Assam Weather, AQI and Fuel Prices

Why Check Assam Weather & Data?

Assam runs a smaller economy than India's giants, roughly ₹6.43 lakh crore in the 2024-25 estimate, but it carries outsized weight in two industries. The state alone produced 687.76 million kg of tea in 2025, just over half of India's entire national output, and its oilfields around Digboi and Duliajan, home to state-run Oil India Limited, account for roughly a quarter of the country's onshore crude production. Both industries, and the roughly 3.6 crore people who live alongside them, sit on the banks of the same river that defines the state's biggest risk: the Brahmaputra floods almost every monsoon, and a bad year can submerge tea gardens in Dibrugarh and Sonitpur, cut off oilfield access roads near Duliajan, and force hundreds of thousands of people out of riverside villages known as chars. This page's live weather, AQI and fuel numbers matter differently depending on who's reading them: a tea garden manager in Jorhat watching the river gauge before plucking season, a Duliajan oilfield worker checking whether the approach road is still passable after heavy rain, a Guwahati commuter deciding whether Fancy Bazar will flood again this evening, a char-dwelling farmer weighing whether to move livestock to higher ground tonight.

The Brahmaputra's Floods, the Hills' Landslides: Assam's Two Real Risks

Assam's defining risk is the Brahmaputra itself, which floods parts of the state almost every year between June and September. The Assam State Disaster Management Authority's own decade-long tally counts 2022 as the worst flood year since 2016: 181 deaths across three separate waves that hit 35 districts and affected more than 9 million people, Barpeta alone counting over a million people affected and Dhubri more than 775,000 (the Union government gave Parliament a considerably higher toll for that same year, 278, a gap that has never been publicly reconciled). Flooding returned hard in June-July 2024, killing at least 109 people and inundating 1,325 villages across 19 districts, worst in Karimganj, Darrang and Tamulpur; the Brahmaputra's swollen waters also flooded Kaziranga National Park, killing more than 200 wild animals including 10 endangered rhinos. A smaller but real secondary risk sits in the hill districts, Dima Hasao, Kamrup Metropolitan and Cachar among them, where landslides killed 11 people in 2020 and 7 more in 2025.

How to Use Assam's Data for Daily Decisions

Tea garden managers and workers in Dibrugarh, Sonitpur and Jorhat should track river gauge levels through the June-September plucking season, since a Brahmaputra or tributary breach can submerge low-lying gardens within a day and halt harvest labour for weeks. Oil and gas workers around Duliajan and Digboi should check road-access advisories alongside rainfall totals, since flooded approach roads have repeatedly cut off oilfield sites during the heaviest monsoon bursts. Farmers on the Brahmaputra's char river-island settlements should treat any river level crossing the danger mark as a signal to move livestock and stored grain immediately, rather than wait for a formal evacuation order that can arrive too late for low-lying chars. Guwahati commuters should check the rain forecast before travelling through Fancy Bazar and other chronically waterlogged low points, where even a moderate downpour floods streets within the hour. Anyone booking a Kaziranga safari should confirm the park is open before travelling, since flooding forces closures through the monsoon months most years.

Assam's Seasonal Calendar

The southwest monsoon typically reaches Assam by late May or the first days of June, among the earliest onsets anywhere in India, and holds through September; the flood season's worst weeks usually cluster in late June and July, when heavy upstream rainfall in Arunachal Pradesh and Bhutan pushes the Brahmaputra and its tributaries over their banks downstream. Winter, November to February, is Assam's driest and most stable stretch, and the season most travellers and outdoor events favour. The Ambubachi Mela at Guwahati's Kamakhya Temple each June draws large crowds right as the flood season is beginning, worth checking river advisories before travelling. Kaziranga National Park closes to visitors for the monsoon months most years, reopening only once floodwaters recede, so safari trips are best booked for the November-April dry season instead. Bohag Bihu in mid-April, Assam's biggest festival and its agricultural new year, falls safely ahead of the flood season, though anyone travelling for it should still confirm early pre-monsoon showers haven't already disrupted rural roads.

Assam vs Comparable States: Weather & Data Comparison

Figures from state economic surveys, ASDMA/government disaster data and dated news reports; West Bengal is Assam's only real neighbouring state already published on this site, Bihar is included for its comparable river-flood profile rather than a shared border. Treat this as a broad reference, not a single-source dataset.
