Tuesday, July 12, 2016, 3:35 PM - Southern Ontario is at the start of yet another stretch of uncomfortably hot temperatures.

Daytime highs are expected to reach or exceed the 30oC mark in many cities, feeling even hotter with the humidity. Toronto is set to cross that mark on Wednesday, feeling like 37 with the humidity.

Anyone who lives in southern Ontario knows it can get that hot and humid occasionally, but it's always a little jarring when you look at your thermometer in Canada and find that it's about as hot as places considerably famous for being tropical.

Here are a handful of famously sweltering cities that Toronto will be rivalling on Wednesday.

Bangkok, Thailand

Thailand's capital is a thriving metropolis and tourist Mecca that also famous for being super hot.

The city's forecast Wednesday high of 31oC, feeling like 37, is not far off from Toronto's forecast -- or from the city's year-round average temperature, which is consistently above 30oC with little monthly variation.

Jakarta, Indonesia

A good ways to the south, Indonesia' capital of Jakarta has some 30 million people in its metropolitan area. The island on which it is located, Java, is the world's most populous, at more than 140 million inhabitants, more than half of Indonesia's entire population.

It's also close enough to the equator for the seasons to have little meaning as far as temperatures go. Its Wednesday high of 30oC, feeling like 36, is about average for the summer months.

Kolkata, India

Once known as Calcutta, Kolkata was an important centre during British rule in India and a centre for the country's independence movement. Now the city, located on the Bay of Bengal, is the beating heart of India's third largest metropolitan area, and a major commercial and financial centre.

Kolkata will feel like Toronto on Wednesday morning, but the afternoon brings even hotter temperatures, with a daytime high of 34oC and a humidex reaching 40 ... which sounds hard to take, but is not all that much worse than what Toronto will be experiencing.

Shanghai, China

Now HERE is a city famous for being an economic powerhouse.

Shanghai is the largest city in China, with around 24 million people in the city itself, not counting the metro (by some measures, it's also the most populous city-proper in the world).

At 32oC, it's set to be a couple degrees hotter than Toronto on Wednesday, but with higher humidity, that'll feel like a dangerously uncomfortable 42.

Kinshasa, Democratic Republic of Congo

Kinshasa, on the Congo River, is set to hit 34oC on Wednesday, but the humidity will be such that, at 34, it will "feel" slightly less hot than Toronto.

As the capital of the Democratic Republic of Congo, it shares many of the struggles and instability faced by the country as a whole. However, it is a major cultural centre and, with French as an official language, it is the largest Francophone city in the world outside of Paris itself.

Alexandria, Egypt

Famously founded by the Macedonian Alexander the Great as a side-stop on his attempt at world conquest, the Nile Delta city is more than 2,300 years old.

Its Wednesday forecast high of 30oC matches Toronto, though people in the city have it easier than the capital Cairo, downstream along the Nile. Alexandria's climate is moderated somewhat by its location on the Mediterranean, whereas Cairo's average daytime highs are usually in the mid-30s at this time of year.

Kingston, Jamaica

Jamaica's capital and most famous city is looking about as hot as Toronto for Wednesday, with a high of 31oC and feeling like 37. Canada's most populous metropolis is as hot as the Caribbean, where winter has a very different meaning than it does up here.

Incidentally, that's only slightly hotter than Kingston, Ontario is expected to get, feeling about the same with the humidity. Jamaica's Kingston became the most important city on the island after an earthquake caused the city of Port Royal to topple into the sea in the 1600s. Ontario's Kingston served briefly as the capital of the united Colony of Canada, and was the home of John A. MacDonald, the first prime minister of the Dominion of Canada.

Manaus, Brazil

Toronto will be about as hot and humid as Manaus, which should give you an idea of how extreme a heat event this is: Manaus is literally in the middle of the Amazon jungle, and so close to the equator that the seasons are meaningless.

But if you're picturing a collection of grass huts, nothing would be further from the truth. Like many Brazilian cities in the Amazon, Manaus is a large and developed community, with some 2 million people and major manufacturing and tourism industries.

Rio de Janeiro, Brazil

Toronto's Wednesday temperature will be about what Rio de Janeiro's daytime high of Tuesday, in the low 30s, was expected to reach. Wednesday itself will see a high of a mere 26oC, so Toronto will, in fact, be hotter than Brazil's most famous metropolis.

This is cheating a bit, as it's actually the middle of winter for Rio (ponder that for a moment), and the city's legendary warmth will likely persist through the Summer Olympic Games, which are set to open on August 5.

Death Valley, California

And you know, while we're here, let's check in on Death Valley, California, famously the site of the world's hottest-ever recorded temperature.

That was 56.7oC, a terrifyingly hot record set back in 1913 (hey, at least it was a dry heat). Wednesday is not looking remotely that hot, though the site's 45oC daytime high is a fair bit lower than Toronto's.
