June 2026, Thane. Outside, the heat is sitting at 42 degrees. The fan is doing nothing useful. The sky has that white, washed-out look it gets just before the monsoon decides to show up... or not.

This morning, news broke of a 7.8 magnitude earthquake off Mindanao in the southern Philippines. At least sixteen people confirmed dead, buildings reduced to rubble in General Santos City, a one-metre tsunami washing into coastal villages. By evening the death toll was still climbing. A tragedy, clearly. The kind of event you read about, feel the weight of for a moment, then scroll past.

But here is the thing about being curious. You do not scroll past. You sit with it. You look at it from another angle, and then another, until something unexpected opens up.

The question that nagged at me this morning was a strange one: could this earthquake, happening thousands of kilometres away in the Pacific, somehow touch the monsoon that most of urban India is anxiously waiting for?

The short answer is no. Not directly. Not in any measurable way.

But chasing that wrong question led somewhere far more interesting.

The Wind Map and What It Shows

Open any wind visualisation tool, Windy or earth.nullschool.net, and pull up the Southern Ocean view. Look at it on June 8, 2026, and then compare it to the same date last year. The difference is noticeable even to an untrained eye. Last year, the Southern Ocean was churning with well-defined cyclonic systems, large spiralling masses of green and white spinning energetically around Antarctica. This year, the picture is quieter. Fewer distinct systems. The swirls that do exist seem tighter to the continent, clinging to the polar edge rather than reaching northward into mid-latitudes.

This is not a dramatic visual. But experienced pattern-recognition, the kind you develop by looking at the same maps week after week across seasons, tells you something is different.

It turns out, the data agrees.

The 2025-26 South Pacific cyclone season was the least active on record, tied only with the 1990-91 season. Just two named tropical cyclones for the entire season. The year before was not much better. Two consecutive historically quiet seasons in the South Pacific sector. That is not noise. That is a signal worth investigating.

The Churning That Was Not There

Here is something most people do not know about the Southern Ocean. The extratropical cyclones that spin around Antarctica are not just storms. They are the mechanism. They are the engine that maintains what scientists call the Southern Annular Mode, or SAM, the dominant pattern of atmospheric variability in the entire Southern Hemisphere.

These travelling cyclones carry momentum poleward and equatorward. They churn the atmosphere the way a spoon churns tea. When they are active and numerous, the belt of westerly winds around Antarctica stays robust and well-positioned. When they weaken or push too far south, that entire belt shifts, the jet stream repositions, and the effects cascade northward in ways that take weeks or months to fully appear.

The SAM right now is at its most positive state in over a thousand years. A thousand years. This is not a seasonal fluctuation. This is a structural shift driven by decades of greenhouse gas accumulation and stratospheric ozone depletion. A strongly positive SAM means cyclone tracks are pushed poleward, hugging Antarctica rather than reaching into mid-latitudes. Less churning where it matters for the tropics.

The Southern Ocean is still spinning. But the energy is in the wrong place.

Meanwhile, in the Pacific

A separate story, happening simultaneously. A large downwelling Kelvin wave, triggered by record-breaking westerly wind bursts in April, has been propagating eastward across the equatorial Pacific. Subsurface ocean temperatures in that wave are running up to eight degrees above normal at depths of fifty to two hundred and fifty metres. As that warm water surfaces along the South American coast, it is pushing sea surface temperatures in the far eastern Pacific to extraordinary levels.

El Nino is emerging. Not a mild one. An 80 to 97 percent probability of it persisting through the rest of 2026 and into early 2027. The World Meteorological Organisation has already put out alerts. India's own IMD has revised the seasonal forecast downward to around 90 percent of the long period average, placing 2026 firmly in the below-normal category before the monsoon has even covered half the country.

El Nino does not affect India's monsoon through magic. It affects it through a very specific, well-understood mechanism. It disrupts the Walker Circulation, the large-scale atmospheric overturning that runs east to west across the tropics. When that circulation weakens, a chain of consequences follows, and one of the most critical links in that chain is a jet stream you have probably never heard of.

The Somali Jet: The Monsoon's Engine

The Somali Jet, also called the Findlater Jet or the East African Low Level Jet, is the actual fuel line of the Indian summer monsoon. It originates near Mauritius and the northern tip of Madagascar in the Southern Hemisphere. It crosses the equator near the Somali coast, deflects rightward as the Earth's rotation pulls it, and shoots across the Arabian Sea as a narrow, powerful river of low-level air carrying enormous quantities of moisture.

When it is strong, western India drowns. When it weakens, India waits.

El Nino weakens it. This is established science, confirmed across decades of reanalysis data. During El Nino conditions, the Indian Ocean develops easterly wind anomalies that directly dampen the Somali Jet's cross-equatorial flow. The jet loses speed. The moisture it carries depletes. The fuel line runs lean.

Here is what makes 2026 particularly concerning: recent research published in Climate Dynamics shows that under greenhouse warming, the El Nino and Somali Jet connection is strengthening. The teleconnection that was always there is becoming more powerful. A given strength of El Nino today suppresses the Somali Jet more than the same El Nino would have fifty years ago.

