Similar to the ice day sun angle thread but this time with snow cover. I wonder if there has ever been a 60° or even 70° sun angle with sea level snow.

According to Port Au Francais' wiki page, snowfall is possible even in the summer. At 49°N they could possibly have snow cover at 64° sun angles. Combined with the ozone hole I think that might take the cake for sea level UV index.
Unless anyone can find something better that is

Unless anyone can find something better that is I think it looks extremely unlikely given the moderate record lows and if it came then it'd probably be a dusting of sleet and not proper snow cover if you know what I mean? My guess would be Yuzhno-Kurilsk in early June; lots of snow remaining from a cold winter and unable to shake it off. |

When does the snow melt off in Hokkaido, such as Aomori? Is this for snow cover lasting through the winter, or just lying snow from a random snowstorm? Latest constant snow cover in low-elevation US is sometime in May. But probably not late May. There's definitely been a 60 degree sun angle at low elevations. www.weather.gov/arx/may27291947snowThese places aren't at sea level but there's places under 300m/1000' in there. And definitely snow cover. Also, it snowed in summer 1816 in the US: en.wikipedia.org/wiki/Year_Without_a_Summer |

Happy Goose Valley had snow cover in early June just a couple of years ago. Can probably creep a bit south from that in extreme cases.

I had snow cover around sunset Saturday; noon sun angle was 64° but snow fell when the sun was almost down (and covered with clouds). And melted it overnight. Does that count? |

London had snow on the ground as late as 6 April, with a sun angle of 45.3°.

Credits to alex992  Most of Iowa's northern half had snowfall - even at a modest enough just over 1000' elevation - less than a week before June 1947 That time of year is 2° short of summer solstice max sun angle (+21° sun declination), at 41-43 °N means around 68-70° solar noon sun angle - similar to equator's peak sun angle for May 27-29 |
