Boston Whale Watching: Morning or Afternoon?

Morning, in most cases, and the reason is the sea rather than the whales.

Why morning usually wins

Wind over Massachusetts Bay tends to build through the day. A morning departure more often crosses flat water; an afternoon one more often does not. Over four hours that difference is the whole experience, particularly if anyone in your party is prone to seasickness.

Flat water also makes spotting easier. A distant blow stands out on glass and disappears in a chop, so calm conditions raise your effective sighting rate even when the same animals are present.

Why the whales are indifferent

Humpbacks on the bank feed when the food is there, which is throughout the day. There is no reliable morning-or-afternoon pattern in their behaviour, so anyone telling you the whales are “more active” at a particular hour is guessing.

When afternoon is the better call

If the forecast is genuinely calm, an afternoon trip gives lower sun and better light for photographs. It also fits better around a morning in the city.

The seasickness rule

Take something before boarding, not when you start feeling it — by then it is too late. Stay on deck in the air rather than below, and look at the horizon. Most people who have a bad time on this trip had a preventable one.
