If you are using the in game live weather, you can get metar reports online for almost every airport in the world by simply searching for “metar XXXX” where XXXX is the ICAO of your airport. I start every flight with this information staged in two browser tabs.
Also, like I did in the real world, before getting the metar information set your airplane altimeter until the altitude reads the charted airport altitude. Then verify what that setting is with the published metar data. Metars are NOT published every minute so event he most current one can have dated information, particularly when dynamic weather systems are present. You want your altitude and actual airport altitude to be correct.
