April and May
Spring
Schedule: NOAA says most Stellwagen operators begin in May, with some starting earlier; Dolphin Fleet says whales feed here from April. Confirm the first operating dates before locking in lodging or a ferry.
Comfort: Pack the warmest layers of the three seasons. Dolphin Fleet says the water can feel 10–15 degrees cooler than town.
Wildlife: Sightings vary widely. Choose spring for the quieter Cape, not for a promised species.
