The wettest was 258.3 mm in 1918 which is also the wettest of any month in Bristol. The 187.7 mm in 2024 is 295.1% of the 30 year average (1991-2020).

Winds were light and mainly from a north easterly direction. The lowest pressure for the month of 983.6 mb on the 26th was the 2nd lowest for a September since 2005 when the data started.
The highest maximum daily temperature of 23.2°C on 1st of September was the lowest since 2017 when 21.3°C was recorded. The lowest daily mean of
10.7°C recorded on the 13th was the lowest since 9.7°C in 2012.

With an average temperature of 17.4°C it was 0.3°C below the 30 year average (1991-2020) of 17.7°C. The average maximum temperature of the summer of 21.4°C was 0.5°C below the 30 year average. The average minimum temperature of 13.7°C was 0.1°C above the average temperature.
The summer rainfall was below average with 139.5 mm for the 3 month total. It was the 24th driest in 143 years of data. The 30 year average summer rainfall is 212.7 mm so 2024 was 66% of the average.

The Meteorological site is situated in an urban housing area approximately one mile to the south of the Centre of Bristol. This area is in a district called Totterdown.

Statistical correlations with the Bristol Meteorological Office site, that was less than two miles to the North and was situated on top of a City Centre office block, were generally good with rainfall and barometric data particularly close.

The site of the station is approximately 34 metres above sea level with the manual instruments mounted in a Stevenson screen. The screen is sited centrally in a small concreted garden area. A Snowdon rain gauge is mounted correctly in the ground but does not have the full open space required around it. A  Davis Vantage Pro2 Plus automatic weather station (AWS) was added in May 2005 and this is mounted 4 feet above a concrete shelter. The wind data is gathered automatically from a Davis Vantage Pro2 Plus anemometer which is sited 3.3 metres (10 feet) above the house top.

Manual observations are still taken at approximately 09:00 hours GMT every day for rainfall and cloud cover. Rainfall manually recorded in the Snowdon rain gauge is entered for the previous day. The wind data is constantly logged and automatically reset at 24:00 hours GMT every day (in the summer BST -1 hour. The Davis rainfall tipping bucket was recalibrated in November 2005 and is now consistently under 3% under recording (an improvement from installation in May 2005 when 10% was more typically the norm).

Since the arrival of the Davis Vantage Pro2 Plus equipment in May 2005 temperatures, humidity and barometric pressure are recorded from the new equipment. These figures will be more accurate and will be taken at exactly 09:00 GMT (in the summer BST -1 hour) as the data is now logged to a computer.

By default the Davis equipment records every parameter for the 24 hour period 00:00 to 23:59 BST or GMT. Data analysis will enable manual data extraction of temperatures and rainfall to 09:00 GMT (adjusted in the summer). Due to the 0.2 mm (tipping bucket) measurements of precipitation recorded by the Davis equipment the Snowdon rain gauge will still be used due to its greater accuracy (see above).
