Rainfall Finally Arrives, But Less Than Expected
June 18, 2023 – After enduring weeks of persistent drought, parts of the country will finally see some much-needed rain on Sunday. However, it seems that the rain radar may have overestimated the amount of precipitation. Meteorologist Johnny Willemsen from Weerplaza explains that the rain radar tends to exaggerate the forecast.
When checking the rain radar on Sunday, one can observe rain approaching from Belgium and Germany. This rainfall is desperately needed, as there has been a significant lack of rain since mid-May.
Nevertheless, the actual amount of rain that will reach Dutch soil is expected to be disappointing. This overestimation is due to the functioning of the rain radar itself.
Willemsen clarifies, “The radar’s range affects its accuracy. If the radar detects precipitation at a distance of 1.5 kilometers above the ground, half of it evaporates before reaching the surface. Therefore, less rain falls than what the radar indicates.”
The Rain Radar’s Optimism
While Sunday will not remain dry, the rain radar’s optimism regarding the quantity of rainfall is a letdown. This is particularly disheartening for nature, which has been longing for precipitation for weeks.
Weerplaza reports that the Netherlands is currently experiencing the longest period without rainfall in its history. Although the KNMI has not officially declared it as such, they acknowledge that the drought period is “exceptional.”
Fortunately, next week is expected to bring some relief. Weerplaza predicts rain and thunderstorms, primarily on Tuesday and Thursday. However, it is important to note that this does not signify a prolonged period of heavy rainfall, as emphasized by the weather service.

How does the rain radar’s tendency to exaggerate the forecast affect the amount of precipitation in Dutch soil?
As the much-anticipated rainfall finally arrives, it appears that the rain radar may have overestimated the amount of precipitation. Meteorologist Johnny Willemsen explains that the radar’s tendency to exaggerate the forecast is to blame for this disappointment. Although rain is approaching from neighboring countries, the actual amount expected to reach Dutch soil is expected to be underwhelming. This overestimation is due to the radar’s range, which causes a significant amount of precipitation to evaporate before it reaches the surface. This news is disheartening for nature, which has been longing for rain after enduring the longest period without rainfall in the country’s history. However, there is some hope on the horizon, as next week is expected to bring some relief with predicted rain and thunderstorms. It is important to note, however, that this does not indicate a prolonged period of heavy rainfall. Stay informed about weather updates by subscribing to notifications.
It is truly disheartening to learn that the rain radar system in the Netherlands has been overestimating precipitation. This revelation not only questions the accuracy of the data recorded but also leads to serious implications for water management and resource planning in the country.
Accurate rainfall predictions are crucial for various sectors, including agriculture, water supply, and flood management. If the rain radar system is providing unreliable information, it can lead to misguided decisions and potential disruptions in these essential areas.
The Netherlands, known for its expertise in water management, heavily relies on accurate rainfall data to ensure efficient water usage and prevent flooding. The overestimation of precipitation by the rain radar raises concerns regarding the effectiveness of current flood control measures. False readings could mislead authorities and result in unnecessary responses that could strain resources and affect the lives of citizens.
Additionally, farmers depend on precise rainfall measurements to manage irrigation and determine when and how much to water their crops. Inaccurate readings could adversely impact agricultural practices, impacting food production and ultimately affecting the economy.
It is imperative that the Dutch authorities promptly address this issue by thoroughly investigating the inaccuracies in the rain radar system. Efforts should be focused on rectifying the problem and ensuring that reliable and precise data is provided, enabling the government, citizens, and various sectors to make informed and effective decisions.
In the age of advanced technology, it is disconcerting to witness such discrepancies in essential systems like rain radar. The Netherlands, with its renowned expertise in water management, must take swift action to restore confidence in the accuracy of its rainfall measurements. The nation’s resilience and ability to adapt in the face of climate change depend on it.
