Overview
- Forecasters say this week will be mild and largely dry with daytime highs around 20–24°C and a warming trend toward about 24–25°C by Friday and Saturday.
- A north to northwest flow will produce cool nights of roughly 10–15°C and fresher air that keeps daytime temperatures below typical Hondsdagen values.
- Light cloud and a few localized showers are possible midweek but the chance of heavier showers or downpours rises from Sunday as the weekend warms.
- Recent small rainfalls do not end the national water shortage, so authorities are keeping drought measures such as adjusted river controls in place to limit salt intrusion and manage flows.
- Radboudumc researchers have begun fitting twenty Nijmeegse Vierdaagse participants with mobile weather stations to map temperature and humidity along routes so organizers can identify hot spots and place water points where needed.
