To me, the chief sign of being in El Niño conditions is that weather forecasts tend to predict more rain than actually arrives - and for La Niña, the converse was true, the forecasts said "patter" and we got "splash!" and "splosh!" and "glubglubglub!".
And even though the Melbourne water storages are still slowly filling up, that's mainly due to the ground having being thoroughly saturated through summer and spring, rather than much winter rain being around. Not that I'm wishing for too much rain, but the storages have just limped back up over 60%, it would be a pity to return to the conditions where we lost 10-20% in a year.
I guess I'll just wait and see what Spring holds ... fingers crossed that it's a good one.
(... alternatively, maybe we spent A Little Too Long in Glasgow, if you know what I mean)
Edit: We have a steel roof. The pattering noise I can now hear on the roof is ... irony.
