Theres a whole forum for that. Thats a great place to discuss 30 year averages all over the place, not just here. You could link those discussions here anytime. Too many posts here about a warm day or a string of warm days this year are the fault of man made global warming especially this year, when we have 1 really above normal month since December. It’s just thin gruel in the context of the weather.
global climate writ large, thats the right place because this is a hot year on a global scale. It’s just not that hot here this year in extremis over the last 40. So lets keep it to weather.
