The Highest Temperature in the US Every June Since 1950

Last year, 2023, was the warmest year yet, according to data. While climate change may seem subtle to some, each degree that ticks upward affects our environment. Per data from the National Centers for Environmental Information, it has been 47 years since we have seen a cooler-than-average year. As the Earth continues warming up, what happens within the next century will depend on the fossil fuel, greenhouse gases, and carbon dioxide continuously pumped into our air. Regarding the summer months, June tends to have the lowest temperature. The highest temperature every June since 1950 shows a mean of 81.3°F.

As we look at the National Centers for Environmental Information data, we can see a slight uptick in June's highest temperature in recent years.

To collect the data for the highest temperature every June since 1950, 24/7 Tempo consulted the data from the National Centers for Environmental Information. The information includes the highest temperature and each year's anomaly from the mean. (After this article, read our list of popular travel destinations that may be gone in the next decade.)

Global mapping of the Earth's temperature has become a valuable tool. It allows scientists to record various temperatures around the globe and track how these temperatures change from year to year. These measurements are called temperature anomalies and give scientists a snapshot of how the temperature changes from the median each year. If a value is missing, scientists will estimate them. Lastly, the global temperature average is then calculated.

According to data, the Earth's temperature has been on the rise every decade since 1850. The average rise is 0.11°F. Additionally, the rate at which the average Earth temperature rises has increased to three times faster since 1982. Furthermore, the warmest year since the global temperatures were recorded was 2023.

Although 0.11 degrees may not seem like a considerable jump, this increase can significantly affect the Earth. As the snow and sea ice melt, heavy rain falls accumulate, and the temperatures reach new highs, the habitat for many animals and plants changes. The trend has shown the global temperature increase has grown faster over the last 30 years, with 2023 being the warmest year recorded.
