Oslo Blindern's average high in January so far is -0.3C. It's totally possible they wouldn't have ice day averages when the new normals comes out.

Re. ice day averages, I've compared what we have so far of 2011-20 (going into the new recording period) to 1981-90 (going out):

1981 20 - 0 2011
1982 10 - 1 2012
1983 6 - 13 2013
1984 5 - 0 2014
1985 21 - 1 2015
1986 25 - 0 2016
1987 10 - 0 2017 (up to 12th February)

The late 1980s was actually really mild, but the rest of the 2010s still has 82 ice days to catch up on lol

Oh, so it's that close.

Here in Trondheim we did have avg high just above freezing (0.1C in January) using 1961-90, so the high will be well above in the new normal.

Okay........although I personally don't know how to physically post the latest climate normals for this 'incomplete' 26 year period of record from 1991 to 2016, I will manually write out in short form what this yet to be seen climate normals for Indianapolis, Indiana, based on calculating the data myself, I have discovered that the average annual temperature for Indianapolis for the above stated period is now at 53.6 Degrees Fahrenheit, as for average annual precipitation for the same period, Indianapolis averages 43.24 inches of annual precipitation, this continues the present and recent uptick in both average annual temperatures and average annual precipitation for the circle city, for a reference the average annual mean temperature for the 1981-2010 period is 53.2 Degrees Fahrenheit and the 1981-2010 average annual precipitation for the city is 42.44 inches.

I guess it depends on what this winter and the next three serve up. The 30 year snowfall, for KNYC at least seems to bounce around in the 20's. The summer temperatures for KNYC have actually dropped from both the 1931-60 and 1941-70 maximum means of 77.5 to 76.5.

I submit we should be using a 50 or 60 year base anyway since even these movements have too much "noise" from exceptional summers or winters. The summer temperatures dropped when the 1950's run of hot summers left the averages.

For four years in a row, 1952-55, and then again in 1957 NYC went to or over 100. That's five summers. After that our 100+ numbers occurred in 1966, a close call with a 99 in 1973, 1977, 1980, a close call with a 99 in 1983, 1987 and 1988, 1991, 1993, 1995, 1999, 2001, and then another three in a row in 2010-12.

Snowfall has similarly gyrated, with notably snowless years in 1949-55, 1962-3, 1967-8, 1970-77 (one event of note on New Year's Day 1971 and that's it), 1984-1986, 1988-92, 1997-very end of 2000, 2001-2, and 2011-12. Jackpot snow years were 1960-1, 1977-8 and 1978-9, 1995-6, 2002-3 through 2005-6, 2009-10 and 2010-11 (opposite ENSO states), and 2013-4 and 2014-5.

So 30 year means can be quite distorted.

We should use 60 year means imo, that way we encompass 2 full cycles of ocean phases for an accurate average.

Warmer year round, specially in the early summer (April-May) and November. Winters I don't think that they will surpass +0.5ºC from the actual average.

Also with increased rainfall. All of this zone had a couple of years in the last 10 which were amongst the top 5 of the most humid since 1980. Also probably sunnier, but just slightly more.

I don't have any expectations. I remember the occasional extreme-weather day/week and pretty much forget all the other days/weeks. And, of course, the hot days are remembered as being hotter than they were and the cold days are remembered as being colder.

I can tell you this about Canada's 2020 climate normals -- they're screwed. What I mean is that severe cutbacks in 1995 and again in 2001 has severely cripple data collection. Add in the elimination of quality control checks in 2007 and outsourcing of airport weather data to NavCanda (the company tasked with running the airports, and not as interested in data collecting), and you have a recipe for not having very many normals. The new airport stations have different WMO numbers so technically they can't be merged in with the old data to get a climate normal. It took several years past 2010 for Environment Canada to release 1981-2010 data, and since the new government is hell bent on shifting money away from climate monitoring into "climate change research grants," it'll probably be 2025 before the data is released if at all.

As you know, Sydney CBD is very maritime influenced. The Australian east coast is the most warmest east coast in the world anyway (or at least, compared to eastern China and and eastern USA).

Camden, a southeast Sydney suburb, went down to -2C last year.
