June in Juneau typically has the fewest number of days with measurable precipitation (0.01" or more) of any month in the year (average 16 days). However, this year there were 23 days with measurable precipitation, which ties with 1963 as the third greatest for any June. Rainfall was above normal at 3.86" ( 98.0mm), which is 119% of normal. However, many June months have had a greater total. Climate observations have been made at the Juneau airport since the late 1930s.
Fairbanks Airport received 1.03" (26.2mm) of rain on June 11. This not only broke the previous record for the date 0.96" (24.4mm) set in 2016, but it is also the earliest date in the summer to have an inch or more of rainfall. The previous earliest one-inch day was June 12, 1955.
The temperature at the Haines Airport topped out at 83°F (28°C) on June 8. This just exceeds the record for the date of 82°F (28°F) set 1946. Climate observations have been made at Haines, with some breaks, since the mid-1920s.
The high temperature at Fort Greely near Delta Junction on June 9 was 88°F (31°C). This easily breaks the record for the date of 83°F (28°C) set in 1957.

The only earlier occurrence in more than a century of climate observations occurred May 28, 1947, when the temperature also reached 90°F (32°C).
The average temperature at Nome for the week of June 4-10 of 61.8°F (16.6°C) is easily the warmest week of record so early in the summer in the Gold Rush City.

Like much of the Interior, June 9 was a scorching day at Northway. The high temperature of 89°F (32°C) smashed the previous record high for the date of 81°F (27°C) set in 1946 but is also the warmest temperature so early in the summer and ties for the third highest temperature on record at Northway. The highest temperature of record is 91°F (33°C) set June 15, 1969. Climate observations have been made at Northway since late 1942.
