Willyweather seems to have the incorrect UV index data. It shows 12.8 in my area, but apple weather says UV is 6 which seems correct to me as it is cloudy / drizzling now.
You can see from OP's screenshot that they're only viewing the forecasted UV index. Your Apple Weather app is more accurately using a source providing a measured index.
If you want a fairly reliable official source, you can use ARPANSA's website and set the location to Sydney and see that the index is currently correctly measured as 1.3
albedo effect. the rays bouncing off the ground back up to the sky are restricted in their dispersal and hit the clouds and then are returned back to the ground. is the basic terrible description of what is happening.
If it's midday, protect from the sun, which was when OP's post was made. The cloud cover absolutely isn't providing consistent enough protection at the time of day when the UV is the strongest.
Always be sun safe. Are you out there really thinking you can rawdog it?
And if you look at the actually measured readout you will notice it greatly spiked up and dow throughout the day. It was never low for long. That's why cloud cover isn't a reliable protector, to much scattering and clouds don't stay consistent.
That can’t be right. There isn’t any direct sun whatsoever. I’m still staying sun safe but there’s no way it’s the same today as it was yesterday. Impossible.
Jesus criminey the responses on this post. You'd think this was a brigade against wearing sunscreen. All OP said was "be sun safe" you dolts.
Of course it's a forecast. But UV should not be fucked around with and cloud cover does NOT diminish it enough to prevent sunburn or sun damage. And UV radiation exposure is CUMULATIVE. UVA is gonna do its bad cancer creating shit regardless of whether it's a 6 or 12.
And if you look at the real-time data ARPANSA provided that you fervently linked to as counter evidence (for some insane reason this needs counter evidence?), it's averaging pretty close to the curve, and not in the green zone.
Wear sunscreen and sun protection when you go outside. Just follow that as a general rule, y'know?
If you other commenters are suggesting people try to be sun safe based on the realtime data only, that's like trying to prevent pregnancy based on mapping someone's cycle -- extremely lossy and rarely safe.
Uh, no? What kind of misinformation BS is going on here in this thread? At best they can only say there hasn't been enough research on cloudy days but the risk is very much there. https://www.abc.net.au/science/articles/2012/01/24/3413924.htm . Every dermatologist in their right mind has for decades mentioned how much UV damage can still be done on cloudy days so unless you're being influenced by the new TikTok trend that's bringing back tanning beds and smoking, I don't know where you're getting your information and no one in this thread should be listening to random commenters.
And remember there are multiple types of UV. UVA passes through many things more easily than UVB and UVA does a lot of long term damage.
Please check the source first: that graph is an assumption and not accurate.

In a nutshell: cloud cover can limit UV exposure but don't rely on it.
Wow, way lower than that graph. Good to know.
That doesn't look right, is that forecast or real time UV? It's way lower with the cloud cover in Sydney today.

Select locstion: Sydney from that drop down list
Currently 1.2?

This is a forecast, not the measured UV index. The current UV index is around 2 in Sydney: https://www.arpansa.gov.au/our-services/monitoring/ultraviolet-radiation-monitoring/ultraviolet-radiation-index
Maybe delete this post aye

Why does the weather app on the iPhone say the UV is only 6? Which would be more accurate? Either way stay safe and put some sunscreen on!

Is this measured or calculated? Because according to the ARPANSA uv index the UV is currently at 1.0 in Sydney?
It's windy but humid. UV rays will be high. I took my dogs for a walk but forgot to put on sunscreen. Need to remember for the future.
I always find I get more sunburnt in cloudy weather. I wonder why. Does anyone know the science behind it?
Probably less conscious of the sun and less likely to take proactive action against getting burnt
True, you’re right.
Partly less conscious of it, but the cloud also scatters it so I find you get it from more angles.
Similar to the snow effect.

Use the SunSmart app run by cancer council vic. I Use it everyday and gives you a nice time graph when to protect and when ok not to.
If it's midday, protect from the sun, which was when OP's post was made. The cloud cover absolutely isn't providing consistent enough protection at the time of day when the UV is the strongest.

Just about to take the dog for a walk, thanks for the reminder!
Also, air quality. It's currently 2 to 2.5 x WHO recommended safe levels. I had to abandon today's plans as I can feel it in my lungs
Which App is this
WillyWeather
lol wtf

Bruh when you see cloud cover this thick, UV doesn’t go through at all.
