A medida que las temperaturas globales siguen aumentando, las olas de calor, un asesino silencioso y mortal, se están volviendo más extremas.

Abordar la creciente amenaza global de las olas de calor es una prioridad para la IFRC.

[Dylan Winder, IFRC @DylanWinderIFRC]

The 5th edition of Heat Action Day, initiated by @IFRC, brings communities together worldwide to tackle extreme heat.

This year's theme, indoor heat, puts the spotlight on the health risks people face inside their homes, schools, workplaces, and care facilities.

Today is Heat Action Day.

As global temperatures continue to rise, heatwaves, an already silent and deadly killer, are becoming more extreme. Addressing the rising global threat of heatwaves is a priority for the @IFRC.

As the IFRC continues to prepare and adapt communities to this already changing climate,
we call on world leaders to take decisive action to protect vulnerable communities worldwide.

We all have a role to play. Join us, and let’s beat the heat together.

Today is Heat Action Day. Rising extreme heat is a threat to people and the planet.

Through its Global Climate Resilience Platform, the @IFRC aims to protect 100M people in 100 cities, with a target of mobilizing CHF 500M to address extreme heat where it strikes hardest by 2030.

This Heat Action Day, we are reminded that simple actions can save lives.

When temperatures rise, staying hydrated, finding cooler spaces, and checking on those most at risk can help prevent heat-related illness.

Red Cross and Red Crescent volunteers across Africa continue to support communities with practical steps to stay safe. #HeatActionDay2026

Heat Action Day bring communities together worldwide to tackle the growing threat of extreme heat. This year's theme, indoor heat, puts the spotlight on the health risks people face inside their homes, schools, workplaces, and care facilities.

As the organization that created Heat Action Day, the @IFRC each year encourages people to take concrete action to prevent heat related illness and death.

Here are some life-saving tips to protect yourself and others from indoor heat. #BeatTheHeat

Today is #HeatActionDay.

Across Sudan, extreme heat is placing additional pressure on communities already facing difficult conditions, especially the most vulnerable, as temperatures rise to up to 45°C in some regions.

With @IFRC support, @SRCS_SD volunteers are working with communities to strengthen climate resilience and share simple ways to stay safe.

Stay hydrated, drink cool water where possible, and check on those most at risk.

And that’s a wrap for Heat Action Day 2026!

Led by the @IFRC network and partners, Heat Action Day mobilizes cities, communities, and organizations worldwide to take simple yet life-saving steps to protect people from heat-related illness.

This year, our teams and partners led creative, community-driven initiatives across the globe. For example, in Geneva, Switzerland, the iconic Jet d’Eau was lit up in orange to mark the day.

Thank you, @VilledeGeneve, for standing with us to #BeatTheHeat.

Let’s keep the momentum going.

Today is Heat Action Day, a global initiative led by the @IFRC to raise awareness and take action on the growing threat of extreme heat

More than 500,000 people die each year from heat-related causes, yet it remains a silent crisis.

Through the IFRC’s Extreme Heat Initiative, we are helping communities prepare for and adapt to extreme heat. Resources must reach local communities, and local actors must be empowered to lead. Governments, businesses and communities all have a role to play.

We can no longer afford to look away. Extreme heat is here, and it is deadly. Let’s act now and #BeatTheHeat together.

An exceptional and record-breaking spell of heat at the end of May helped to secure the warmest spring on record for England and Wales, and the third warmest for the UK, for mean temperature.

In 2025, temperatures in Latin America & the Caribbean were +0.4 °C hotter than average. But temperature does not rise equally everywhere nor across time.

Changing temperatures have cascading impacts on health, agriculture, energy demand & ecosystems. https://t.co/mF1aOExbfA

[World Meteorological Organization @WMO]

Global average temperatures are likely to continue at or near record levels in the next 5 years, with global temperatures predicted to reach about 1.3°C to 1.9°C above the 1850–1900 average, according to a new @WMO and @metoffice report.

Today, the @IFRC was pleased to co-host the launch of the Anticipation Hub’s flagship report, “Anticipatory Action in 2025: A global overview.”

The task now is clear: make anticipatory action a standard function of governance, embedded in national systems, financing structures and political decision-making.

The message is simple: early warnings only save lives when they lead to early action.

This is at the heart of the Early Warnings for All initiative, where IFRC leads on Pillar 4: preparedness to respond to warnings. We must move from early warning systems to early warning and early action systems.
