Many sight-impaired readers use lynx and other text-based browsers and a speech-to-text engine like festival to read these pages.
In a statement sent in response to a query from iTWire, the BoM said: "The Bureau has now resolved an issue that inadvertently caused problems with the Lynx web-browser. The issue was caused with use of a tool that detects and stops screen scraping activity on the Bureau's website.
The BoM site viewed with lynx on Tuesday morning.
"The tool was not intended to disrupt users to the website, only traffic that is identified as automated screen scraping. The Bureau has strengthened its stance on screen scraping activities, which can invite malicious activity and weaken security protection, in addition to consuming bandwidth."
"The accessibility of Bureau services to all members of the community is of great importance," the spokesperson added.

"The Bureau makes data and materials available to third parties through our Registered Users channels, and we are endeavouring to transition those who are screen scraping to becoming Registered Users."
