Whale-watching tips

Time of day and weather have don't make a huge difference on a whale-watching trip. However, a tour can get canceled in case of a storm or really bad weather. Even when it's raining, whales come to the surface to breathe so it's possible;le to see them. However, foggy weather could make your excursion less pleasant. In the morning, the sea is calmer which generally gives a better chance to spot mammals. In the afternoon you can get better lighting for your photos, especially during the sunset. If you plan to use any internet-depending gadgets on your trip, keep in mind that the signal gets really weak off shore.

What to bring with you

Binoculars or a camera with a good zoom will definitely come in handy to help get a better whale-watching experience. Also, sunglasses, sunhat and sunscreen can be useful, especially if you travel around midday. You can pack some water and snacks, however, you can also buy food from a snack bar on the boat. You might want to bring cash for snacks, though, because credit card terminals depend on the internet, and if the signal is weak, the payment doesn't go through.

What to wear

It might be quite warm in Boston, but once you get 35 km (22 mi) off shore, it gets chilly and windy too. So it's advised to take a jacket or a warm sweater on your whale-watching trip. Shoes with rubber soles and closed toes is a must. Do not wear flip-flops. The boats are quite large and stable so they rarely provoke motion sickness. However, if you suffer from seasickness, make sure to bring some medicine just in case.
