July has arrived, so it is a perfect time to look back and summarize June 2024 and the 2023/2024 snowfall season, which ended on June 30. If I were to use adjectives to summarize June 2024’s weather conditions on the summit, they would be – warm, moist, and windy. To find out why, let’s look back at some of the stats for June 2024:

Our average temperature for June 2024 was 48.2°F (9°C), which is 2.7°F above the 1991-2020 30-year normal for our station. The average temperature of 48.2°F ties it with 1967 for the sixth warmest June in our dataset. Our warmest temperature recorded in June 2024 was 70°F (21.1°C) on June 19. Our coldest temperature recorded in June 2024 was 27°F (-2.8°C) on June 28.

In terms of winds, our average for June 2024 was 28.3 mph, which was 1.5 mph above the 1991-2020 30-year normal for our location. Our highest gust recorded for June 2024 was 96 mph from the southwest on June 23. June 2024 had 11 days with gusts of 73 mph or greater.

As for our weather during June 2024, we averaged 32% of the possible sunshine. The summit had 0 days that were noted as clear or mostly clear, and there were 8 partly sunny days. The remaining 22 days were filed under mostly cloudy, cloudy, or obscured (fog). We had 25 days with at least some amount of fog recorded during a 24-hour period. We had 23 days with rain/drizzle and two days with hail/sleet.

In terms of total liquid-equivalent precipitation (which reflects the liquid collected from rain and by melting the freezing and frozen precipitation types collected after measuring their depth) during June 2024, the summit of Mt Washington received 8.12 inches, which was 0.47 inches below the 1991-2020 30-year normal for our location. The summit received 0.2 inches of hail/sleet, which was 1.1 inches below our location’s 1991-2020 30-year normal.

For Mt. Washington, our precipitation/snowfall season went from July 1, 2023 until June 30, 2024. In terms of total liquid-equivalent precipitation (which, again, reflects the liquid collected from rain and by melting the freezing and frozen precipitation types collected after measuring their depth) during the 2023/2024 season, the summit of Mt Washington received 114.54 inches, which was 23.31 inches above the 1991-2020 30-year normal for our location. During the 2023/24 season, the summit received 304.4 inches of snow/graupel/sleet/snow pellets/hail, 22.6 inches above our location’s 1991-2020 30-year normal.
