I'm thinking about signing up for IM Maryland.. Reading about prior race reports, was last year an anomaly? I don't want to race in 40'F weather lol.
What are typically weather like there in October? Website says water is high 70s?
Also read that there are jellyfish?
It is usually really nice that time of year. 60's temp but it can get windy.
We bay locals call those jellyfish sea nettles. Some years they don't make an appearance and others are bad. The last year of the Chesapeake Man (2013?) race they were bad. Late summer was mild. You just have to wait and see.
