Narrative updated. “Strong El Niño meets Uzbekistan's dry season — what it means for the autumn rains and harvest”
Uzbekistan's July–October window is its climatological dry season, so the measured +2.7°C temperature anomaly rather than any rainfall deficit is the dominant El Niño signal for the country. The WMO warns that El Niño could bring unusually heavy summer rains to Central Asia, while the European Commission's ASAP service has issued widespread crop warnings for the second half of the year. With the May–September growing season and August–October harvest on schedule, the main risks are heat stress on cotton and wheat and the timing of the autumn rains that recharge reservoirs and irrigation canals.
14.6 mm vs 2.7 mm normal — too little rain in this window for a % to mean anything
The July–October window is Uzbekistan's climatological dry season, so no meaningful rainfall percentage anomaly applies; the key question is whether El Niño shifts the onset of the autumn rains, with WMO guidance pointing to unusually heavy summer rainfall over Central Asia.
News source28.01°C mean vs 25.31°C normal
Measured mean temperatures for 9 July–6 October 2026 ran +2.7°C above normal, consistent with the strong El Niño (ONI +2.16) and with ASAP crop-warning forecasts for the second half of the year.
News sourceThe May–September growing season and the August–October harvest are proceeding on schedule, but the anomalous heat and the risk of unusually heavy late-summer rain could affect cotton and wheat quality at harvest.

Sector by sector
ASAP crop warnings for the second half of 2026 flag heat and erratic late-summer rainfall as risks to cotton and wheat yields during the ongoing harvest.
The dry-season window offers no rainfall relief, so irrigation demand for cotton and wheat is expected to draw down reservoirs ahead of the autumn rains.
Sustained heat of +2.7°C above normal raises the risk of heat stress, especially for outdoor agricultural workers, and may favour water- and vector-borne disease.
Above-normal temperatures are likely to lift summer electricity demand for cooling, while reduced hydropower inflows could tighten supply later in the year.
Warmer water temperatures and lower river flows in the Amu Darya and Syr Darya basins could stress inland fisheries and aquaculture during the peak heat.

2023-24
The most recent strong El Niño brought warmer-than-normal conditions to the region and reinforced the pattern of heat stress on summer crops and higher irrigation water demand.
unsourced background2015-16
A very strong El Niño contributed to anomalous warmth over Central Asia, with early snowmelt and reduced seasonal river flow affecting irrigation scheduling in Uzbekistan.
unsourced background1997-98
One of the strongest El Niño events on record coincided with hot, dry conditions across Central Asia, stressing irrigated cotton and wheat and lowering reservoir levels in the Amu Darya basin.
