Portugal is facing high temperatures, with some areas reaching 34°C and several districts under heat warnings. The Algarve region's water temperatures are also elevated, though not record-breaking. Last July was marked by significant marine heatwave activity, with 71% of the global ocean experiencing above-average temperatures. The Mediterranean Sea has reached unprecedented levels, with 95% showing above-average temperatures. While this may be enjoyable for beachgoers, rising sea temperatures pose threats to marine ecosystems and can lead to severe weather events.
