I know some people on here like to label things as fictional just because they don't fully understand them, but the El Nino thing isn't just something that the golf people in TV made up out of thin air. It's been widely reported all over Florida this year:

Even 8 years ago it was identified as a cause of poor golf conditions by the USGA:

I'm not saying that the only reason was El Nino, that's obvious. But it likely had to do with putting these poorly managed courses over the tipping point at this exact time.
