Our own jellyfish (the stinging Sea Nettle) is absent from our waters this year. The usual "arrival" date is considered to be July 4. I've heard they have put in an appearance in the nearby Patuxent River.
They are not missed.
I would note, that despite higher than average salinity this year in the mid Bay, Sea Nettle populations are much lower than normal. Curiously, the NOAA Sea Nettle prediction center is not currently working. Even though the data for the two simple parameters used to predict them (temperature and salinity) are measured at many sites. Hmm, maybe it's not as easy as they thought.
