Just 2.8mm in the first 22 days but a horror spell of 9 consecutive rain days (which has only happened once before in May in the last 20 years) has taken the total to 41mm so barely below average.

Same thing happened in June 2023, September 2023, July 2018, July 2013. Just can't get the same sustained dry periods as in the past. May 1859 had only 5mm and is the driest May on record. Can't see anything like that occurring again in this dire day and age.

I can't adequately express the contempt I have regarding the nonsense being spouted about water scarcity given how horrifically wet the past few years have been. Why these parasites aren't being challenged by the media I don't know. My garden was like a sopping sponge last weekend after the torrential downpours showing just how saturated things remain. Even if there was no rain until September the three year rolling total would remain well above average.

Whenever I produce my weekly water scarcity reports on here, the viewpoints which I give are usually always those expressed by SEPA (who provide the information for these reports), and not actually my own viewpoints as I always try not to get too involved in that particular argument myself if I can possibly help it (although it does have to be said that if rivers are drying up because of a lack of rainfall, that is a very serious matter which we all have the right to report on here). My aim here is therefore to quote what those weekly reports from SEPA are saying and then allow others on here to make up their own mind about that should they wish to do so.

SEPA are really just a Government Quango though under the auspices of this Scottish Government but if you have any issues with that or of their weekly reports, it might be worthwhile bringing that up in either a new or existing other thread in the UIA Forum, particularly if there are any views of a political nature which are being expressed as part of that. That way, this thread can then be used to either report rainfall totals for any given location, or other data relating to that such as groundwater and river levels from a more technical aspect.

Reservoir levels in East Sussex (West Sussex doesn't have any major ones) - Ardingly 89% full, Arlington 87% full. In general (from an AI scraped report) reservoirs in the south are mainly in the 80s%, but these figures drop off further north e.g. Vyrnwy (N Wales, serves Liverpool) 72%, Haweswater and Thirlmere (serve Manchester) 47%.  The southern reservoir levels are typical for this time of year but the northern ones are much down; Vyrnwy would be 92% and the Lake District 80% at this time.

I suspect - can anyone confirm? - that southern reservoirs are filled by pumping, and there was plenty of water to be pumped in the south last Autumn (remember those floods?) but the north was drier and relies on run-off.

Data For Recent Days

24 hour total up to 10 am BST (09:00 UTC) this morning: 3.6 mm

Monthly Data

Final total for May 2025: 37.6 mm (74.9% of 1991-2020 May average)

Number of rain days during May 2025: 8 (74.3% of 1991-2020 May average)

Number of dry days during May 2025: 22

May 2025 was yet another drier than average month both in terms of the actual rainfall amounts and in terms of the number of official rain days. In fact, not even a single drop of rain was recorded until the very last week of the month and yet a much wetter end to the month was enough to make May 2025 our wettest month of the spring.

Seasonal Data

Final total for the spring of 2025: 88.4 mm (59.5% of 1991-2020 spring average)

Number of rain days during the spring of 2025: 17 (56.2% of 1991-2020 spring average)

Number of dry days during the spring of 2025: 61

The spring of 2025 was substantially drier than average overall both in terms of the actual rainfall amounts and in terms of the number of official rain days with all three months being drier than average.

Annual Data

Total for this year so far: 187.2 mm (23.9% of 1991-2020 annual average)

Number of rain days during this year: 35 (25.5% of 1991-2020 annual average)

Number of dry days during this year: 91

52.5mm for Spring, 13 rain days, max 21mm on April 15th.

In terms of Spring 2025, my total comes to 50.5mm, making it the 3rd driest Spring I've recorded, behind 2020 (34mm) and 1990 (35mm).
