Darwin Airport ( 1941-2021 ) 12.4239°S 130.8925°E 30m AMSL. The warming trend continues......September was another well above average month for both max and min temps. In fact the mean max of 34.1c was the highest since records began in 1941. The previous record of 34.0c was set in 2017. There was also a new record max of 38.0c, exceeding the previous record of 37.7c in 1983. Min temps were 1.0c above average at 24.0c. Rainfall at the Airport came in at 26.2mm falling on 3 days, exceeding the average of 16.5mm. September is still a dry season month, the median ( ie what one can expect ) is only 6.4mm. Suburbs closer to the City did much better, with a guage at the Botanical Gardens recording 38.1mm. Meanwhile my home PWS only recorded 7.8mm for the month, pretty well what we expect in the Desierto de Leanyer in the early 'build up' months. Inland regions of Darwin generally do a bit better with the early storms.   |

Sheffield September Summary 2021 September was a better month than the awful August with a higher average maximum temperature, much higher maximum temperature and probably a lot more sun. A decent month.

This September has been warm, dry, and very stable temp-wise—but without any real heat waves with high pressure aloft remaining in control more than usual for September, with the only substantial (which was sluggish) cold front bringing some rainfall in the morning of September 17th. In addition, this September has been the second warmest on record for Ciampino AP going by means—only behind 1987 as well as being the single driest JAS timeframe on record since 1951.   Average dew point (true average): 15.7°C (60.2°F) Average dew point (min. dew point + difference between max/min DP / 2): 15.7°C (60.3°F) Average 9 AM dew point: 16.4°C (61.5°F) Average 3 PM dew point: 16.9°C (62.5°F) Max. dew point: 22°C (71°F) on September 26th and 27th, 2:50–4:20 PM and 1:45-4:35 PM respectively w. fluctuations Min. dew point: 8°C (47°F) on September 14th, 11:40 PM Max. rainfall rate (instantaneous): 4.47"/hr (113.5 mm/hr) on September 8th, 3:10 PM Max. rainfall rate (15-min. average): 1.24"/hr (31.5 mm/hr) for September 8th, 3:05-3:20 PM Daily, hourly and 5-minute charts:  Weather boxes for the two main airports of Rome area:   Anomalies [for Ciampino AP; relative to 1991-2020 raw normals]: Average high: +2.8°C (+5.1°F) Mean: +2.4°C (+4.3°F) Average low: +1.9°C (+3.5°F) Precipitation: –61.7 mm (–2.43"; 13% of normal) |

September has been colder and wetter than normal, fortunately has not become the coldest in this century, at least in Riga.
Mean: 12.1C
Lowest: 4.0C on 19 September
Highest: 24.0C on 10 September
Precipitation: 81mm ( normal would be 66mm)

Average September conditions
Mean maximum: 25.3°C | Average high: 17.7°C | Daily mean: 12.8°C | Average low: 7.8°C | Mean minimum: 1.9°C
Average precipitation: 42.9mm | Average precipitation days (>0.2mm): 13.8 | Average relative humidity: 69% | Mean monthly sunshine hours: 186.0
Quite a decent September by Melbourne standards, with relatively high rainfall totals and some variability. Temperatures were near average, but both rainfall and sunshine hours were significantly above average. A large portion of this month's rain came from a single event on the 4th-5th. Oddly, the highest temperature was recorded early in the month, on the 2nd, while the lowest occurred on the morning of the 27th.

Pretty much what I expected for Cranbrook after last August. Slightly above normal temps, slightly below normal precip. Had two good thunderstorms, otherwise it was pretty pleasant/boring. West Vancouver had a shitton of rain and even a few thunderstorms as well.  |
