\"Windsor,<\/a><\/p>\n

Jan, 12, 1939, The Northern Star<\/a><\/p>\n<\/div>\n

Penrith may have recorded 47.3C for at least one-second this week, but Windsor <\/a>is only 23 km north-east of Penrith, and on January 13th, 1939, it recorded 122F or 50.5C with an old fashioned liquid thermometer,\u00a0 not a modern noisy electronic one.<\/p>\n

Apparently, climate change makes our extreme heat less extreme.<\/p>\n

Furthermore, this was not measured on a beer crate in someones back-yard, but on the historic Windsor Observatory<\/a> which was built in 1863 by John Tebbutt<\/a> F.R.A.S who had discovered The 1861 comet, and published many scientific reports in Astronomical Journals. His meteorological observations are published at Harvard in 1899<\/a> (among others). Tebbutt died in 1916, so it\u2019s not clear what instrument the 122 F was recorded on in 1939, but a Stevenson Screen had been installed around 40 years earlier, and the measurement was made by Mr Keith Tebbutt, presumably his son.<\/a><\/p>\n

Tebbutt\u2019s portrait graced the back of our 100 dollar note from 1984 -1996.<\/a><\/p>\n

All part of Greater Metropolitan Sydney<\/h4>\n

In 1939, I doubt either town was considered part of Sydney. But now both are on the metro network.<\/a> Penrith is 54km from the CBD, Windsor, 56km. Notably, Windsor is a few train stops closer than Richmond<\/a>, which the BOM acknowledges recorded 47.8C in 1939 on January 14, three days after the high of 122F recorded at Windsor.<\/p>\n

Apparently Penrith that particular day, January 11th, was 110F, while Richmond was 115F or 46.1C. Neither Penrith nor Windsor appear to be recognised in BOM climate records.<\/p>\n

Extreme heat of long ago \u2014 48.2C (118F) at Windsor in 1896:<\/h4>\n
