UV Discrepency

What's up with this? Cloud cover? Both around 11:45 am today. Top one is The Weather Network, I think the bottom one is called Weather Online.

Speculation mistake. Also they may measure it at different points in the city. Curious myself

Maybe the "very high" one is measured on the Moon.....

The higher the Sun gets, the higher the UV (less atmosphere to pass through). This is why the "very high" is at 1pm, when the Sun is at its highest.....

Of course, the "Daily Max" might be based on prediction.

Then, there is the smoke from the Alberta wildfilers to consider. Smoke really absorbs UV and other high frequencies....

May be the app did not refresh on the 2nd one.
