I came across this in the Daily telegraph when looking for records of actual rainfall (rather than forecast): April-could-break-rainfall-records-but-wont-end-the-drought.html


If anyone does find a site routinely recording UK rainfall measurements please do post the URL.


[Ed: the best I've found so far are the weekly and monthly water situation reports at http://www.environment-agency.gov.uk/homeandleisure/drought/31749.aspx.]

I reckon that in the time since you posted this, it should now have risen to about normal.

I am afraid that it is now too warm for any rain to make any real difference to the drought.


Basically, from April on the plants are all growing (ie using water in transpiration/breathing, transferring it to the atmosphere from the soil) plus the (relative!) warmth of the temperatures mean that evaporation and transpiration removes most of the water form the soil, so none can seep down into the aquifers in the rock, or even flow into the rivers (apart from a few flood events in the latter case).


Essentially, we need rain in the period from late Oct to end March in order to end this drought.

Well it's not the fault of Thames Water - yes I know they made an operating profit of ?600million last year and I know they've just put prices up 6.75% and I know they are losing 673million litres a day in leaks and have just imposed a hosepipe ban punishable with ?1000 fines but it isn't their fault and it would be typical of you leftie liberal cardigan-wearing bath-taking garden-watering car-washing veggie fascists to suggest that it was. You lot just hate a successful business don't you?*

I don't need to water anything at the minute wee quinnie. Nature is doing it for me.


I just thought the irony of hose pipe ban followed by wettest April on record was amsuing and worth discussing.


If I need to water, my solution will be, children, pocket money, get those watering cans..

Well - perhaps all of you experts were slightly off the mark about winter rain etc. The hose pipe ban has been lifted. I cut the grass and ran out to buy a new garden sprinkler, just before it started raining again.

Mick Mac,


To be fair, no one could have predicted the massive rainfall we have had through April, most of May and pretty well all of June so far. Also, the temperatures have been lower than usual for most of this period (because it has been raining!) - meaning less evapo-transpiration, and so we have the very unusual situation of groundwater levels eventually beginning to rise in June. Pretty much unprecedented.

Show nature can always kick accepted science in the teeth if she wishes!
