What the site is
Weather Underground is a long-running weather information brand best known for forecasts, radar maps, and hyperlocal conditions. The domain dates back to 1995, which is a meaningful sign of longevity, and the site uses HTTPS with a DigiCert certificate to protect connections. Those are standard but reassuring trust markers for a public information service, especially one that visitors may check daily for planning and safety decisions.
Reputation and verdict
As a recognized weather brand, Weather Underground sits in the mainstream information category rather than a high-risk or obscure niche. The domain is old, operated under a corporate registrar, and appears technically maintained, all of which support legitimacy. Based on the available signals, it looks suitable for general users, with the usual advice to verify any critical forecasts against local official weather alerts when conditions are severe.
