

I love that about England. I like sunshine, but I hate the burn and skin damage.
Was supposed to be partly cloudy today with a forecasted index of 6 (that didn't happen). The forecast shows a cloudless sky for Sept 28/29 and it is still 6.
I found this neat EPA site that gives past years forecasts for cities in the US. Below is mine for 2010. The clear sky index assumes a cloudless sky vs the forecasted. I don't think we get anywhere near Australia or NZ level which suit me fine.

Is this very high or dangerous? the weather is in the high 60s and low 70s this days. I always heard that the UV index is very dangerous here in the summertime (from december till april) and in the news and elsewhere they always suggest NOT to live the house withouth sunblock cause you can easily burn. In those months the weather is aroud 90f.
I guess when the days are hotter the UV is higher, right?
In the summer, we get 9 fairly regularly, and 10 once in a while, usually close to the solstice.
How much does the UV need to be in order for sunburn to be likely? I often forget sunscreen on sunny days. Usually I'm ok, once in a while I burn a bit. Hmm...my skin color looks different...that's not tan, that's red skin. Never got a painful sunburn, at least.

Not sure, can't see any year-round data at present. But even in the southern interior at Lauder (45S) the summer average appears to be about 11-12.
Here are the forecasted UVI for the next week. From what I gather winter UV readings are comparable to NH latitudes in winter, and show the biggest difference in summer. There were mild sunburn days amongst fellow workers on a couple of days in late June, I don't know why that was .I remember autumn equinox UVI at about 7 or 8. A high summer reading here is 13 or 14.
