There are many places where whales, dolphins, whale sharks, stingrays etc. can be seen by a guided boat tour, a snorkel trip or even from the costal line.
The best months to visit Hong Kong are October to April. The northern summer is the time of the monsoon. Keep in mind that HK is very busy during the Western and Chinese holiday periods and at weekends as well. The dolphin watching tours take part three times each week always on Wednesday, Friday, and Sunday. The trip has to be booked in advance.

The driest months are December to March. These are also the coldest months, therefore, more often sunny blue skies instead of clouds and high humidity. Avoid the summer months when you may experience downpours, and in September typhoons occur occasionally.
The dry season in the Yucatan runs from November until April. Since Sian Ka'an is only reachable by quite a rough road it is not advised to visit in the wet season, especially if you DIY.
The whales come to Tonga for two reasons; first for mating and second for giving birth eleven months later. A large population of humpback whales gathers around Vava'u Islands in Tonga between July and October. These months are the best time for whale watching as well as the unique opportunity to swim with a humpback mother and her calf.
Are Humpback Whale Sightings Guaranteed?
To be on the safe side book your visit between mid-July and end of September. The high number of whales in this area at this time means, there are plenty of opportunities to see them and swim with them. It's also the 'dry season' with less precipitation, less wind, and usually a calmer sea. If you decide to go in October: Whales are starting to leave late September, but especially mothers and their calves are still around in October which can lead to fascinating encounters.
How Long to Stay?
It's recommended to spent several days even better an entire week there, to maximize your chances of sightings and to swim with the whales. The whale watching tours take place in the open water. Sightings can't be guaranteed and the swell can be pretty high. Consider on Sundays none is working.
Where to Stay on Vava'u Islands?
There are not plenty of accommodations on Tonga; Vava'u Islands available. The most excellent hotel is the Mystic Sands Hotel with crystal clear water in front. You can get your pick up by boat for the whale watching trip from their jetty. Another option close by is the Tongan Beach Resort with a tasty restaurant.
The season starts middle of June until September. The highest chance for a sighting is also the peak season on the Hebrides in July and August. Anyway, no guarantee at all. I booked a four-day trip to increase the chance for snorkeling with one and I only saw a young one from the boat. One guy had booked a trip for the third time and our three meters tall shark was his first one. You need the right conditions and also a lot of luck!!
I'd recommend August now. This is also the month when the shark festival takes place at one weekend.
Migration of Humpback Whales from mid-December through mid-April. The peak time for this whales and most mating activity last from late December to January.
