It gets nowhere near as hot or as cold as most of the US. It is like most northern European coastal countries...maybe negative temperatures in winter, maybe 29 degrees on the hottest day in summer...the only months where the weather is really different are July and late December/January. Weather is pretty much the same all year round apart from that (just to be clear, I live in a coastal area close to the Netherlands).
The non-coastal regions of the US are more like Eastern Europe where you can get 35 degrees in the summer and -20 in the winter.
Have you seen it for practically a month straight? 40 degrees is average high in Las Vegas from June to September, and it’s only getting below 30 degrees from November to March. In Houston, Atlanta, Miami or New Orleans, it’s above 30 from May to October, and it’s even worse than in Vegas, because these places are much more humid, making the heat less bearable, as sweating doesn’t really cool you off.
Seriously, climate in Netherlands is in no way comparable to most of US.
