Good Morning nobueno,
there is a way to ignore the temperature data from the default station from your area
One of the most common reasons why it is reading higher than usual is
that it might be in direct sunlight throughout most of the day, or it might
not be in an effective radiation shield, or it might be located near external heat sources,
such as concrete, asphalt, A/C Units, dark fences, dark surfaces, etc.
My advice is to go with another nearby weather station that is more accurate and reliable.
Usually ones that get proper ventilation and have effective radiation shields like the Davis Vantage Pro2, the Davis Vantage Vue, and the Ambient Weather WS-1000s series, just to name a few. For a while i had this same problem with my La Crosse Weather Station reading to high of Temperature.
That was because i did not have the sensor sighted properly. After relocating it and trying some different things,
I than upgraded to the Davis Vantage Pro2 6152. Ever since the Upgrade, my temperature
readings have been accurate enough to meet CWOP Standards. The main unit is located in an open Grassy area 5 feet off the ground. I have seen multiple other weather stations with higher than usual Temperature readings.
And i have to say that is quite common, especially in highly populated areas.
I hope this helps for you to solve your problem. Also, welcome to the WxFourm Community!
