Score moved 4 → 5 . “Record El Niño heat meets Serbia's driest stretch — will the autumn rains show up”
Global forecasters are calling the 2026 El Niño the strongest on record, with ONI values well past the +0.5 threshold and warnings of record-shattering weather worldwide. For Serbia the measured signal is more muted: rainfall from 9 July to 6 October 2026 ran 63% below the 1991–2020 normal while mean temperatures came in 2.9°C above normal. Because that window is climatologically Serbia's dry season, the real test is whether the coming autumn rains arrive on time to recharge soils ahead of winter wheat sowing.
64.8 mm vs 173.5 mm normal
Measured rainfall for 9 July–6 October 2026 was 63% below the 1991–2020 normal, though this window is climatologically Serbia's dry season, so the key question is whether the autumn rains arrive on time.
23.08°C mean vs 20.16°C normal
Mean temperature for the same window ran 2.9°C above normal, consistent with the record-strength El Niño signal described in the articles.
Spring planting and the May–September growing season proceeded on schedule, but the hot, dry late-summer window likely trimmed yields and left soils short of moisture for autumn sowing.

Sector by sector
Late-summer heat and a 63% rainfall deficit likely stressed maize and sunflower yields and left seedbeds dry for autumn wheat sowing.
Reservoir and river levels are expected to run below normal until the autumn rains recharge catchments, raising irrigation and navigation concerns.
Prolonged heat and dry conditions raise the risk of heat stress, dehydration and dust-related respiratory irritation, particularly among the elderly.
Above-normal temperatures likely lifted summer cooling demand while low river flows could constrain hydropower output on the Danube and Drina systems.
Warmer, lower rivers and canals likely reduced dissolved oxygen and stressed warm-water fish stocks through the late-summer period.

A very strong El Niño contributed to hot, dry summer conditions in Serbia, with reduced maize yields and lower Danube water levels.

One of the strongest El Niño events of the 20th century, associated with warm, dry summers across the Balkans and below-average regional river flows.
