Weather App Data Inconsistency

My roommates’ weather apps consistently show more accurate data that match each others’, while mine doesn’t. I don’t receive special weather statements, and the temperatures and conditions are all different than theirs (and inaccurate). We all have iPhone 13s, all up to date, and all with the same settings. Problem persists when using manual and by location, as well as with precise location turned on/off. We all bought our phones around the same time this year, and this wasn’t an issue on my old phone. What is the matter and why is there no simple solution for this…?
