radar.weather.gov is the official National Weather Service radar viewer, and the .gov domain alone is a strong trust signal. Only verified U.S. government agencies can register .gov addresses, so this site is exactly what it appears to be. It has been archived on the Wayback Machine for over 23 years, with no history of malware or abuse. The site uses HTTPS and loads quickly on Akamai's network. Some automated checks flagged hidden content, but that's because the site is a single-page app that loads map data dynamically, not a sign of deception. If you're looking for real-time weather radar from the NWS, this is the authoritative source. There are no commercial ads or data collection concerns typical of private weather sites.

How we score →
Where the score comes from
We look at six areas. Here's how radar.weather.gov did in each.
75
Security
The site uses HTTPS with a valid certificate and enforces it via HSTS, which is good. But it's missing some modern browser protections like content security policies, which most government sites now implement.
95
Identity
The .gov domain is a restricted, highly trusted TLD that only official U.S. government entities can use. The site has been around for over 23 years, which is a strong indicator of legitimacy.
95
Reputation
No blacklists, no malware flags, and a clean 23-year history in the Wayback Machine. This is a well-established site with no negative reputation signals.
85
Transparency
The site is a single-page app, so some contact info wasn't visible to our automated checks. But the .gov domain and clear NWS branding make the owner obvious. A legal info page exists, which is typical for a government service.
90
Compliance
Government sites are held to high legal standards. The presence of a 'Legal Information' heading suggests privacy and terms exist, even if our scanner couldn't render them. No compliance red flags.
85
Infrastructure
Hosted on Akamai, a top-tier content delivery network, with fast load times and modern TLS. The hidden content warning is likely due to the JavaScript-heavy design, not deception.
