A four-month dry spell with above-normal heat is a crisis in slow motion.
Kenya stands at a threshold between flood and drought, a nation about to be tested by both extremes within the span of a single season. Through June 1, heavy rains will sweep across the Highlands, the Lake Victoria Basin, the Coast, and Northeastern Kenya, bringing with them the threat of flooding, violent winds, and dangerous temperature swings. Yet almost as soon as the deluge passes, a regional climate forecast warns of four months of below-normal rainfall and above-normal heat — conditions that echo the hardship of El Niño years past. For the pastoral and farming communities who live closest to the land, this is not merely a weather story; it is a story about survival.
- Kenya's meteorological department has issued urgent warnings for heavy rainfall, localized flooding, and winds exceeding 25 knots across multiple regions between May 26 and June 1.
- Coastal communities and Garissa County face the sharpest immediate danger, with flooding capable of severing transport links, halting fishing operations, and upending daily life.
- Temperature extremes compound the risk — highland nights dropping below 10°C while lowland afternoons surge past 30°C, stretching both people and infrastructure to their limits.
- Even as the rains fall, a longer shadow looms: a regional climate center has forecast drought and above-normal heat from June through September, echoing the devastating El Niño years of 1997 and 2023.
- Pastoral communities, rain-fed farmers, and hydropower systems across Kenya face a compounding crisis — a brief deluge followed by months of scarcity and heat stress threatening food security and livelihoods.
Kenya's weather service issued a warning this week that captures a painful paradox: the country is about to experience too much water and then, almost immediately, far too little. Beginning May 26, heavy rains will sweep across the Highlands on both sides of the Rift Valley, the Lake Victoria Basin, the Coast, and parts of Northeastern Kenya, lasting through June 1. Coastal regions and Garissa County face the gravest short-term risk, with rainfall intense enough to trigger localized flooding and disrupt transport, fishing, and outdoor work.
The weather will be volatile beyond the rain itself. Highland areas will see nighttime temperatures fall below 10°C, while lowland afternoons will push past 30°C. Winds exceeding 25 knots are expected across northwestern, northeastern, coastal, and southeastern lowlands — strong enough to disrupt marine activities and ground outdoor operations. Authorities have urged residents in vulnerable areas to stay alert and prepare for rapidly shifting conditions.
But the immediate storm is only the opening chapter. On May 21, the IGAD Climate Prediction and Applications Centre, presenting at the 73rd Greater Horn of Africa Climate Outlook Forum in Addis Ababa, released a forecast for June through September 2026 that offers little comfort. Much of Kenya — particularly western regions — is expected to receive below-normal rainfall during what should be a critical agricultural season, while temperatures run above average across the entire region.
The consequences of that combination are severe. Rain-fed agriculture will struggle, water supplies will dwindle, livestock productivity will fall, and food insecurity will deepen. Hydropower generation, dependent on seasonal rains to fill reservoirs, will suffer. Pastoral communities in Kenya's arid and semi-arid zones — whose livelihoods are built entirely around seasonal rains and the grazing they produce — will bear the heaviest burden. The forecast conditions resemble those of strong El Niño years, particularly 1997 and 2023, when the Greater Horn experienced widespread hardship. Kenya is bracing for a week of chaos, and then months of slow-burning crisis.
Kenya's weather service issued a stark warning this week: the country is about to be caught between two opposite extremes. For the next seven days, starting May 26, heavy rains will drench much of the nation. Then, almost immediately after, the rains will vanish for four months, leaving the land parched and hot.
The Kenya Meteorological Department mapped out where the deluge will hit. The Highlands on both sides of the Rift Valley will see sustained downpours. So will the Lake Victoria Basin, the South Rift Valley, the Coast, and scattered areas across Northeastern Kenya. The rainfall window runs through June 1. But the real danger lies in the intensity. Coastal regions and Garissa County face the prospect of heavy rainfall events severe enough to trigger localized flooding and disrupt daily life—transport networks, fishing operations, outdoor work all at risk.
The weather will be volatile in other ways too. In the high-altitude zones—the Highlands East of the Rift Valley, the Central Rift Valley, areas near Mount Kilimanjaro—nighttime temperatures will plummet below 10 degrees Celsius. Meanwhile, in the lowlands, daytime heat will soar past 30 degrees. Strong winds will add another layer of chaos. Across the northwestern, northeastern, coastal, and southeastern lowlands, winds are expected to exceed 25 knots, roughly 12.5 meters per second—fast enough to disrupt marine activities and ground outdoor operations. The meteorological department advised residents in vulnerable areas to stay alert, to watch for rapid shifts in conditions, to prepare for the worst.
But the immediate rainfall is only half the story. On May 21, a regional climate center released a longer forecast that painted a grimmer picture. The IGAD Climate Prediction and Applications Centre, presenting findings at the 73rd Greater Horn of Africa Climate Outlook Forum in Addis Ababa, warned that from June through September 2026—the critical rainy season for agriculture across the region—much of Kenya will receive below-normal rainfall. Western Kenya faces a likely dry spell. Coastal areas might see near-normal rains, but that offers only limited relief. Temperatures, meanwhile, will run above average across the entire region.
The combination is dangerous. Less rain plus more heat equals stress on rain-fed agriculture, dwindling water supplies, reduced livestock productivity, and deepening food insecurity. Public health systems will face strain. Hydropower generation, which depends on seasonal rainfall to fill reservoirs, will suffer. The pastoral communities scattered across Kenya's arid and semi-arid regions—already vulnerable to climate shocks—will be hit hardest. These are people whose livelihoods depend entirely on seasonal rains and the grass those rains produce. A four-month dry spell with above-normal heat is a crisis in slow motion.
The ICPAC comparison is instructive and unsettling. The expected conditions resemble what happened during strong El Niño years—specifically 1997 and 2023—when western Kenya and other parts of the Greater Horn experienced well-below-normal rainfall. Those years brought hardship. This forecast suggests similar conditions are coming. Kenya is bracing for a week of chaos followed by months of scarcity.

La Conversación del Hearth Otra perspectiva de la historia
So we have heavy rain coming this week, but then a drought after? That seems contradictory.
It's not really. The heavy rain is a short-term weather event—a system moving through. The drought forecast is a seasonal pattern for the next four months. They're separate phenomena. The rain this week won't refill the reservoirs or set up the soil moisture needed for the dry season ahead.
Who gets hurt most by this?
Pastoral communities in the arid regions. They depend on seasonal rains to feed their livestock. If those rains don't come and temperatures stay high, the grass dies, the animals starve, and families lose their primary source of income and food.
Is this connected to climate change, or is it just normal variability?
The forecast doesn't explicitly say. But the comparison to 1997 and 2023—both strong El Niño years—suggests this is a recognizable pattern. Whether it's becoming more frequent or intense is a separate question the forecast doesn't address.
What about cities? Will Nairobi be affected?
The forecast doesn't single out Nairobi specifically. But if water supplies drop and hydropower generation falls, cities will feel it too—through rationing, higher energy costs, pressure on public services.
What are people supposed to do with this information?
The immediate advice is to stay alert this week, prepare for flooding and strong winds if you're in a vulnerable area. Longer term, it's a signal to prepare for water scarcity and potential food shortages. Farmers and herders need to plan accordingly.
