Here’s today’s Final Jeopardy (in the category Science Records) for Tuesday, October 7, 2025 (Season 42, Game 22):
It was introduced in 1992 & the record 43.3 was set in the high Andes, where stratospheric ozone levels are naturally low
(correct response beneath the contestants)
Today’s Jeopardy! contestants:
Claudine Lewis, an elementary school teacher originally from St. Louis, Missouri
|
Slade Gilmer, a paint quality team member originally from Russellville, Alabama
|
TJ Fisher, a marketing specialist from San Francisco, California (3-day total: $59,924)
|
Andy’s Pregame Thoughts:
With just over a month remaining until the postseason cutoff, even the three wins from TJ Fisher are looking good for Tournament of Champions qualification. But nothing is guaranteed (barring death or personal misconduct, of course) until he reaches five victories, and certainly both Slade Gilmer and Claudine Lewis will want to end TJ’s streak at 3 games. That being said, TJ’s buzzer % (per the boxscores) dropped yesterday into the high 60% range from the 70s and 80s that he was in last week. If the buzzer % stays in the 60s, that would prove to be good news for today’s challengers.
Continuing on from yesterday’s editorial, with one thing I haven’t posted yet of that would be within the realm of the show to potentially do, at least in order to curtail my accusations of unfairness between Second Chance and Champions Wildcard: take one of the Second Chance weeks and just invite “fan favorite” champions who didn’t qualify for Champions Wildcard to play for a spot in the Champions Wildcard event. That way, you at least have a potential pathway for those 1-time champions to continue their journey without being in a state of eternal Jeopardy! purgatory.

Correct response: What is the UV index (ultraviolet index)?
More information about Final Jeopardy:
(The following write-up is original content and is copyright 2025 The Jeopardy! Fan. It may not be copied without linked attribution back to this page.)
Used to measure the strength of ultraviolet radiation reaching the Earth’s surface, and therefore the likelihood of sunburned skin, the ultraviolet index was developed in 1992 as a linear 0-to-10 scale, with 0 being zero UV radiation (as would usually occur at night) and 10 corresponding to midday summer sunlight in the tropics with a clear sky and normal ozone levels. Since the index’s adoption, though, other environmental factors (such as ozone depletion, higher albedo levels due to increased reflectivity off water, or high altitudes) have led to readings higher than 10, with the record reading being 43.3.
The key to this clue, in my opinion, are the words “ozone” and “low”; from there, remembering environmental science classes should hopefully get viewers and players to the UV index. It’s also never a bad idea to remind the home viewers about environmental impacts, in my opinion.

Game Recap & Tonight’s Game Stats:
Looking to find out who won Jeopardy! today? Here’s the Tuesday, October 7, 2025 Jeopardy! by the numbers, along with a recap:
Jeopardy! Round:

Today’s interviews:
Claudine won the first “Deathly Double” contest from the “Inside Jeopardy” podcast.
Slade makes sure there are no defects in a car’s paint job—but he’s colorblind.

Double Jeopardy! Round:
(Categories: The 16th Century; Words From Around The World; U.S. Cities; The Grammy For Best Comedy Album; Famous Women; Isn’t It Romantic?)
TJ was definitely “once bitten, twice shy” in this round; he lost $3,500 on DD2; he bet just $100 on DD3. However, even though he got it correct, the fact that neither challenger could find it was good enough to make sure TJ had a runaway going into Final Jeopardy.

Slade 12 correct 2 incorrect
Total number of unplayed clues this season: 3 (0 today).

Andy’s Thoughts:
- If the postseason is structured identically to 2025, then TJ is guaranteed ToC qualification even with 4 wins; there aren’t enough games left in the qualifying period for enough people to knock him out of the tournament.

I’m surprised Andy didn’t mention that the UV Index was developed in Canada.
TJ is such an interesting player. He is so dominant in regular play, but his betting and FJ play leave him vulnerable for the postseason. He’s been a lot of fun to watch. He has a lot more passion for the game than some champions.
Seeing “High Andes”, I was thinking about telescopes and astronomy, but no astronomical records came to mind. 🙁
Upon reading today’s final clue, I predicted a triple stumper. This was a pretty obscure fact that few people are probably aware of. My feeling was this might be more appropriate for a final in tournament play of some sort. Of course, that’s just my opinion so others may disagree with me.
I did think that it probably did have something to do with “air quality”, like amount of oxygen, or amount of atmospheric radiation, or whatever, but could not think of the UV index — partially because I thought that dated farther back than 1992.
I kept yammering about ozone and couldn’t even get an answer out. Oh well.
