Ahead of today's Shootout, the air temperature is 16 degrees C, while the track temperature is 19 degrees. It is cold and wet... very wet.
Indeed, the F3 Sprint earlier ended with no points being awarded as there was only one lap when the Safety Car wasn't on track.
This morning's weather follows the heavy rain of practice yesterday morning and the mixed conditions for qualifying in the afternoon.
The ever changing weather is causing a nightmare for the teams as they simply don't know which way it is going to go and therefore don't know how best to set up their cars, a situation further complicated by the fact that it looks as though Sunday will be dry.
As a result not only have we seen differences between the various teams but even between teammate, Mercedes, in particular, opting to give Russell a 'barn door' rear wing while teammate Hamilton had the much smaller version.
Due to the rain the start of Q1 is delayed. The rain subsequently stops and as the skies brighten track cleaners are sent out to push some of the water away.
At 12:18, race control confirms that Q1 will get underway at 12:35, even though conditions already appear to be fine.
Seven minutes before the green light the Mercedes pair head out of their garages.
Of course, another factor to consider here is the sheer length of the Spa track, for if you head out and then decide you're on the wrong tyres you've got just over four miles to go before you can do anything about it.
"It's very reminiscent of Q1, what with the sun shining," says Russell.
Track temperature has improved to 23 degrees but the air temperature remains at 16.
The lights go green and Hamilton leads the way, followed by Russell, Bottas, Zhou and Magnussen.
As more drivers head out all are on Inters, some new and some used.
Last out is Verstappen, who joins the track just ahead of Hamilton.
Hamilton gets things underway with a 2:02.297. Russell can only manage 5.067.
Magnussen pits at the end of his lap as Norris goes second ahead of Bottas, Zhou and Russell.
No sooner has Leclerc gone top than Piastri responds with a 1.311.

Verstappen goes quickest (55.200), ahead of Hamilton, Perez, Gasly and Leclerc.
Alonso and Albon head out but both have opted for Inters. Stroll perseveres with his slicks.
"We're committed to this, you've got to go," he is told. The Canadian clearly isn't happy.
"It's drying very fast," says Hamilton as Stroll goes off and into the barrier at Turn 9.
The session is red-flagged and will not restart, which is a disaster for his teammate, and the Williams pair, who had not posted times.
"We had to do what we had to do," says a clearly disappointed Albon, who admits surprise that Stroll opted for mediums as opposed to softs.

Verstappen has Sprint pole, ahead of Piastri, Leclerc, Norris, Gasly, Hamilton, Perez, Ocon and Russell.
Ricciardo is eleventh, ahead of Albon, Sargeant, Stroll, Albon, Tsunoda, Bottas, Magnussen, Zhou and Hulkenberg.
Ahead of this afternoon's Sprint one would very much like to be a fly on the wall of a coupe of the team debriefing offices, what with the Mercedes pair almost tripping up over one another and the disasters at Haas and Aston Martin.
