Best Time To Head To Mirissa

The ideal time to see whales is from November to December and from March to April. Anytime between November to April is good time to watch the whales. This is the peak season and the weather is pleasant too.

Sri Lanka experiences two monsoons and one must avoid travelling during this time.

1. The water is turbulent and choppy during monsoon season.

2. May to October is supposed to be off season. Whales are rarely spotted!

Hence, you should plan the tour from November to April. Start your day early in the morning and you will have a number of activities throughout. There is so much to do in Sri Lanka! You can also indulge in scuba diving or head to Kalpitiya for a dolphin spotting tour.

As for the whale spotting tour, sperm whales are most commonly spotted. The blue whale (the largest mammal in the world), the Minke whale (or Sharp-nosed whale), the melon-headed whale and the dwarf sperm whale are also visible.

If we talk about the best timing for whale watching, then you must start early in the morning. 6 AM to 7 AM is the best time to head out for a whale watching expedition. Afternoon is not the best time to explore Mirissa because the water gets rough and the heat may not be bearable for travellers.

Anything between 11:30 AM to 3:30 PM should be avoided as the water gets choppy and rough.

Wake up early in the morning, watch the sunrise, get closer to the whales, and enjoy a happy breakfast after the tour. Fill your tummy with some Hopper, Dahl, and delicious curries. Even South Indian breakfast is available in many restaurants!

Let’s cut to the chase and find out what type of whales you can find in Sri Lankan waters!

Whales In Mirissa

  • Blue Whale
    Watching a blue whale come out of the water is an incredible sight. The 150-ton whale, about 30 meters long, emerges its huge baleen and the upper part of its head, takes a great inspiration by projecting, through its vent, the water it has accumulated, before diving again and continuing its journey. Due to its status as the largest animal recorded today, the blue whale remains queen during these marine excursions.

    Please know a blue whale is quite gigantic! Line up a jeep and three buses and you get a blue whale. Did you know that a blue whale can eat 3500 kg(s) of krill a day? Since the body size is massive, the whale needs a lot more food. However, do not commit the mistake of feeding the whales. There is plenty of fish in the sea for them to feed on!

    Despite the large size, the Blue Whale can swim quite fast! In just one hour, they can travel up to 30 kilometers. A Blue Whale can live up to 90 years, and they swim in groups. Mostly, the fishes in the sea like to remain in their social group. Perhaps it is the best way to protect oneself, or they like being social.

    As per research, fishes swim together so that there is less friction and no extra energy is expended. When it is dinner time for fishes, it is easier to find food in a social group! Well, we just explained you how a fish socializes. It is interesting to know about the social behavior of aquatic creatures!

  • Minke whale
    It is the most common whale along the Sri Lankan coast, especially in summer. You will often have the chance to observe it during your safaris, because this Minke whale likes to follow the boats. It is the smallest representative of its species, with a height of 7 to 10 m and a weight of 8 to 10 ton. The Minke Whale has Baleen Plates and not teeth. If you see a comb, you would be able to make out what Minke Whale’s teeth looks like!

  • Melon-Headed Whale
    It is a rare type of whales worldwide. Its dorsal fin of the hybrid resembles that of a melon-headed whale. The upper half of her body is light grey, which makes her think closely. It is dark in color but not black, with a darker “saddle” well distinct below the dorsal, preceded by a dark “cape” on the top of the back.

  • Dwarf Sperm Whale
    Its rounded snout at the young age becomes square with age. A long white mark binds the eye to the pectoral making it like a «hearing» giving it a shark look. We note the presence of one or more furrows under the throat. Finally its vent as in the other sperm whales is located slightly on the left. It is about 2.20 m to 2.7 m long and weighs around 150-250 kg. Sperm whales eat octopus. Funny thing is that Blue Whales are larger in size, but they feast on smaller creatures like the Krill.

This whale is little active; we often see it on the surface, exposing out of the water the top of its body from the snout to the fin. Its body is then broken with a caudal sometimes up to the vertical. Under the impact of fear, it expels a brown-red cloud of feces (feces) stored in their voluminous rectal bulb.

Where Else Can You Spot Whales In Sri Lanka?

Apart from Mirissa, you can also head to Trincomalee for a whale spotting tour. Once again, November to April is the best time to head to Trincomalee. You can also visit Trincomalee from May to October. Since this is in the North-East part of Sri Lanka, it experiences a different monsoon season. It is easy to spot Blue Whale, Killer Whale, Sperm Whale, and Brydes Whale here.

Also, whales are getting extinct, it is advisable to take proper care and not scare away the whales. Ask the boat/cruise driver to NOT speed the boat/cruise. Speeding towards the aquatic creatures is not advisable.
  • When you spot whales, maintain silence and enjoy the beauty of the gigantic creature.  

Concluding Thoughts

Whale watching Mirissa is a must-do! However, there are certain behavioural patterns of tourists and cruise ships that are unacceptable. Considering the ocean belongs to the aquatic creatures, one must respect it. Before embarking on tourist ships, it is necessary to inform on the behaviour to adopt in front of the aquatic creatures such as cetaceans and blue whales in particular.

On 6 September 2012, the Sri Lankan government published a Charter (in English) outlining the rules to be followed in order not to disrupt the health and natural cycle of the animal. While the International Union for Conservation of Nature (IUCN) considers the conservation status of the Humpback Whale to be of minimal concern (lowest level), the Blue Whale is considered at risk of extinction.

The charter stipulates, for example, that vessels permitting the observation of cetaceans must have a licence issued by the Department of Wildlife Conservation, a public institution, and a registration number visible at 50 metres. These tourist boats can’t get within 100 metres of the whales to observe them, and are only allowed to sail between 5:30 am and 5:00 pm. They must not, in any case, disturb the trawlers set out for fishing at that time.

Some forty rules similar to these are enshrined in the charter. So, do not hesitate to seek advice from your agency regarding these excursion conditions!
In general, whether it’s on the South, East or West coast, you can observe marine mammals all year round in Sri Lanka! It is the ideal place to realize your dreams of children and to meet these marine mammals.