So we have a developing, potentially strong El Nino. An atmospheric system that is increasingly sensitive to it. And a Southern Ocean that is running quieter than usual in the sectors that normally help energise the cross-equatorial flow.

The Heat That Does Not Help

Step outside in Thane or Delhi or Nagpur right now. The temperatures are sitting at 40 to 50 degrees Celsius across large parts of the subcontinent. This is not normal summer heat. This is sustained, relentless, punishing heat that has been building for weeks.

Intuitively you would think: more heat, stronger monsoon. The logic seems obvious. The land is so hot, surely the pressure gradient between the ocean and the continent must be enormous. Surely the Somali Jet is being pulled in with tremendous force.

And that pull is real. The heat low over India does deepen. Surface pressure drops. Air rushes in at the surface while hot air rises and diverges at altitude.

But here is the cruel feedback of this particular season. The air rushing in is not coming in cool and moisture-laden from a well-energised southern Indian Ocean. It is coming in warm, partially depleted, carried by a Somali Jet that El Nino has already weakened. The moisture content is not high enough for the convective systems to organise and sustain themselves. Rain falls in patches, unevenly. The latent heat release that normally cools the surface and shifts the system into sustained monsoon mode... does not happen at scale.

The heat low deepens. More dry air rushes in. Temperatures stay elevated. The cycle resists breaking.

Mumbai will get its onset, perhaps by June 10 or 11, close to the normal date given the advance that was already into parts of Maharashtra by June 6. IMD will announce it. There will be relief showers. But proper, sustained monsoon... July and August will be the real test, and those months are when El Nino will be at or near its peak. The break periods between active spells will be longer. The troughs that organise heavy rainfall will be less frequent. Parts of the Deccan, central India, and the north-west will feel it acutely.

What East Africa Is Telling Us

One of the most reliable ways to read the Indian monsoon's health is to look at what is happening on the other end of the Somali Jet. When the jet weakens and fails to efficiently carry moisture across the Arabian Sea to India, that moisture does not vanish. It lingers. It contributes to convective instability near the East African coast instead.

Kenya has been flooding since March. The ITCZ has been sitting over equatorial East Africa with unusual persistence. Thunderstorm activity along the Somali coast and into Ethiopia has been elevated. This is exactly what the circulation theory predicts: a weakened Somali Jet means more convective energy stays near the source rather than shooting efficiently to the delivery point.

El Nino's effects on East Africa and India are almost mirror images of each other. Kenya floods while India waits. The moisture that should have crossed the Arabian Sea is spending too long near its origin, generating storms over the Rift Valley instead of reaching the Western Ghats.

When you see Kenya flooding in June, you should already be adjusting your expectations for India's July.

What the Earthquake Taught Me, Even Though It Was Wrong

I started this morning asking whether a 7.8 magnitude earthquake in the Philippines could affect India's monsoon. The answer, after several hours of following the thread, is no, not in any physically defensible way. The seismic event is separated from the Arabian Sea by the entire Indian subcontinent and belongs to a different ocean basin entirely. The mechanism simply does not exist.

But the question was not useless. It was the door.

Because sitting with that question, following its logic, looking at the wind maps, comparing this June to last June, led to a genuinely interesting set of observations. The quiet Southern Ocean. The SAM at a thousand-year extreme. The South Pacific's two record-low cyclone seasons in a row. The El Nino strengthening its grip on the Somali Jet faster than historical relationships would predict. The heat feedback loop over India. The flooding in Kenya as a mirror signal.

None of that insight came from already knowing the answer. It came from asking a wrong question seriously and following where it went.

On Reading the World

There is a habit that separates curious people from merely informed ones. It is the reflex of looking twice. Of not accepting the first layer of a story and scrolling on. Of asking what else this event might mean, what it connects to, what it contradicts, what it quietly confirms.

The earthquake was news. The monsoon was news. The El Nino was news. The flooding in Kenya was news. Each one sat in a separate tab, on a separate channel, filed under a separate category of concern.

But the world does not organise itself by category. It runs on physical laws that do not care about our filing systems. The Southern Ocean talks to the equatorial Pacific which talks to the Somali coast which talks to the Western Ghats which talks to the heat sitting over the Deccan plateau. Everything is talking to everything else, all the time.

The tragedy in Mindanao was real and deserved its moment of attention. But it also deserved the second question, the third angle, the look at the wind map after reading the death toll. Not because the earthquake and the monsoon are connected in the way I first imagined. But because the habit of looking for connection, of refusing to treat events as isolated, of asking why things happen rather than merely noting that they did... that habit is what makes the world legible.

The monsoon this year will be lean. The heat that preceded it was extraordinary. The Southern Ocean is quieter than it has been in living memory. El Nino is tightening its grip on the Somali Jet in ways that are intensifying with climate change. Kenya is flooded while Mumbai waits.

All of this is one story, told in different languages simultaneously. You just have to be willing to read all of them at once.

That is the only real skill worth developing, honestly. Not meteorology, not climate science, not geophysics. Just the willingness to keep asking why until something real and unexpected appears.

Because it always does. Sooner or later, it always does.
