Kronan kan du titta vad Umeås årliga min temp är? Baba tror att han lever i en 5b/6a hardiness zone? går la bra. umeå flygplats 1981-2017: -27.6C (hardiness zone 5a) The fuck? That's wildly different from hurvarvadret. 25 vs 27.6 for the same 45 year period |

Tack!
Umeå centrum är i vilket fall som helst inte 6a.

Kronan kan du titta vad Umeås årliga min temp är? Baba tror att han lever i en 5b/6a hardiness zone? Mod-approved foreignor message  I'd guess -28°C? I could look up 2002-2017 (so far) though. EDIT: Oh, how close were I? On Hurvarvädret it was -25'C :/ |

On Hurvarvädret it was -25'C :/ Sounds quite reasonable to be fair. Coastal moderation and all that. Tempted to look Piteå up to see the difference. Too tired atm tho  |

Tack! Umeå centrum är i vilket fall som helst inte 6a. We used different sources. His got wildly different results from mine. Both are SMHI sources so I wasn't picking a source I thought would give me warmer results exactly. I get the point of leaving UHI out of climate averages, but for hardiness I think it's completely fair to account for UHI since it's about what plants would survive there, and you would have better chances of growing delicate plants in the city compared to on the airfield. For 1988-2016 the airport was super close to 6a with the SMHI source I used so I figured the actual city would manage 6a without a sweat for that period, and for 81-16 it was -25, and I'm pretty sure the airport will be at the very least a couple of degrees colder than the city on the coldest day of the year. The university station would thus manage 6a for 81-16 as well of large parts of the city, and some parts I think would fail 6a for 81-16. This was based on my source. Still, I have no doubt the actual centermost part of Umeå would manage 6a or even 6b easily for 81-16 since the ground is heated, and the coldest days are always wind free. But I wasn't counting that part of the town earlier. |

går la bra. umeå flygplats 1981-2017: -27.6C (hardiness zone 5a) The fuck? That's wildly different from hurvarvadret. 25 vs 27.6 for the same 45 year period nah, they compare very well to hurvarvädret this is the data i got 1981 -29,9 1982 -28,6 1983 -27,9 1984 -26,6 1985 -32,1 1986 -29,8 1987 -34,9 1988 -25,1 1989 -27,8 1990 -26 1991 -21,9 1992 -21 1993 -22,3 1994 -32,6 1995 -25 1996 -25,5 1997 -23,2 1998 -27,1 1999 -33,3 2000 -27 2001 -29,9 2002 -30,4 2003 -35,1 2004 -26,3 2005 -28,7 2006 -28,3 2007 -27,3 2008 -18,3 2009 -28,9 2010 -32,5 2011 -28,7 2012 -30,9 2013 -28,3 2014 -23,2 2015 -19,6 2016 -28 2017 -26 mean: -27,5135135135 |

The coastal moderation has no effect as the Gulf of Bothnia freezes over every damn year. Even down there every year? Boke. Holmön looks too mild for me for it to be such a 100 % certainty, also if the entire area turns inland over winter, then those normals either side are just astonishing  Besides, do you know whether the entire Baltic Sea froze in 1942? Seems like that judging by those sick March record lows recorded in a location like Landsort (Utö of my coastal area) that year! |

Seems like that judging by those sick March record lows recorded in a location like Landsort (Utö of my coastal area) that year! The immediate coast of Holmön and Umeå are always frozen (except 2015) but only like once in a decade the whole sea is frozen. This is mid February. Still, in January and December, during a lot of the time for potential annual minimums, the sea is completely open. |

I watched peak ice maps since 2002 and every single year. Roughly north of the Vaasa - Örnsköldsvik line there's guaranteed ice. Most years you can drive from Umeå to Jakobstad with a car. The last time the entire Baltic Sea froze over was 1987. |

Still impressive how those February temps are kept in check as far north as in Haparanda then, merely the fact that there's a difference between Haparanda and Överkalix that month when it's always ice. Never even took that into consideration dammit, just thought it was always the coast from Skellefteå and up north but not always the entirety thereof. 1987, oh that must've been fairly brief since temps recovered big-time in February in areas as far inland as Örebro? I remember remarkable ice formation 2003 when I skiied off the shore of Nyköping's inlet, but I don't recall how big ice covers there were in 09-10 and 10-11, do you? |

The ice is only that extensive far past the majority of the record low capable season, December is 100% moderated, in January there's usually either no ice or only coastal ice. In February it's either coastal ice or an ice bridge between Holmön and Umeå, but with open sea all around. Only like once a decade can you walk from Umeå to Finland before March. Actually, 100% ice free is more common than 100% frozen in February. |

Sorry Baba, but I think your observations are quite wrong.
Even from Helsinki it's occationally possible to walk to Tallinn, and you have already walked on ice this season. I might not be able to walk across the river during the whole winter.

I don't recall Nyköpings' river freezing, probably because of all the artificial waterfalls and stuff. It part-freezes and in narrow spots, but never fully.

Just look at zoom.earth. 15th of February is never frozen enough for you to walk over, not since 2007 at least. In 2011 you could on the 20th but not the 14th of February. In 2009 it was really odd. The 14th and 15th were like 90% ice free, and then the 16th saw a full ice cover. Really odd. Then on the 23rd it was gone again.
