Narrative updated. “UN warns El Niño will peak in December — Macau's measured signal stays weak, but typhoon risk does not”
UN agencies warn that the current El Niño will intensify and peak around December 2026, with China facing a higher risk of super typhoons and the Panama Canal already cutting shipping because of drought. For Macau, however, the measured local signal is weak: rainfall for 9 July–6 October 2026 ran about 92% above the 1991–2020 normal, but that window is the climatological dry season when totals are normally under 20 mm, so the figure says little about the coming rains. Mean temperature over the same period was only about 0.5°C above normal, and the planting, monsoon and harvest calendar remains on schedule, leaving typhoon-driven disruption as the main local concern.
1343.9 mm vs 700.5 mm normal
Measured rainfall for 9 July–6 October 2026 ran about 92% above the 1991–2020 normal, though this window falls in Macau's climatological dry season when totals are normally under 20 mm, so the percentage is not a meaningful signal for the coming wet season.
28.86°C mean vs 28.39°C normal
Mean temperature for the same window came in about 0.5°C above normal, a modest warming consistent with the weak canonical El Niño signal for Macau rather than the extreme heat implied by global headlines.
The planting (Apr–May), summer monsoon (Jun–Aug) and harvest (Sep–Oct) calendar remains on schedule, with the main watch point being whether El Niño-enhanced typhoon activity disrupts the late harvest and the start of the next planting cycle.

Sector by sector
Planting, monsoon and harvest timing remain on schedule, but a December peak in El Niño could bring typhoon-driven crop damage and waterlogging to Macau's limited market-garden and imported fresh-produce supply chain.
Reservoir and storage levels are not under stress locally, though the Panama Canal drought cited in the articles is a reminder that El Niño-driven drought elsewhere can tighten regional water and supply logistics.
Warmer, wetter conditions raise the likelihood of mosquito-borne disease and heat stress, with storm-related injuries and post-typhoon water contamination as secondary concerns.
Higher typhoon risk implies elevated grid-damage and outage potential, while warmer-than-normal conditions could nudge summer cooling demand above typical levels.
Warmer coastal waters and stronger typhoon swells are expected to disrupt small-scale fishing and mariculture operations in the Pearl River estuary during the December peak.

A strong El Niño coincided with record global heat and an active western Pacific typhoon season, with Macau issuing multiple storm warnings and recording above-normal autumn rainfall.

One of the strongest El Niño events on record brought a late and erratic typhoon season to the Pearl River Delta, disrupting Macau's ferry and air links and pushing up food prices.
