Ever wonder why Bangalore became India’s IT capital and not Delhi or Mumbai? The real reason is kind of hilarious: the weather. That’s it. Everything else stacked on top of that one fact.
Here’s the chain. Bangalore sits at about 3,000 feet — the highest big city in India. Sit that high up and you stay cool all year, no matter how much the rest of the country is melting. Then there’s the Palakkad Gap: a 30 km notch in the Western Ghats, and the reason Bangalore’s evenings stay wet even in summer, and the temperature stays cold even in summer. Hold that thought, because it keeps coming back.
Fast forward to the British. They beat Tipu Sultan in 1799, and their soldiers were stuck in a swampy spot nearby, dropping like flies from malaria. Bangalore was cool, dry, and healthy. Easy call. By 1809 they’d moved their whole army base there, and a city grew up around it.
British cantonment, 1809 — a health decision that built a city.
Once it was a proper city, the big names started rolling in, and each one dragged in the next. IISc in 1909 — Tata’s money, the Maharaja’s land, weather that could actually sustain research. HAL in 1940 — built inland so bombs couldn’t reach it in the war. Then DRDO, ISRO, and a pile of government electronics companies.
Every one of them cranked out engineers. Thousands of them. So without anyone really planning it, Bangalore ended up sitting on a mountain of technical talent.
Then the internet arrived. And here’s the fun part. Undersea cables can only come ashore where there’s a coast, so they hit three cities: Mumbai, Chennai, and Kochi. But the hub didn’t form at any of them. It formed in Bangalore, hundreds of kilometres inland. Why? Because that’s where all the engineers already were. Cables land on the coast, but the traffic goes wherever the brains are. And again, those servers needed AC to survive. They ran hot. Bangalore’s temperature did that job for free.
Narayana Murthy actually started Infosys in Pune, in 1981. Two years in, he moved it to Bangalore. Same reason: the machines ran hot, needed AC, and Bangalore’s weather did half the job for free. By the time he got there, everything else was already sitting in place too — the talent, the cheap costs, the cool air, the reputation. He didn’t build any of it. He just walked into an ecosystem that a hundred-plus years had quietly assembled.
One cool city. One advantage stacking on another for almost 200 years, plus a mountain gap 400 kilometres away doing quiet work every single evening. That’s how Bangalore became India’s Silicon Valley, and why it still doesn’t feel like summer even in April.
Hyderabad’s temperature is almost the same as Chennai’s now. But ever wondered how Chennai lost the race to Hyderabad and Bangalore?
