Summary
Esperanza Base on the northern Antarctic Peninsula logged 15.4C on June 6, the highest June temperature recorded there and a sharp winter-season anomaly.
The reading beat the previous June record of 13.3C set in 1998 and stood far above Esperanza's average June temperature of minus 6.2C.
Climate scientists told AFP the unusual warmth is already driving abnormally fast ice melt during the Antarctic winter.
The spike adds to evidence of extreme temperature swings on the Antarctic Peninsula, one of the continent's fastest-warming regions.

Record-Breaking June 2026 Antarctic Heatwave: Unprecedented Winter Temperatures and Global Implications
Overview
In June 2026, the Antarctic Peninsula faced an unprecedented heatwave, with Esperanza Base recording a remarkable 15.4°C—far above its usual June average of -6.2°C and breaking the previous 1998 record. This extreme warmth, confirmed by climate scientists, led to abnormal ice melting during what should be the coldest months. The heatwave lasted for three weeks with daily above-zero temperatures, causing large snow-free areas and highlighting the severity of the event. These record-breaking conditions signal significant changes in the region’s climate, underscoring the urgent need to understand and address the impacts of rapid warming in Antarctica.
