It goes without saying that if you’re a fan of Rainy Season, you won’t find what you’re after unless you travel to the beauteous tropics. Rain is generated by nature there in huge amounts as a result of high warm/humid air levels in the so-called ITCZ. It means The Intertropical Convergence Zone. It moves from north to south, which leads to extremely wet/dry seasons (yes, we’re talking about a seasonal cycle here).
Now, if you’re serious about moving to a tropical country for the rainy season, make sure to grab your umbrella. Also, you will need your raincoat, but the light one. Unless you love to stand under the rain in t-short and enjoy a warm shower. That’s right – the rain is usually warm during a rainy season, so, keep that in mind. But in all fairness, monsoon weather is nothing to play with, and the noise can be very scary. It can wake you up in the middle of the night in cold sweat…
Find Shelter Before You’re Soaking Wet
We’re talking about an inch of rain/an hour, and don’t you dare to be stranded in the middle of nowhere when the rain hits, because the ice bucket challenge will feel like a piece of cake to you after this.
Besides, in the rain areas, your movement will be limited by the flowing water (ankle-deep, give or take) and poor visibility. So, again, make sure to find shelter before the cataclysmic event; otherwise, it might lead to unpleasant consequences.
Even if you survive the “awesome” wet season experience, you’ll have to dry all of your clothes after you strip down to your pants and save your dollar bills from the wallet. Your phone will probably be dead (unless it’s waterproof) and you’ll risk catching a cold.
True, the numerous travel guides don’t usually encourage tourists to visit a certain country during the hazardous rainy season months. Still, you can’t always plan everything perfectly, and a great new business deal will make you forget about everything and head into the storm especially if a big money is involved. Furthermore, even if you spent some time reading about rainy season, it may start a week earlier/later than it should.
The Science Behind Rainy Season
To keep it plain and simple: an epic seasonal monsoon is only possible when there’s a significant difference in temperature between the ocean and the land. Monsoons are generated when the position of the sun changes over time (in relation to the Earth’s equator – that’s pretty much it for our rainy weather description.
By the way, the word “monsoon” means wind, but these days we’re using it to describe the rain, the storm, and the wind. As for the magnitude of the monsoon, it’s safe to say that it has everything to do with a country’s proximity to the aforementioned equator and the ocean. Mountain chains also have a huge impact on it. Floods, scary lightning strikes, and typhoons are the most common features of the rain areas.
Different Regions, Different Rainy Season
It goes without saying that monsoons are not identical in the tropics, as the geolocation of the countries and their proximity to oceans have a huge influence on the patterns of rain and wind.
Usually, severe monsoons happen in the areas where the Indian and the Pacific oceans collide. Australia, South Asia, and India are among the monsoon-heavy regions.
So, when does rainy season start? It all depends on the patterns of the ITCZ’s movements: it “flows” across the equator and causes dry winters with wet summers. So, in that regard, the answer to your question – when is monsoon season in India – would, naturally, be summer.
Fact: the South Asian/Indian rains are probably the strongest as the huge rocky mountains in these regions prevent the dry air that comes from the other side from mixing with the humid atmosphere. The wet/dry region in Western Africa is yet another rainy area. Yes, monsoons happen in the American continent as well, but they’re quite weaker.
Asia, India, Australia In Wet Season
This region is famous for the mightiest rainy season on the planet, and it’s made up of the northern part of Australia and Asia, stretching from the vast SCS (South China Sea) all the way up to the gorgeous and impressive Indian Ocean. Generally, in Vietnam, India, and Thailand, monsoon rains start in June and end in September.
In winter (Dec-Feb), this region is consumed by the dry season, while the monsoons move further up – to Australia. And what about the East-Asian monsoon, you might ask, the one that “attacks” Japan and China? Well, it has a lot to do with a different wind pattern. Ok, so, which month has the most rain? Again, it’s a matter of where you’re currently living.
The Americas Monsoon
Depending on the season, the magnitude of rain is different in the North/Central/South American regions, and that’s also true for the areas where rainforests flourish. During summer (June-August), you’ll catch more rain north of the equator (that includes Panama and other countries).
During winter, however (Dec-Feb), the monsoon moves south, to Brazil. The potent NA monsoon brings humidity from the Pacific into the South-west of the United States, with more rain in Mexico, while, say, Arizona stays dry. At the same time, if humid monsoon winds happen to blow during this time of year, the rainfall will turn them into wet regions.
Africa In The Rain
Finally, let’s talk about Africa: there’s a vast area called SSA, and, during Northern Hemisphere summer, the Zone over this continent usually lies north of the equator. Generally, moist winds come from the Atlantic and turn into rain upon reaching West of the continent (Ghana and other countries).
As for the Southern Hemisphere summer, the Zone moves to the south (in relation to the equator), and countries like Uganda and Zimbabwe become rain-heavy. At the same time, SSA turns into a dry (and super hot) land during winter when the atmospheric air hits the ground. Alright, we hope that now you know what is the rainy season!
