Cape Lopatka - the southern edge of Kamchatka Peninsula, has a 2.9°C avg high in May. That is lower than March in Landsort, a similar peninsular head east of me in March and ice days can definitely occur until late that month there. In addition, June is cooler than April here, so wouldn't completely rule out ice days until June 4-5 sometime at Cape Lopatka. Could you find any place in the world that could match the stunning 61° it has in peak sun angle by the shift of May and June and still turn it into an ice day? I really struggle to think of one. It could happen in Inukjuak in early June so say 54° only there. I think Nakhodka could get there until the end of first week of April, so that would be 53°, so mighty close to Inukjuak but nowhere near Cape Lopatka. To find adequate seasonal lag anywhere to replicate that will be mighty difficult, but would be interesting to learn some amazing sun angles for ice days and even frosts! The most impressive sun angle for a frost where I've been is probably that we got this stunning -4°C night low on May 9 on a day that peaked at a 48° angle - enough to get sunburn. Ice day though, well, Norrköping hasn't recorded one in April during my lifetime, but probably around 20 March sometime and that would be 31°, so nowhere near Cape Lopatka for sure  |

Rochester’s latest recorded ice day is April 25.
Our sun angle is 60 degrees then. So close...
Not sea level, but I don’t think ~150 m makes a big difference.

Wonder if there are places such as Houghton, Michigan cooled by Lake Superior that could even beat that?  Could you look Houghton up since you're well-immersed in NOAA's search functions? |

Caribou, Maine, Duluth, MN, Buffalo, NY, and Minneapolis, MN are all at 60. Somewhere in the eastern US probably is higher but farther south the last ice day is too early and father north the sun angle is too low... |

It's a little sticky that yeah, I wonder whether some shielded maritime place in Eastern Canada could perhaps even beat that? I could perhaps see Kentville in Nova Scotia being located towards the mainland by cold water get one really late. Sadly there would be no way to get data for Cape Lopatka, but it appears as though it and Houghton are extremely good candidates for winning. Having said that, with Cape Lopatka being at 50°N it gets sun angles of almost 63° and it being that freezehole it wouldn't surprise me if it got an ice day above 62°... Nah, Kentville appears really warm in May, so it might have to be inland somewhere near a lake. Truly astonishing how those things are even possible though! |

Vow, The climate of Cape Lopatka is a complete disaster. Even Eureka, Nunavut has a higher record high.

Yeah pretty epic those places... how many places below the tropic of Cancer has had an ice day?

I found daily climate data for Cape Lopatka. What a terrible climate. Their latest ice day is May 14th, 2000. Max -0.5 min -1.9. May 26th, 1980 was +0.4/-1.3, very close. Their climate must be extremely consistent compared to most cold places. The record low is only -21 and some of the records are only 5C from normal (like May). Current data is on Ogimet, the station is #32213. Older data is on this Russian climate site. cdiac.ess-dive.lbl.gov/ftp/russia_daily/Russia_518_inventory.pdfGo to here, cdiac.ess-dive.lbl.gov/ftp/russia_daily/, and there's a text file with daily data for each site. (Yes, Ojmjakon and Verkhojansk are on there) Where's GlacierX when you need them? They probably could find the peak sun angle for an ice day in Canada at least. Edit: What's the sun angle there on May 14th? |

Truly astonishing how those things are even possible though! if a cold air mass moves from high latitudes fast, a high sun angle won't prevent extreme cold. We had a cold air mass with -12°C 850 hPa temperatures two years ago in early April, high sun angle meant a bigger diurnal range: still an ice day. Wouldn't be surprised if Newfoundland had some very late season ice days, dunno if it'd be as high as those mentioned earlier. |

High of 6°C, prior air and sun was too strong for for an ice day. |

Our latest ice day was 2nd March 2018, with a sun angle of 31.6°.
