Inaccurate temperature

I downloaded Ventusky at the recommendation of a friend but the temperatures are always off in comparison to every other app I have and any online weather resources. Today the temperature is currently 51° but my watch app says it's 41° and iPhone app says it's 44°. I have changed settings but nothing resolves this issue.

Which location is it, please? Ideally, send us a screenshot of main screen with temperature map so we can see where, when, and under what settings the value does not match.
