KNMI

What is KNMI?

KNMI is a weather app that helps people check forecasts, follow rain and temperature conditions, and receive official severe weather warnings for the Netherlands. It is published by KNMI, the Dutch national meteorological institute, and is designed for users who want local weather information from an official public source. The app provides hourly and daily forecasts, precipitation radar, warning levels such as red, orange, and yellow, and guidance about what to expect during hazardous weather. It also includes supporting information such as sunrise and sunset times, heat-related outlooks, UV information, and measurement maps that combine KNMI station data with citizen observations. For people in the Netherlands, it is a practical tool for daily planning, travel decisions, and staying informed during storms, heavy rain, heat, or other disruptive conditions.

Safety overview

Status: Safe

This is an official weather app from a national meteorological institute. Access to location and notifications is normal for weather forecasts and alerts, and those permissions can be limited in macOS or iOS settings if you prefer. If you remove the app, you will lose saved locations, weather alerts, and quick access to its forecasts unless that information is synced elsewhere.

Recommendation: Keep KNMI if you rely on Dutch weather forecasts or official warning notifications. If you no longer use it, removing it is generally fine and only affects the app’s alerts, saved places, and convenience features.
