Global ocean temperatures hit a record high for June, according to the latest Copernicus Climate Change Service & Copernicus Marine Service data. Over the past three years, oceans outside the polar regions have been 0.35–0.73°C warmer than average. El Niño pushed June to a new record.

In 2014, WMO asked weather presenters to imagine a report from the year 2050. A mere 12 years later, these possible scenarios grounded in climate science are already a reality in some parts of the world as we're seeing in Europe. Watch the series ▶️ bit.ly/4eQUVW3

In May 2026, Europe experienced a rapid climate transition from cooler-than-average conditions to an unusually early & intense heatwave. France, UK, Ireland, Portugal saw their highest May temperatures on record, according to Copernicus Climate Change Service’s latest bulletin: http://bit.ly/4ek0T1L

The oceans are vital to weather forecasting and climate prediction. Here are 5 reasons why: 1️⃣ Your 7-day weather forecast depends on ocean observations. Observations provide data on sea surface temperature, ocean heat content, as well as waves and sea ice.

For June–August 2026, WMO forecasts indicate significant shifts in rainfall patterns—a classic atmospheric response to the developing Pacific El Niño. See which regions are likely to experience below-normal, normal or above-normal rainfall: https://bit.ly/4uhbDDR

All life on Earth depends on the climate system. By observing its signals, we better understand our changing world, improve forecasts, and safeguard our planet. #NowForClimate: 24/7 global observations must be reliable, consistent, and accessible. #WorldEnvironmentDay

The WMO community will be carefully monitoring El Niño conditions in the coming months. Advance seasonal forecasts and #EarlyWarnings are vital to save lives and cushion the impact on our economies and our communities. WMO El Niño/La Niña Update 🔗bit.ly/4e1hvLt

An El Niño is emerging. What do you know about it? El Niño is a powerful natural climate pattern that warms ocean waters in the central and eastern Equatorial Pacific. It typically occurs every 2-7 years, but no two El Niños are exactly alike. More ➡️ bit.ly/4e1hvLt

Watch United Nations Secretary-General António Guterres' message about the emerging El Niño that is set to influence global temperature and rainfall patterns, increasing the risk of extreme weather in the coming months. More information ➡️ http://bit.ly/4e1hvLt

🆕 WMO confirms: El Niño conditions are developing and are set to influence global temperature and rainfall patterns, increasing the risk of extreme weather over the coming months. Most forecast models suggest it will be at least moderate – possibly strong. Be prepared. More info➡️ bit.ly/4e1hvLt
