@freddie, very informative, thank you.

My barometer has hit 956.3 so far today 2nd Nov 2023, lowest Ive had (so far) since 2005!

Thank you for the useful info. My minimum pressure was 955.2 at 5:45 this morning and I live very close to Bournemouth. We were very lucky being so close to the centre I think as the wind wasn’t anything like as bad as I’d feared, max gust only 30mph.

My barometer has just started to creep up now (957.4hpa).

Yes, the actual track of the low was about 20 miles further south than the model forecasts suggested.

953.9 is my new record.

I'm not too far from Wareham and 953.9 is also my new record - about 40 minutes after yours.

The highest annual rainfall of 40.26” in 2012 was broken here this evening with another 45 days of 2023 remaining.

Mine was broken some time ago and I am now 25% higher than my previous record, but my Burnham-on-Sea records only go back 4 years.

This has a lot to do with it !!

Interesting all those British records, yes. So what is it in the Netherlands? In terms of rain it is pretty bad: the West and North West is almost inundated with saturated soils and pumping stations on continuous duty. If they were not there or would be deprived of energy we would have been flooded from the inside (i.s.o. what everybody is expecting: from the outside). And that is without the rivers (Rhine and Meuse) on the rise. The line north of SW to NE is approaching 200 mm having already had some 200 mm in October where some 70-80 mm would be normal. My own station recorded the longest wet period so far of 33 days (the 34th day is today) and so far no stop is in sight. OK, I only have a series of 4 years

But that is not the only story about this year. From 17 May - 19 June I recorded the longest dry period of 34 days. Dryness is dangerous as well because the waterlevels drop and that causes the bogs to shrink (the peat settles or the peat compacts). One way or another the weather changes cause havoc everywhere.

A recent study has been made on how to deal with sea level rise of 3 meters. It causes a serious problem in the Low Lands by the Sea (of which the UK also has areas). The study focussed on the impact of reconstructing the dykes. But - although not yet outspoken - I already read elsewhere that evacuation of the Low Lands are already seriously discussed privately (inside chambers).

Rain is a symptom and long rain periods have been seen before but it is the context of multiple extremes which cause concern.
Weather is the thermometer of the climate change.

Strange isn't it, I'm thinking is my rain gauge faulty? This year so far hasn't even appeared in my top 10 at 748.5 mm. In tenth place at the moment is 2020 with 807 mm.

Same here Mark, it has been quite localised. My yearly total is sat at 652 mm. The average annual total is 795 mm, so still quite a way to go and I will be surprised if it is exceeded. Drier than average months have been the thing here this year (6 out of 11 months below normal), with February having only 12% of expected. There have been wet months - March, July, September and October - but the dry month deficits are higher than the wet month surpluses. Like Hans, if it rains today this will be the 34th consecutive day with rain recorded. Also like Hans I had a 29 day dry spell in May and June.

Hi Mark, I often compare our readings and do feel your station is under-recording. I know you've stopped uploading to WU but it is a useful way of comparing readings from nearby stations. Given our stations are only 4 miles apart I'm surprised at the significant difference. I suppose mine could be over recording but it's only 2 years old so you would hope it's accurate.

There's a station in Handforth using Davis kit and his readings are close to mine. IWILMS14

Well from sunny Jersey the rain has not really stopped for the past 21 days, some sunshine in the month but not a lot.

The total rain so far this month is 206.6mm out of an annual rainfall to date of 806.6mm and that is after February and June being unusually dry months. the normal average rain for the year to the end of November is 740mm. Needless to say every where is very soggy and the reservoirs are filling nicely. That said we have had a couple of dry years recently and prior to that we regularly had above average annual rainfall.

I suppose the other indicator of a changing climate is the temperature and we are consistently about 2.3C above the 10 year norm for each month this year. I cannot remember when we last had a frost and snow is something that only happens every 15 years or so.

This page is useful for an areal assessment of where has been wet or dry. Select the anomaly chart from the drop-down, select the rainfall parameter and step through the months for this year. You can see how dry February, May, June and August have been over large areas, with the months of January, April and September being close to average. Which only leaves March, July and October which were wet. This lines up with what I've seen from my station. I don't know how this month will pan out - I've had 56 mm so far (average around 80) which is about 70% of normal. The forecast isn't suggesting anything spectacular so I guess it will end up drier than average. December is going to have to be something special for it to end up a wet year here.
