12.0c...Cheer’s...to start, then the 2nd half ☔

[summer blizzard]

Stick me at 10.7C, bang on the 30 year average.

Although i do not enter the precipitation forecast i expect an extremely wet month with 100mm+.

[I remember Atlantic 252]

wet from 14th, dry before then, 10.1C

[DiagonalRedLine]

Hoping for a chilly one this year. Don’t mind the first part being warm and Summery. Second half love to be very below average with some frosts and wintry weather. CET guess: 7.7*C.

[CheesepuffScott]

9.9C and 117mm.

A few warm days to start, turning wet and cool afterwards, and one or two storms. 

[Weather26]

Let's go for a cooler than last year-i.e 10.4C and 88mm Please

[Leo97t]

10C and 80mm

[damianslaw]

Will wait until end of the month before posting my guess. Notable how many of the warmest Octobers on record have occurred in the past 20 years or so. We've had a real mix of Octobers in recent years, but one notable aspect has been the tendency for very mild ends, some very mild Halloweens indeed. I like October to trend colder throughout, with the first air frost by the third week, and a spell of high pressure frosty nights, and foggy mornings before the month is out, with the traditional stormy end and the first smattering of shortlived white stuff on the high tops.- a shot of arctic air always welcomed.

More often than not, October can see the atlantic wage supreme with mild murky dank wet westerly/southwesterly airstreams - think 2013, not a fan of such months. I would be happy with a Oct like 2008, 2010 and 2012 with all brought a potent northerly clean blast.

As theres not been a 10cet as I`ve had a quick glance,I`ll go for that every month since august has gone below what I went for so I`ll go a touch below average this time.

There will be an indian summer snap.
