Rio de Janeiro has been the warmest of my Ten Stations for all but two of the last 22 weeks. Its mean daily temperature above Pre-Industrial (my version) has dipped below the dreaded 2 degrees C and seems unlikely to rise again this meteorological year. Rio and the southern hemisphere are running cooler than the trendlines indicated at the end of August.

Below are a couple of graphs that present the Week 46 Mean Temperature in a different way. I have ranked the table from highest to the lowest temperature and added Durham Tees to the Ten Stations to put north-east England into what passes for a global context. I’ve given the ten stations “hemisphere colours” and Durham Tees the indicator colour for the goldilocks zone – not too hot and not too cold (between zero and 1.49°C above Pre-Industrial). You can clearly see the four stations “over the limit” in Week 46. (Mumbai is the week’s elephant in the room.)

Don’t be too complacent that the running average is below two degrees for all my stations as we near the end of the year. Robin at Seemorerocks offers an article by Anton Troianovski from The Independent about the melting permafrost in Siberia. Koltsovo is a long way from Siberia but is catching some of the heat. Climate Reanalyzer shows much of the Arctic Ocean to be over 4°C above average for much of the coming week, though mainland Siberia appears to be cooler.

Should one of my ten stations rise above two degrees next week, I think it will be Sydney. If I had a house, I’d put it on Buenos Aires being coolest. Again.
