Better understand the weather with our explanations of weather phenomena, measurements and terms that help you choose the right clothing.
A warm afternoon can become a chilly evening faster than you expect. Radiative cooling after sunset happens at different rates depending on cloud cover and humidity.
A 60% chance of rain doesn't mean it will rain 60% of the time. Here's what rain probability actually tells you and when it should change what you wear.
The difference between drizzle and a downpour isn't just about getting wet. Rainfall intensity in mm per hour changes how quickly clothing fails as insulation.
20°C sounds like it should be comfortable. And often it is. But add enough wind or cloud cover and it stops feeling that way fairly quickly.
The thermometer reading is measured in shade, at a standard height, in a sheltered housing. It doesn't reflect how you actually stand outside. Here's everything else that matters.
Weather apps often show a day's maximum temperature, but that maximum doesn't arrive until mid-afternoon. Here's how temperature changes through the day and why it matters for getting dressed.
You're sitting in the sun, perfectly comfortable. A cloud passes. Suddenly you're crossing your arms. The air temperature hasn't changed at all.
Humidity works in both directions: it makes hot days feel suffocating and cold days feel more biting. Here's what's actually happening and why KorteBroekAan.nl includes it.
The same thermometer reading feels completely different under a clear sky versus a grey one. Cloud cover changes how much solar radiation actually reaches you.
15°C in full sun, no wind, a sheltered bench. It feels genuinely pleasant. Here's the physics of why solar radiation adds warmth the thermometer doesn't measure.
UV radiation is invisible and painless until it isn't. Here's what the UV index actually measures, how fast fair skin burns at different levels, and why it's relevant beyond sunscreen.
The app said 18°C and pleasant. You're outside in five minutes and you're cold. Or the reverse. Here's why that gap exists and what to do about it.
The Beaufort scale gives wind a number, but what does each level actually feel like on your body? Here's how wind force translates to real temperature differences.
Wind makes more difference to what you wear than the temperature itself. Here's how windchill works, when it actually matters, and how KorteBroekAan.nl accounts for it.
13°C and grey in the morning, 21°C in full sun by afternoon, showers in the evening. There's no single right answer. The solution is layers, used deliberately.
15°C in April after a cold winter feels like liberation. The same temperature in September feels like summer is over. Both reactions make complete sense.
Getting soaked at 14°C and suddenly feeling cold isn't just discomfort. Wet clothing conducts heat away from your body dramatically faster than dry clothing.
The thermometer reads 18°C but you still feel cold. How is that possible? We explain what feels-like temperature is, how it is calculated, and why KorteBroekAan.nl uses it.
Two days, both 14°C. One needs a jacket, the other just a light shirt. The difference is direct solar radiation, and it matters more than most weather apps let on.
Drizzle looks harmless and often is, until it isn't. The difference between fine rain and heavy showers goes beyond wetness rates.
