Men who shouldn't are walking topless in public, all those who a week ago were complaining about the cold and rain are now moaning about the heat and humidity, and the word Tim is featuring strongly in sporting headlines. It must be summer.
But there's an upside to late June. All around the land marquees are being erected, barrels of real ale are being rolled into them, and all manner of jazz bands are climbing up onto stages to share with us their bonhomie and good music.
This weekend we have two at opposite ends of the Midlands.
Head south and you can take in the 20th International Oliver Cromwell Jazz Festival at Upton upon Severn in Worcestershire, which runs from Friday to Sunday.
This festival offers a wide range of styles but its real strength lies in the trad, Dixie and New Orleans areas and features the celebrated veterans along with the fresh faces.
Among the highlights are:
* Friday: Kenny Ball & His Jazzmen, King Pleasure & The Biscuit Boys, the Bia Mandag Jazz Band from Denmark, Lamarotte from Holland, and Rod Chambers' Louisiana Joymakers.
* Saturday: Mr Acker Bilk & His Paramount Jazz Band, the Merseysippi Jazz Band with Clinton Ford, Bob Kerr & His Whoopee Band, and the Hanna Richardson Trio from the USA.
* Sunday: the Pasadena Roof Orchestra, the Blue Magnolia Jass Orchestra, and Christine Tyrell with Phil Mason's New Orleans All Stars.
The Oliver Cromwell Jazz Festival takes place down by the riverside at Upton upon Severn, in three giant marquees named Fats' Place, Oliver's and Satchmo's and in the Jazz Garden and Tommy's Bar, as well as in some pubs in the town.
There are weekend tickets or you can just go for one day. There's camping too. More information from Jazz Festival Office, 18 Riverside Close, Upton upon Severn, Worcs WR8 0JN. Tel 01684 593254 / credit cards 01684 594200 . Email firstname.lastname@example.org lnternet www.uptonjazz
Meanwhile, up north, is the festival which sums up all its attractions in its title: the Lichfield Real Ale, Jazz & Blues Festival. This is a slightly younger do - 16 years old to Upton's 20 - and it's younger in spirit and musical leanings, too.
Much younger in the case of the Netherstowe Big Band, a lively school band with an age range between 14 and 17 which will be appearing tomorrow night with special guest, trombonist Dennis Rollins.
Friday night is blues night with The Sleaze Brothers, and it's back to jazz on Saturday and Sunday with a programme running from noon till closing time and each band playing two sets so you can go for the afternoon or the evening and catch everything.
Saturday's highlights include guitarist Jonny Phillips and Oriole, a band with Brazilian leanings and high-profile players in drummer Seb Rochford and saxophonist Ingrid Laubrock, the Annie Whitehead Quartet, Soothsayers and Elements.
Elements is led by Rod Mason, a giant of the saxophonist with a blistering Breckerish power who can be tempted to end his session by blowing two saxes at once (the spirit of Roland Kirk lives on).
Sunday highlights include the Jonathan Gee Trio, the Deirdre Cartwright Group and the Walsall Jazz Orchestra. Among many good big bands in the region the Walsall Jazz Orchestra has a trump card in the form of pianist Tim Amman. His compositions stand tall beside those of Chick Corea, Pat Metheny and Jaco Pastorius. Great stuff.
And before all that, tonight the Lichfield festival opens with The British Kings Of Swing, with Alan Barnes on saxes, Roy Sainsbury on guitar and Roy Williams on trombone and a rock-solid Midland rhythm section and BBC Big Band vocalist Lee Gibson.

Also this week, the band that leaves spaces in the music but not in its name, Therogerinnisszone is at the Jam House on Tuesday, from 9.30pm.
It's an opportunity to hear what Birmingham bassman Roger Inniss (it's his zone, geddit?) has been getting together for his debut album, now out.
The Zone is completed by Carlton Romillie on saxophone, Chris Storr on trumpet and Rod Youngs on drums.
There's more about him and the new disc on www.therogerinnisszone.co.uk
