A climate researcher is advising caution for Finnish travelers heading to Southern and Western Europe this summer. The approaching El Niño weather pattern is expected to contribute to extreme weather events globally, including potentially severe heatwaves across popular tourist destinations. While Finland is anticipated to experience minimal impact from El Niño, Western and Southern Europe could face significant heat. Long-term forecasting accuracy related to El Niño’s effects remains limited, according to the Finnish Meteorological Institute. Travelers are urged to be prepared for unusually high temperatures. The researcher suggests considering the risks before traveling to affected areas.
