temperature wrong - São Paulo - Brazil

[mmachado]

For days the temperature in the city of Sao Paulo, Brazil, shows a mistaken temperature as to reality. It has been doing over 35ºC in the afternoons but the Windy points 21ºC. The difference is brutal

Hi @mmachado , I checked the temperature range for today in São Paolo - Brazil.
As you can see the GFS forecast model is more accurate in Brazil.

@mmachado

In addition, your town is a big one with probably the « urban heat island » effect.

Global models like ECMWF and GFS are not really able to take this effect into account. But this effect is generally few degree more than countryside.
In Saõ Paulo there are 4 weather stations that you can see on Windy by selecting Reported temperature in right low corner.
Then when you click on a station you get a comparison of reported temperature and forecasted temperature:

You see that forecasted temperatures (dashed line) matches well enough with the observed temperatures (pink curve). You can check these 4 weather stations.

@BarboraSamkova e além disso estão considerando em cor de laranja ou vermelho as temperaturas abaixo de trinta e três graus? Acredito que estão seguindo essa agenda errada do aquecimento global, estão errados, considera-se em laranja ou vermelho as temperaturas acima de trinta e três graus

@alcfox hi, the default range of colors for temperature looks like this:

If you want, you can customize the colors by going to settings (Opções) and then clicking on Customize Color Scale (Personalizar a escala de cores) on the bottom of the panel.
