The latest global climate summary for May was released by NOAA earlier this week. It shows that May 2019 was the 4th warmest May since global records started in 1880. The spring March through May period was the second warmest in the record after 2016. The year to date was the 3rd warmest. Note that North America is one of the few places where the temperatures were below the long term average, which just shows that what you are experiencing may or may not represent what is going on across the globe.
