November 2023 Weather at Durham – Very Stormy start

November 2023 overall saw about average temperatures. The first two weeks were mild and unsettled. It then became rather more settled; it was still mild in the south, but the final ten days were much colder as winds turned to the north, introducing Arctic air. The start of the month continued October’s wet and windy theme with Storm Ciaran bringing disruption on the 1st-2nd, with widespread damage and flooding, particularly in the south (and it was exceptionally severe in the Channel Islands and Northern France). A new record low atmospheric pressure for England and Wales was set in the storm, with 953.3 mbars in Plymouth and 958.5 mbars at St. Athan (South Glamorgan). At such a pressure the boiling point of water drops to 98.3C; there was some speculation about whether this fall affected the taste of tea. A particularly severe tornado hit Jersey during the storm overnight on the 1st-2nd, bringing large hailstones, rated as T6, across 8 km, the most severe tornado in the UK since 7 December 1954. Although the first half of the month was very wet, the dry second half meant that rainfall totals were about average, although they were still above average in the …

November 2022 Weather in Durham – Very mild and unsettled

November banner : fireworks

The Weather at Gilesgate, Durham November 2022 A very mild November at Durham, with the first half being especially so, but as usual in such a mild month it was also very wet. The peak of the month’s warmth was on 11th November, when 16.5 degC was reached. The night of 11th November was the warmest November night on record at Durham. The maximum actually reached 10 degC or more on 16 days in the month, which is quite respectable. There was only one air frost recorded (-0.3 on 29th). The outstanding event of the month was the extraordinary total of rain on 17th November. The total of 55.7mm was recorded during the passing of a depression and although the total was a mammoth one for Gilesgate, there is no special mention of it in Professor Tim Burt’s notes for Durham University, so it seems to be a hyper-local total. The total for 17th was 31.6mm there, so it may have been split over two rainfall reporting days. Note : The total for 16th-17th November 2022 at Durham University was 52.4mm. Their reporting retains the 0900-0900 throwback system, whereas at Gilesgate I report on a midnight-midnight system. The two totals …

November 2021. A very mild first three weeks, often settled and fine, but with a colder final week.

The lowest temperature of the month was -8.7 ºC at Shap (Cumbria) on the 29th. Storm Arwen brought notherly gales and disruption on the 26-27th, with many homes in the east of Scotland and northeast of England losing power, many for several days; the highest gust recorded was 98 mph at Brizlee Wood (Northumberland). There were 18 cm of snow at Middleton, Hillside (Derbyshire) on the 27th, and snow fell as far south as Bognor Regis (which is rare in November).  Overall the month was slightly warmer than average, with temperatures tending more above average the further north you went. It was generally a dry month, with 63% of average rainfall, and London and the South East only seeing 20%, the driest November since 1956, although it was wet in the far NW of Scotland. https://www.trevorharley.com/2021.html WEATHER WARNING !! We don’t need to do this often here, but the North East of England is …

November 2020 Weather in Durham – Mild and Dry

Forgive me for saying it, but I found the weather of November 2020 quite boring in Durham. There were no extremes of temperature, no extremely wet days and even the normally strong and boisterous autumn winds had little to say for themselves. The month began with low pressure in charge, dropping 10.1mm of rain in the first couple of days, but it was mild, and the mildness continued pretty much until the 18th. The actual maximum temperature occurred on the 5th of the month, when 16.7 degC was reached. The minimum came at the end, with the first air frost since Spring. Temps fell to -0.9 degC on the morning of 28th and suddenly things were a lot more seasonal. The mean temperature for November 2020 was 8.1 degC, which is well above average (6.1). It was 2.3 degrees warmer than November 2019 for example. The month had gotten itself into a bit of a rut in the first half however. Anticyclonic weather keeps the gales away at this time of year, but the payback is that the weather can often become cloudy and gloomy, and that is exactly what happened. Although the month was ‘damp’ as usual for November, …

November 2019 Weather in Durham – Wet, Dull and Pretty Dreadful

Cold, Wet and Cheerless Once again I have poor weather to report for this month in Durham. Particularly, high rainfall totals again and an incredible dullness that depressed. I know that November is sometimes a cheerless month, but this one has been really rubbish. The weather has also been cold, with depressed maxima by day, although not too cold at night until the last few days. I have had a bad cold for most of November and I blame it almost completely on the rank weather November has served up for us all. No sun – no moon! No morn – no noon – No dawn – no dusk – no proper time of day. No warmth, no cheerfulness, no healthful ease, No comfortable feel in any member – No shade, no shine, no butterflies, no bees, No fruits, no flowers, no leaves, no birds! – November! by Thomas Hood Rainfall The month was very wet. The total of 129.1mm was just behind the June total for wettest month of 2019. There were 26 days with rain and 6 days had more than 10mm. The rain put a big damper on the Durham Lumiére Festival with 5.6, 9.5, 13.7 and …

A Met Office Rainfall Graphic – Does it Help?

