To compare this year with 1976 is really quite mendacious, as the latter was much, much drier. And as the BBC’s own chart shows, there have been eight other years since then with similar rainfall levels to this year. Indeed, in England, as opposed to England & Wales, both 1996 and 2010 had drier starts to the year).
In other words, this year is not an exceptional event, merely something you expect to see every few years or so.
And if you go back through the full Met Office record to 1836, we can see again that there is nothing at all unusual about this year.( Indeed, all of the really dry years occurred in 1976 and before:

Ross McKitrick and John Christy have published a new paper in the Journal of Hydrology.
Abstract : We estimate trends in US regional precipitation on multiple time spans and scales relevant to the detection of changes in climatic regimes. A large literature has shown that trend estimation in hydrological series may be affected by long-term persistence (LTP) and selection of sample length. We show that 2000-year proxy-based reconstructions of the Palmer Modified Drought Index for the US Southeast (SE) and Pacific Coast (PC) regions exhibit LTP and reveal post- 1900 changes to be within the range of longer-term natural fluctuations. We also use a new data base of daily precipitation records for 20 locations (10 PC and 10 SE) extending back in many cases to the 1870s. Over the 1901–2017 interval upward trends in some measures of average and extreme precipitation appear, but they are not consistently significant and in the full records back to 1872 they largely disappear. They also disappear or reverse in the post-1978 portion of the data set, which is inconsistent with them being responses to enhanced greenhouse gas forcing. We conclude that natural variability is likely the dominant driver of historical changes in precipitation and hence drought dynamics in the US SE and PC.

None of the US is currently experiencing severe drought. CO2 is at 410 ppm.

Compare with May 1934 – when half the US was experiencing severe or extreme drought. CO2 was 310 ppm.

Sensible drought-proofing policies for Australia are simple –
- Stop wasting water
- Build more dams, pipelines and pumps
- Build power stations capable of delivering cheap reliable electricity for pumping water and energising desalination plants.
