Here; during my lifetime I'd say anything between 20/11 and 27/15 is entirely possible for the warmest month, beneath 20°C in both July and August could theoretically happen but it hasn't for many decades. In Örebro that'd be more like 20/9 to 27/14; for Stockholm's UHI rather 20/11 to 27/17.
Based upon an inland station (Linköping) of July 1901; I'd venture July probably was 28/15 here back then though, but everything has to be perfectly set up for that 1 in 100 years month.
What about your locations? Is it a small or high possible range?

Theoretically we could get 19/11 or 29/17, if the 30 day period lined up with a calendar month.
Hottest July had an average high of 28.2c. The coolest July had an average high of 19.8c.
Statistically in a 5 year period, the coldest July will be 22/13 and the warmest 25/15.

July's range could be the following:
Warmest: 25/15 - July 2006 was 24/14
Coldest: 15/8

For NYC:
July 2010 ~ 91/75°F (33/24°C)
July 1969 ~ 80/67°F (27/19°C)
30 year average is 86/71°F (30/22°C), squarely in the middle of that range.

July average high
-The coldest was 73.2 (22.9 C) in 1884
-The hottest was 88.1 (31.2 C) in 1952
July average low
-The coldest was 55.5 (13.1 C) in 1965
-The hottest was 69.0 (20.6 C) in 1921
If those lined up, we could range from a 73/55 July to an 88/69 July (23/13 to 31/21 C).

Here are the coldest and warmest calendar Julys recorded in Paree:
Coldest: 20.8/11.0°C
Warmest: 30.4/19.3°C
So anything from a proper summer month to a subarctic wankfest is possible. That's why having a warmer than normal summer is crucial. A big difference with Nice.

April is normally the warmest month here. Going by wunderground.com's data for DMK going back to 1996 it looks as though the coolest April had a mean low / high of 25 / 33 C and the warmest had 28 / 37 C. The average is 26.3 C / 35.7 C.

The warmest month of every year since 2000 in Observatory Hill. Years with an asterisk had a month or even two months with warmer max temps, but a lower mean.
2018 20.1/27.8 J
2017 21.6/29.6 J
2016 20.6/28.2 F
2015 20.4/27.5 J
2014 19.8/26.9 J
2013 20.5/27.6 J
2012 19.6/26.1 J
2011 21.1/28.4 F
2010 21.2/27.4 F*
2009 19.9/27.6 J
2008 20.3/26.0 J
2007 20.6/26.0 F*
2006 20.3/27.8 F
2005 18.9/28.6 D
2004 20.3/28.1 F
2003 20.6/27.1 F*
2002 19.8/27.2 J
2001 20.6/27.3 F
2000 19.6/27.5 F & 19.5/27.6 D
Not much of a range really.

Warmest month on average or warmest of the year? If our July were 18/10 one year, August or June would be warmer.

Then I think 18.5'C is the lowest average high and the highest about 25.5'C for the airport. 20'C mean is about the highest and I guess like 14'C the lowest.

In 1962 the warmest month in Kronoby was July with a 13.1C mean (17.6C/8.5C). Of course that was a long time ago, and since 1990 the coldest summer month highest mean has been 14.6C. |

For February, 16.8°C/30.3°C was recorded in 1997 and 12.6°C/23.3°C in 2005, but 11.8°C was the average minimum in 1987.
So I'd say the very extreme ranges could be from about 11/22 to 17/31.

Wasn't August probably warmer than July 1962? Lol, since 1901 Umeå's coldest was 12.1'C, one year after the records started. August or June must've been warmer than that though. Either way a 12.1'C July is simply not possible anymore. |

For Madison, Wisconsin: July average is 21.8C/71.3F, records are +42 and +2C (107 and 36F)
Coldest was 18.7 Hottest 26.6 (66 to 80F)
Lowest mean: 18.7C/66F in 2009. It was consistently average or below average, only 3 days above average. I wasn't interested in weather much then, but I don't remember any unusual weather. The warmest day of the month was 28C/82F which is the normal high for the month. The coldest it got was 8C/47F, which is a normal monthly low for July. Average max/min is 24.3/13.1 (75.8/55.5F)
Highest mean: 26.6C/79.8F in 1901. Second highest was July 2012 at 26.3C/79.4F. 2012 was a warm year and had an extremely warm March, warm Spring, and very warm and dry June. I was working outside that summer and remember it being too hot most days.
June had an average of 22.0C/71.6F, daily average was 29.2/14.8 (84.6/58.6) but only 8mm/0.31" precipitation (Driest June on record).
July had an average of 26.3C/79.8F, averages were 32.9/19.8 (91.3/67.6). The hottest was 40C/104F, coldest 13C/55F. Only one day was below normal all month. It didn't rain until July 18th, so there was a 6-week period with barely any rain in the wettest time of the year. Normally there should have been about 150mm/6".
Fireworks were cancelled for the 4th of July for the first time I remember, too risky with the drought. The 4th had a high of 39C/102F and a low of just 27C/81F, which is the normal high that time of year. July 5th hit 40C/104F and two more days that month reached 38C/100F. The grass was brown most of the summer and some trees lost their leaves in July due to the drought. Rivers and lakes were also very low.

Our warmest month can either be July or August. Usually July is a stable month for which real summer-like condition are practically assured all over the month, while August is a little bit more variable (in particular the second half) and sometimes managed to surpass July because of some really intense and long-lasting heatwaves. Looking at the weather records of the closest weather station to my place [1], which cover the period 1991-2017, - The warmest month was August 2003 (30.4/20.3°C) closely followed by July 2015 (29.4/20.4°C)
- The coldest values for the warmest month of that year was July 1996 (24.0/15.8°C), the temperature measured in the following month were just a couple of decimal colder.
On average our warmest month is July with an average high/low of 26.1/17.4°C, while August is just slightly cooler with 25.7/17.0°C, and the most of years are actually closer to these averages than to the extremes. |

Find it very interesting how stable the record low warmest month values are for an inland climate in the mountains like that. I've noticed most of climates up here have an 8°C (or thereabouts) amplitude in terms of avg high between the coldest and warmest months. Granted, the sun is weaker here, but almost all of this country is heavily influenced by the sea. Do you have any specific idea of how come your closest station is so "maritime" and stable as it is in spite of its location?  That being said, it would've been interesting to see how one of those really cool summers in the 1961-1990 reference period up in Northern Europe would've affected your stable station's averages. |

Despite of our position, during the summer our weather mostly depends on the same high-pressure systems as the rest of Italy, like the Azores High or hot air masses from Africa. Cooler and more humid air masses are less likely to reach us than places on the other side of the Alps (but they are still more likely to reach N. Italy than the Peninsular part). All the cooler than average summer months in our records are actually related to rainy months too, in which the humid air and cooler air masses managed to reach us more often than usual. During those rainy days the temperature can be much lower than the average (the high can also go down to 19/20°C), but the rest of those months is not so far from the average. |
