When embedding the map, temperature is not displayed correctly

[miroruse]

The code I am using to display the wind/temp is the standard, generated by the system for the location.

What happens is, on the website link
the knots are ok, but the temp C is displayed in strange values. While the real one is 20 degrees celsius, the embedded map displays sometimes 60, 70 or even 40 degress.

Why is that happening?
