Despite the fact that it seemed like the worst May on record, it was by no means the wettest or the coldest here. It was a little milder and wetter than average, but I think last year's beautiful May spoiled us, and this year was in fact, very similar to May 2009.
What seems record-breaking (in my subjective opinion Posted Image), is:
26 days with precipitation, 23.5 days with fog (not necessarily the same days), and only 4 dry days (no RDF) for the month ! Only ONE (1) "mostly" sunny day, yesterday, May 31st.
