Record US summer heat expected amid El Niño, drought
window 24h
IN SHORT
The United States is bracing for a potentially record-breaking summer heatwave, with forecasters citing the influence of El Niño and widespread drought across 45 states. The eastern US may see temperatures approach all-time highs, while the West faces heightened wildfire risks due to severe drought. Meanwhile, scientists fear El Niño could worsen a significant seabird die-off along the California coast, already struggling with depleted food sources from a marine heatwave. Singapore also warns of severe haze in August and September, anticipating increased transboundary smoke from regional fires exacerbated by El Niño.

Key facts
Forecasters warn of a potentially record-breaking US summer heatwave.
El Niño and widespread drought are expected to intensify the heat.
Drought conditions affect 45 US states.
Temperatures may approach all-time highs in the eastern US.
The western US faces severe drought and increased wildfire risk.
Scientists fear El Niño could worsen a seabird die-off along the California coast.
A prolonged marine heatwave has already depleted food sources for seabirds.
Singapore warns of severe haze in August and September.
El Niño is expected to increase the risk of transboundary smoke haze from regional fires.
Forecasters are warning of a potentially record-breaking summer heatwave across the United States, with El Niño and widespread drought contributing to the severe weather outlook. Approximately 45 states are currently affected by drought conditions, which are expected to intensify the heat. Temperatures are projected to approach all-time highs in the eastern United States. In the western US, the severe drought conditions are increasing the risk of wildfires.
Beyond the immediate heat and drought concerns, scientists are expressing apprehension about the potential impact of El Niño on marine ecosystems. Along the California coast, a significant seabird die-off is already underway, attributed to a prolonged marine heatwave that has depleted essential food sources. Experts fear that the onset of El Niño could exacerbate this crisis, leading to further starvation among various seabird species.
In Southeast Asia, Singapore's National Environment Agency (NEA) has issued a warning regarding potentially severe haze in August and September. This forecast is linked to the anticipated effects of El Niño, which is expected to increase the risk of transboundary smoke haze originating from land and forest fires in the surrounding region.
The confluence of these El Niño-related phenomena highlights a global pattern of intensified weather events and environmental stress. The US heatwave and drought, the seabird die-off in California, and the potential haze in Singapore all point to the far-reaching consequences of this climate pattern.

Frequently asked questions
El Niño is a climate phenomenon that occurs when sea surface temperatures in the central and eastern Pacific Ocean rise. It can release stored heat, acting as an accelerant for global temperatures and influencing weather patterns worldwide, often leading to warmer and drier conditions in some regions and wetter in others.
The primary concerns include extreme heat posing health risks, particularly to vulnerable populations, increased wildfire danger due to drought and low snowpack, potential water shortages impacting hydropower, and poor air quality from wildfire smoke.
Evidence suggests that human-caused climate change is accelerating, increasing the odds of severe weather events. A recent study found that the European heatwave was 'virtually impossible' without the influence of climate change, indicating a similar link for US heat events.
What Happens Next
01Temperatures are expected to approach all-time highs over the 4 July holiday weekend.
02Water levels in the Colorado River could fall below critical thresholds later this summer.
03El Niño is expected to boost global temperatures to new record highs over the next 12 to 18 months.
