Climatempo has been Brazil's go-to weather site since 1997, and its trust signals back that history. The company behind it, Climanet Servicos de Internet Ltda, is clearly listed in public records along with real contact names. It ranks in the top 8,000 sites globally, has a clean record with Google safe browsing, and shows up in the Wayback Machine as far back as 1998. Most established weather services have these traits. If you're wondering whether climatempo.com.br is safe to use for weather forecasts and storing your favorite cities, the answer is yes. The one thing to watch for: its SSL certificate expires soon, and there's no obvious contact form on the homepage. But those are minor points for a site that otherwise checks every box. Climatempo.com.br reviews from users are generally positive, and our technical analysis confirms it's a legitimate, well-run service that isn't trying to hide anything.
In plain English
Climatempo.com.br is a legitimate, long-standing weather service for Brazil, backed by a real company with a transparent ownership record. It's been online for nearly three decades and ranks among the most visited sites in its category. The only small gaps are an expiring SSL certificate and a missing contact page, but nothing that undermines trust for a site like this.
Where the score comes from
The site uses HTTPS with a valid certificate, but it's issued by Let's Encrypt and expires in 11 days. There are no browser-level protections like clickjacking prevention, which is a gap for a site that asks users to log in. No malware or phishing flags, so it's not dangerous, just not as polished as it could be.
The domain was registered in 1997 and the WHOIS lists a real Brazilian company (Climanet Servicos de Internet Ltda) with a named responsible person and contact emails. This is as transparent as you'd expect for a legitimate business that's been around for decades.
Climatempo has been online for 27 years, appears in the Wayback Machine since 1998, and ranks among the top 8,000 most visited sites globally. It's not on any blacklists and has a clean bill from Google's safe browsing. This is the footprint of a well-known, trusted brand.
The site has an about page, company disclosure, and links to six social media platforms. However, we didn't find a direct contact page or email on the homepage. For a site with a login feature, that's a minor oversight; most weather services make customer support easy to find.
Privacy policy and terms of service are present, and the site shows a cookie consent notice. For a Brazilian company serving Portuguese-speaking users, these meet the basic legal requirements. Nothing here raises concerns.
The site is behind Cloudflare, uses fast DNS servers, and enforces strict email authentication to prevent spoofing. It's lacking DNSSEC and security headers, but for a weather forecast site, the technical setup is solid and professional.
