Sunny Days? - Oh yes I think I can just about remember what they are like. I think we had one last May, didn't last though.
As far as spotting at EIDW, if you're fit an healthy it's possible to walk the boundary, about 6 miles I think. You will be able to log everything at the field from somewhere. The alternative is to take the airport bus to the long-term car parks at the back of the airport, that will shorten your walk somewhat.
There are many aviation sites that will give you more info on this topic.
