ERA5 hourly data on single levels from 1940 to present

I am using this 2m hourly temperature data in the context of Peru. I am interested in using the minimum temperature values during the day. I find that the minimum temperature occurs during 11am, 12pm during the day. Moreover, the temperature keeps falling untill 12pm, and then continues to rise. This occurs pretty much consistently. I had a prior that the minimum temperature would occur sometime during 5am, 6am in the day and would keep rising thereafter, but in this data it seems that the minimum is happening at around 11 am/ 12 pm. Anyone has seen this issue before, or knows what could be the possible reason behind this?

You should consider that the ERA5 time is UTC based: Time reference from ERA5 reanalysis

Thanks! It skipped my mind, this explains the data the pattern then.
