Rochester, MN (KROC AM News) - Not only was it dry in the Rochester area during June - it was also pretty warm.

In fact, numbers show it was the second-warmest June on record for the city.

The National Weather Service says the average temperature at Rochester International Airport was 73-degrees for the month of June. The only June that was hotter was 1933 (73.9°F).

The city experienced 90 degree days on nine days, about a third of the month. The NWS says multiple temperature records were set or tied during the first 11 days of the month and this contributed to a notable record - it was the city’s warmest first half of June ever.

It was also bone-dry the first half of the month.

No rain was recorded at the airport until June 17th. This helped jumpstart the drought the Rochester area has been dealing with in recent weeks. The city’s precipitation total for the month was 1.46 inches - making it the 7th driest June on record.