Here’s a graphic released by the Met Office, attempting to illustrate the wet weather we’ve had in the first half of November 2019. Now, the first half of November has been pretty wet. In fact 85mm of rain has fallen on Gilesgate since the start of November, continuing the soggy 6 months we’ve had. I looked at the map and was surprised to see that the Durham was in the white area. Usually this means ‘around average’ on Met Office maps. I checked the key and it says that white represents between 75 and 125% of average. Now this surprised me. The mean for November in Durham is 72mm. So, I would expect the average for the first 17 days to be calculated as (72 x 17)/30 = 41mm So, by my calculations we’ve had 85/41 times the expected rainfall for the first 17 days. That feels about right. More than 200% of normal. Yes, it’s been wet. Why is the graphic not showing the Durham area as Dark Blue on the map then? Well, i’ve been having the conversation with Liam Dutton, Jen Bartram and a few others on Twitter. The graphic is showing the first 17 days of …

November 2018 Weather in Durham – Typical November Weather

As is usual at this time of year, there is much speculation about the winter to come. After the brief episode of snow at the end of October 2018, the usual suspects were predicting a snowy November. As is nearly always the case, the snowy November didn’t happen. Temperatures were mild in the first half of the month, and stayed that way until the 18th, when an Easterly component was pulled in and colder, wetter weather ensued. Rainfall came in hefty showers blown in from the North Sea, peaking on 20th-22nd when over an inch fell. The thermometer stayed around the 5-6 degree mark during the day, but with the wind felt much colder. There was an air frost around midnight on 21st/22nd after skies cleared following the rain. Milder temperatures returned at the end of the month, but it became very windy as the Atlantic low pressure rolled in from the West, with more rain to finish. November is normally the wettest month of the year in Durham and November 2018 wasn’t far from the average overall. Latest November Posts

First really cold day of the season in Durham – Nov 21st 2018

Today was the first really seasonal day of the autumn. The wind was a cold north easter, with frequent blustery showers blowing in from the North Sea. Temperatures struggled to get to 7 degrees C on Tuesday 20th, then on Wed 21st we also had frequent hail showers. Precipitation totals were expected to reach nearly 25mm (1”) over the two days. Winds then fell light to allow the first Air Frost of the season as temperatures fell below zero around midnight. No widespread snow though, even though Madden and Co. had been predicting Snowmageddon in the popular press and will no doubt claim success. There has been some snow reported over the high ground of the Pennines, Scotland and Wales, with a few reports of snow (hail?) around the Brighton area. The average temperature for November is still well above the long term mean, and wind is likely to come from a more South Easterly point in the coming days. Latest November Posts

22nd November 2017 – Cloudburst and deluge in Durham

This was a very wet day, but most of the rainfall fell after 8pm on 22nd. We were travelling back home and had to pull the car over in Tudhoe as we couldn’t make out where the road was! Rainfall became absolutely torrential and 49.3mm was recorded in about 3 hours by the rain guage in Gilesgate. The Durham University met station recorded 39.2mm, which they say is the 50th wettest day ever recorded in Durham since 1850. From Tim Burt: November was warmer than average, but not exceptionally so. All three ‘mean’ measures were above average. Even so, the number of ground frosts (17) was also above average. It would have been a dry month too, except for the exceptional downpour on 22nd when a total of 38.2mm was recorded, the equal 58th wettest day on record at Durham since 1850. If we use the ‘meteorological day’ (starting 09:00), then the total was 39.2mm, equal to the total on 28th July 2013, the 50th equal wettest day on record and thereby the equal wettest day since 16th April 2005. There were some exceptional hourly intensities: 9.4mm in the hour ending 20:00 GMT; 9.2mm in the hour ending 22:00 GMT …
