Our final updates have been posted to the Climate.gov website, and this will be our final post to our social media channels.

Long-term trends in first leaf and first bloom dates across the U.S. are responding to long-term changes in temperatures. However, the trend across the Southeast may be surprising to some.

Extreme heat is worsening around the world and the stakes for heat safety are higher now than ever. Heat-related incidents at outdoor events are forcing the private and public sectors to confront the growing challenge of heat governance.

June 21 is Show Your Stripes Day—a time to spark conversation about how our world is warming.

This video shows how @noaa.gov temperature data for the U.S. is turned into the iconic stripes visualizations you may see shared today and tomorrow.

Line graph showing observed and predicted temperatures in the key ENSO-monitoring region of the tropical Pacific from spring 2025 through the fall. By late summer, the shading spans from El Niño to La Niña, showing the range of potential ENSO states. However, the majority of model forecasts are concentrated in the neutral range, meaning the highest chance is that the temperature in the Niño-3.4 region of the tropical Pacific will be near average.

ENSO-neutral conditions are expected to continue through summer.

While the odds of La Niña increase through the fall, the odds of neutral conditions continuing slightly outweigh those of La Niña.

🍃These maps compare this year's leaf-out dates to the first bloom dates. Several areas were in sync. What was extremely rare was the combination of early leaves but late blooms. 💮

Can you find a good example? Let us know in the comments!

Map pair titled "March 14-15 tornado outbreak: overlap of favorable conditions." First map shows accumulated convective precipitation, and the second map shows extremes in rotating updraft potential and instability. Both maps show tornado locations with red dots.

Tornado activity to date has been above average. How does La Niña make tornado-friendly weather more likely? Our guest blogger explains: www.climate.gov/news-feature...

A person resting on a hot day. The text says, “Protect yourself from heat and sun. Drink plenty of water and avoid alcohol. Beverages with electrolytes can also help protect against heat stress. Apply sunscreen (SPF 30 or higher) every two hours. Wear lightweight, loose-fitting, and light-colored clothing. Take regular breaks in the shade.”

Sunburns not only increase your risk of skin cancer but also increase your risk of heat-related illness and dehydration. On #DontFryDay, learn how to protect your skin by finding shade and wearing protective clothing.

A hiker standing at the top of a mountain. A quote from Sabrina of Lake Tahoe, CA, 1991 says, "I decided to hike Mt. Tallac, 10 miles, often running. I chose to hike alone, without water, and I did not check the weather. When I returned I was clammy, shaking, ash gray, and had a splitting headache and felt nauseous. It took over a day to recover. Don't be lazy. Always have plenty of water."

Traveling this summer? Make sure you know heat risk where you're traveling and how to stay safe during travel activities, such as hiking and going to the beach. Stay hydrated, and check on your travel partners.

An adult checking on a child in the backseat of a car. The text says, “Don’t forget anyone in a hot car. Everyone operates on auto-pilot once in a while. Have a plan! Place a bag or other item in the backseat to remind you of passengers after you park. Place a stuffed animal in the front seat as a reminder to check for passengers. Consider additional methods, such as phone alarms, partner/buddy check-ins, or built-in car reminder systems.”

One in four hot car deaths happens when a child gets trapped in a locked vehicle and experiences heat stroke. Even on a cool day, a car’s temperature can become deadly in minutes. Lock your vehicle doors, and keep keys out of reach.🔒 bit.ly/3UGH1gI

Atmospheric signs of this past winter’s La Niña continue to weaken. As the tropics settle into ENSO-neutral territory, other patterns have a chance of influencing seasonal climate. Will La Niña re-emerge? Our blogger breaks down the odds. Read more: www.climate.gov/news-feature...

NOAA’s climate outlook for May leans toward well above average temperatures across much of the North and East, dryness around the Great Lakes, and soggier-than-average conditions in the Southern Plains. Read more: www.climate.gov/news-feature...

Two graphs with the title "Mean daily surface temperature during 2024." One graph shows temperature from January 2024 through January 2025 near the Galapagos, while the second graph shows the same data near Washington D.C. The graphs show the average climatology in a black line, with variations above in red and below in blue.

Climate is the average of weather, but that’s not the whole story. Otherwise, how would we explain the differences in these two graphs? Our ENSO blog explains:
