Hardly a freak weather event, the El Niño–Southern Oscillation (ENSO) has been recorded having a serious effect on the weather going back to Inca times, so it's got nothing to do with AGW, either. It's what gave us the extraordinarily hot and dry weather for most of this year. Interestingly, it was predicted to peak in the Autumn and possibly result in 2024 being the hottest year on record, but now it looks like this strong El Niño is going to decline unusually rapidly, and things could be back to normal by April.
