Highest temperature in Singapore on September 9?

What this question means

Two days after the 7 September question on the same city, and the distribution is nearly identical: 33°C at 66%, with 32°C at 27% and 34°C at 6%.

That similarity is the point worth noticing. When two forecasts for different dates in the same place look the same, you are not looking at a weather forecast so much as a climate one — the crowd is pricing what Singapore in September typically does, because there is little else to distinguish one day from another.

The small differences are still readable. This one has more weight on 32°C and less on 34°C than its counterpart, tilting very slightly cooler.

Distributions like these are useful practice precisely because they are boring. There is no drama, no narrative, no argument about definitions — just a well-understood system, a clear measurement, and a crowd whose confidence is proportionate to how predictable the thing actually is. Most questions would benefit from being read that way.
