June against the rest of the year

June cloud at Alma averages 67% in NASA POWER's 2001 to 2020 record, 4 points clearer than its yearly mean. September is Alma's clearest month at 65%. By civil night times clear sky, June scores 2.1 hours at Alma, 11th of 12. Saguenay, 45 km away, averages the same 67%.

Civil night at Alma starts June at 6 h 39 min and reaches 6 h 24 min by June 30, 0.3 hours shorter. SWPC's 10 PM to 2 AM window is fully dark on every night. The sun never reaches 18 degrees down, so Alma gets no astronomical night in June.

June night by night

Activity in past Junes

Alma needs Kp 5 for the average oval edge to sit overhead. 73 of the 900 June days from 1996 to 2025 (8%) reached it in the GFZ Potsdam record, 9th of 12 months; storm days with Kp 5 or more made up 8%. Alma sits at 57.8 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
