Timeanddate.com has reported 92F for both the 30th and 31st of July. With the current temperature, I will wait until after midnight for the final market resolution

How are ties handled? Right now, the 13th and 15th both had highs of 91, but in the table view for the record high for this month, it just says the 13th. Maybe that is using decimals, and the 13th was hotter. Or would you just say they’re both 91, so they both win?

Seems like everyone prior to @aoeuidhtns assumed same integer = tied, and aoeui assumed otherwise.

Given that the 13th happened first, they might just be taking the first instance rather than tiebreaking based on hidden additional precision.

There is a summary table on the website linked in the description that reports a temperature high which appears to pick the earliest date in the case of ties. I assumed that the table is what would be used rather than manually checking each days numbers since the website was referenced for the resolution.

I have left both 13th and 15th as unresolved as I consider them tied and intend to pay off on both if 91F is not surpassed.

91F was hit on the 13th
