The classic meteorological bamboozle! In the Netherlands, they're experiencing a bizarre temperature gradient where inland areas get nearly twice as hot as coastal regions. This is textbook coastal moderation effect - oceans have higher specific heat capacity than land, meaning they absorb and release heat more slowly. Meanwhile, inland areas heat up faster without that sweet maritime buffer. The split-screen perfectly captures the duality: umbrella-clutching misery inland versus beach-ready bliss at the coast, despite being in the same tiny country! The Dutch are experiencing microclimates on steroids. Next time someone says "it's not the heat, it's the humidity," just show them this geographical temperature prank.
