Investigation Brief
The site offers a free service that adds daily weather forecasts as events to Google Calendar. No malicious behavior, credential harvesting, or deceptive monetization is observed. The hosting IP carries moderate abuse reports, but the page itself shows no harmful activity.
What the site appears to do
WeatherCalendar.io presents itself as a free Google Calendar add-on that automatically inserts daily weather forecasts as calendar events. The page shows a prominent blue button labeled "Add Weather to Calendar — Free" and states the service works with Google Calendar. No login forms, payment requests, or download prompts appear on the captured page.
Strongest evidence and limitations
major browser blocklists and the antivirus scan both returned clean results with zero malicious detections. TLS is valid and properly configured. The hosting IP (185.158.133.1) has an abuse confidence score of 61/100 across 38 reports, indicating the IP has been associated with other suspicious activity in the past. No direct contact email or operator identity is visible on the page, and no external research produced independent complaints or warnings about this specific domain.
Practical user impact
Users who click the button are redirected to Google’s OAuth consent screen to grant calendar access. The service claims to be free and private, but the lack of published contact information and the IP’s abuse history introduce moderate operator risk. No evidence of data theft, hidden charges, or forced redirects was found on the scanned page.
Why the score is 82
The hosting IP has an abuse confidence score of 61/100 across 38 saved reports. Coverage remains separate so missing sources cannot be mistaken for clean results.

Web research findings
Independent findings for weathercalendar.io, including public complaints, named review sources, registration records, and look-alike-domain evidence. A missing result is shown as unverified, never converted into a clean bill of health.

Domain & infrastructure
The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.
