The cooling is here, but the greatest heat bill is yet to come. The year 2027 could break all records.

The article discusses the recent cooling trend following an intense heatwave in Slovenia, noting that while temperatures have dropped, the effects of this summer’s extreme heat will persist for months. It highlights that the summer was approximately 2.8°C warmer than the average for the period 1991–2020, making it one of the hottest on record. The highest temperature recorded was 40.1°C in Koper, close to the national record set in 2013. Climate scientist Gregor Vertačnik from the Slovenian Environment Agency warns that 2027 could be one of the hottest years in history due to a strong El Niño event, which typically peaks several months later. While Slovenia may not experience another severe drought immediately, the report emphasizes the increasing risk of climate-related impacts and the need for preparation. The article also notes the significant agricultural losses, including reduced crop yields and early forest discoloration, underscoring the broader environmental and economic consequences of rising temperatures.

Slovenia's summer of 2026 has set new records for heat, marking the hottest meteorological summer since measurements began in 1950. According to data from the Agency for Environment (Arso), all three months of the summer were significantly warmer than average, with August recording a deviation of 3.7 degrees Celsius above the reference period of 1991–2020. This makes August the warmest month in Slovenia at least since 1950. Over the course of the three-month summer, the national temperature deviation reached 2.8 degrees Celsius, the highest recorded since 1950. The agency noted that particularly hot afternoons contributed most to this record-breaking heatwave. The previous record for temperature deviation was 2.4 degrees Celsius, achieved in the summers of 2003 and 2024. For comparison, the coolest summer in terms of temperature deviation was 1978, which had a deviation of around three degrees below the reference period. Since the 1970s, summers in Slovenia have been warming steadily, with temperatures rising by approximately four degrees Celsius compared to the 1953–1991 period. In recent years, the last twelve summers have been consistently warmer than any before them in that timeframe. This summer was also the sunniest since at least 1960, with sunlight shining for nearly 880 hours nationwide. Solar radiation has increased by about 20 percent since the 1970s, according to Arso. Despite this increase, rainfall levels were notably low, placing this summer among the seventh driest since 1950. Parts of southeastern Slovenia experienced record drought conditions. Although total precipitation was not exceptionally low across the country, a severe drought affected much of Slovenia from mid-July to mid-August due to a lack of rain during the central part of the summer, prolonged heat, and predominantly sunny weather. Another notable observation is that for the first time in recorded history, there was no measurable snow cover at Kredarica throughout the entire summer. A long-term trend in decreasing summer rainfall has been observed since the 1970s, with a reduction of about 18 percent over the past few decades. However, despite this trend, the year 2023 saw the wettest summer since 1950. The summer was marked by two distinct and prolonged heatwaves: one ending in late June and another spanning late July through early August. During the first heatwave, a new June temperature record was set in Podnanos in the Vipava Valley, reaching 38.7 degrees Celsius on June 29. The second heatwave saw the highest measured temperature of 40.1 degrees Celsius recorded on August 2 at the Koper Markovec station. On July 31, Dolenje near Ajdovščina recorded 39.9 degrees Celsius, just a tenth of a degree less. In the interior of Slovenia, the hottest spot was Marinči village near the Krka River, where temperatures reached 39.6 degrees Celsius on August 4. At numerous measurement stations, the number of very hot days, those exceeding 30 degrees Celsius, was the highest ever recorded. In Rateče, temperatures reached at least 30 degrees Celsius on 25 days, while in Ljubljana, such days numbered 57. In Dobliči near Črnomlje, there were 63 days above 30 degrees, and in Bilje near Nova Gorica, a record 69 days. In Ljubljana, temperatures exceeded 35 degrees Celsius on 15 days, in Dobliči on 21 days, and in Bilje on 28 days, all surpassing previous records significantly. According to Arso, the most significant contributor to these statistics was an exceptionally strong and prolonged heatwave. The heatwave led to widespread drought conditions, affecting groundwater levels across almost the entire country by late August. Severe drought conditions were present in several regions, including Bohinj, Inner Carniola, Ljubljana, Kočevska, Lower Styria, White Carniola, Lower Savinja, Carinthia, and Pomur. Moderate drought conditions were observed in most other regions, while normal water levels were maintained in the Gorizia region. The current drought is not unprecedented, but data indicates that the frequency of hydrological droughts has increased in recent decades. Between 1981 and 2025, eight of the ten driest years occurred after 2000. Natural disasters related to drought were declared in 2003, 2006, 2007, 2012, 2013, 2017, 2022, and 2025. Among the most extensive droughts were those in 2003, 2012, 2013, 2017, and 2022. Analysis of agricultural drought shows that periods of intense water shortage are becoming more frequent and severe, affecting areas and times of the year where drought previously was not as pronounced. A distinctive feature of modern droughts is their rapid onset and development, often occurring quickly during heatwaves. River flows were generally below average this year, with July being the driest month, showing significantly lower monthly averages than the long-term average on all rivers. Similar conditions were observed in 2022, 2013, and especially in 2003. Some river flows were even record-low, with the Mur River in Upper Radgons having lower monthly flows this summer than in the drought year of 2003. The heatwave and associated drought have had significant impacts on agriculture, with reports of reduced crop yields and damage to forests. Farmers have already begun reducing livestock numbers due to the effects of the drought. These impacts will continue well into the coming months. Climate scientists warn that the effects of the current heatwave may be followed by even hotter conditions in the future. Climate scientist Gregor Vertačnik from Arso noted that the year 2027 could potentially become the hottest year on record due to the influence of a strong El Niño phenomenon, which typically raises global temperatures by several tenths of a degree. With the ongoing long-term warming trend, the impact of El Niño could lead to even higher temperatures in the coming years. As the meteorological summer comes to an end, the effects of its extreme heat and drought will linger, influencing both the environment and human activities for months to come.
