Searching for the current time that I am sending this message 12:00 UTC-3 15:00 (UTC) we would have the 3rd position of the array index 2 (1744902000000) and the equivalent value in the temp-surface would be (302.03165707353776) K

Since I am in Brazil, I need to convert to Celsius, which would give me an approximate value of 28.881657073538 °C. But when comparing this temperature with what is shown on your official map, the value is not the same. You present the temperature as 25 °C, which is a considerably different value from what is presented in the API.

I would like to know why this difference exists, if it is supposed to be like this, and if so, a prediction of when this could be resolved.
