Wimmera fire agencies, in conjunction with the Department of Education, decided to close the school and kinder on Monday morning.

Incident controller Jon Rofe said there while the Grampians fire was still active and burning within containment lines, high temperatures and winds predicted for Monday put the school in a high risk area if an incident was to occur.

"February is traditionally the worst month for fires, with hot weather and dryness expected to continue for some time. The fire risk will remain until significant rain is received," he said.

Mr Rofe said containing the Grampians fire had been a mammoth task.

"It has been an arduous few weeks for the crews and incident management team working around the clock. The fire has burned more than 55,100 hectares," he said. 

"Throughout the past few weeks, other agencies such as Victorian Police, SES, Department of Human Services, Ambulance Victoria, councils, utility companies and others have worked in partnership with fire agencies to protect communities in the Grampians area.

"The hard work isn't over yet and we need to prepare for the continued hot weather expected later in the week and also for what else the rest of the fire season might have in store."

The Bureau of Meteorology has predicted a strong southerly wind change for Monday which could be accompanied by lightning.

Fire Services Commissioner Craig Lapsley said the wind change could pose a significant risk for fires that were being managed and any new fires that started.
