A spokesman for the Met Office says it has been the wettest winter on record across England and Wales - where the precipitation records date back to 1766.
Some 435mm (17.1 inches) of rain fell from December 1 to February 24, beating the previous highest total of 423mm (16.6 inches) set in 1915.
Provisional rainfall figures show that the UK as a whole has had its wettest winter since records began in 1910.
Some 517.6mm (20.3 inches) of rain fell this winter, the previous highest total was 485.1mm (19.1 inches), set in 1995.
England and Wales endured the wettest winter in almost 250 years, according to new analysis from the Met Office.
Denbighshire Council has called for the Welsh Government to provide grants to houses damaged by recent flooding.
"The time is now for the Welsh Government to provide direct financial assistance to households affected by the winter flooding, in the same way that UK Government is providing £5,000 per household in England" said Councillor David Smith.
Cllr Smith said the repair cost for coastal defences in Denbighshire is approximately £1.8m.
"The Welsh Government has already pledged around £4.6M for those repairs - but nothing yet directly for households affected".
The Prime Minister has visited a flood-hit part of Wales, but refused to say whether homes and businesses here will be exempt from council tax, as he plans in England.
The Westminster Government has set aside £4m to finance the support in England, but insists that flood support here is devolved to the Welsh Government.
The Welsh Government seem to have been disappointed in their hope for extra flood repair money from the UK Government. Even though David Cameron told me Pembrokeshire that there would be nothing extra, others, notably the Welsh Government saw in his very visit a hint there would be some new cash.
Its expectation increased after David Cameron announced money for councils to give council tax rebates to flood-hit households without specifying if that meant English councils. The Welsh Government's now got clarity and it isn't happy.
Natural Resources Minister Alun Davies said:
David Cameron’s visit to Wales has caused serious confusion and upset. Whilst in Wales he announced on social media that ‘we will fund councils that give council tax rebates to people whose homes have been flooded.’ There was no ambiguity to that statement.
Communities he was visiting today would obviously expect the support announced today, in Wales, to be available to them. We now understand that Number 10 has clarified his remarks and there will be no extra support for Welsh councils and businesses. That’s a real disappointment to those people in Wales he’s been visiting today. I have to ask what the purpose of today’s visit was, beyond an attempt to get a few local headlines.
The Welsh Government says it is "absolutely committed to supporting and funding tree planting" in Wales.
We are absolutely committed to supporting and funding tree planting in Wales and we are confident that uptake of the woodland creation element in our Glastir Woodlands Scheme will continue to increase in the next Rural Development Programme period.
We are currently consulting on the future of our agri-environment schemes and on the final proposal for the Wales Rural Development Programme.
We worked closely with the Woodland Trust in drafting proposals for this consultation to ensure that their views were reflected and are very grateful for their contribution.
Could nature provide the solution to the devastating problem of flooding? One charity says simply planting trees could protect thousands of homes.
Coed Cadw - the Woodland Trust - is calling for the Welsh Government to plant 10 million trees over the next five years.
Political Editor Adrian Masters asked the Prime Minister about the public split within the Welsh Conservatives and if he backs Andrew RT Davies following the reshuffle in which he sacked four Shadow Cabinet members.
Welsh Labour has seized on the absence of Andrew RT Davies at the Prime Minister's side during his visit to flood-hit Pembrokeshire as proof of a 'snub' by David Cameron to the Welsh Conservative leader.
Labour party sources are linking it to the public split between Mr Davies, some of his Assembly Members and the Welsh Secretary which led to the sacking of four Shadow Cabinet members. A spokesman said:
The growing divide within the Tories has taken a serious turn for the worse today. That David Cameron has snubbed the Welsh Tory leader Andrew RT Davies - especially given flood defences are devolved - is both hugely embarrassing and telling of the way the supposed leader if the Welsh Tories is viewed by his colleagues in Westminster. RT can take some comfort in the fact that the situation could be worse. He could have found out he'd been snubbed by the Prime Minister on twitter."
