Well, I think I overdid (55°C has never been reached)
For sure, an HI of 49°C has been reached so many times during heat waves:
on August 14th, 2008;
on August 19th, 20th, 21st, 22nd, 27th, 2009;
on August 21st, 23rd, 24th, 2011;
An example: Weather History for Rimini, Italy | Weather Underground

I also remember a index of 51°C in August 2011, but unfortunately the hourly airport data haven't decimals, so they report 31°C and 100% ur, but 31°C may actually be 31,4°C, easily reaching an HI of 50-51°C.

I can't find older hourly data but we had 38,9°C on August 23, 2000 with an average daily humidity of 73%, and 37°C with an average humidity of 75% on July 26th, 1983. I think an Hi around 50-52°C is not unlikely for those two days.
