What May feels like
The International Rose Test Garden usually hits its first big flush late in May, which is why the Rose Festival lands where it does. Showers still roll through, but they are the kind you sit out under an awning with a beer rather than go home for.
Rain arrives about 7 days of the month, so keep one flexible day in your plans.
