Yn ddiweddar, mae Llywodraeth Cymru wedi cynnig cyllid ar gyfer datblygu ymhellach Wythnos Bysgod Sir Benfro. Ar ôl cychwyn yn 1999 fel digwyddiad bach yn canolbwyntio ar gystadleuaeth sewin genedlaethol, cynhelir yr ŵyl bellach dros wythnos ac mae’n cynnwys dros 250 o sefydliadau a busnesau mewn dros 500 o ddigwyddiadau cyhoeddus a gweithgareddau ledled y sir. Dechreuodd Gŵyl Steelhouse ar Fferm Hafod-y-Dafal ar ymyl ddeheuol Bannau Brycheiniog gydag ychydig yn llai na 1,000 o ymwelwyr yn ystod penwythnos yn 2011. Mae wedi tyfu bob blwyddyn ers hynny ac roedd cynulleidfa o dros 10,000 yn 2016. Cynhelir pedwaredd ŵyl “The Good Life Experience” gan Cerys Matthews ar Ystad Penarlâg ym mis Medi.  Mae Llywodraeth Cymru wedi cytuno i ariannu’r gwaith o ddatblygu’r ŵyl yn ystod y ddwy flynedd nesaf.  Cynhelir Diffusion, gŵyl ryngwladol ffotograffiaeth Caerdydd, hefyd ar ddiwedd y mis.
The Welsh Government has also recently offered funding for further development to the Pembrokeshire Fish Week – having started in 1999 as a small event focussed around a national Sewin competition, the festival now takes place over a week and incorporates over 250 organisations and businesses in over 500 different public events and activities across the breadth of the county; the Steelhouse Festival  in Hafod-y-Dafal Farm situated on the southern edge of the Brecon Beacons  started out with just under 1,000 visitors over the weekend in 2011 has now grown year on year to a total audience of over 10,000 in 2016. The 4th edition of Cerys Matthews’ Good Life Festival will take place at the Hawarden Estate during September and the Welsh Government have agreed to fund the future development of the festival for the next two years.  The Diffusion Festival - Cardiff’s International Festival of Photography also takes place until the end of the month.
