The word "fine" has already been phased out in Victoria where a preliminary trial of a new seven-day forecasting service in a whopping 80 centres has been overwhelmingly successful.

The new system is using fully-worded descriptions to detail conditions more accurately for the week ahead.

Depending on the final outcome of the project the new system could be rolled out nationally, doing away with the often frustrating description "fine" to avoid confusion with its other meanings like "excellent", "comfortable" or "high quality".

The Bureau's national manager of public, marine and agricultural weather services, Alasdair Hainsworth, said the new system has the capacity to provide more information about a particular week's weather conditions than just words like "fine".

He said farmers would probably agree extended periods of hot, dry weather were anything but fine or excellent, and therefore improved forecasts with detailed descriptions using temperatures, sky conditions, wind and rain outlooks would better inform them and others reliant on the weather.

"A word like 'fine' can mean different things to different people," Mr Hainsworth said.

"From market research we've done, 'fine' in particular is not a word that is well understood in the community.

"Surfers who hear the word 'fine' can think it's a good day to go surfing, and that is simply not the case.

"Many people interpret 'fine' as a nice day, which is sunny, with light winds, when our definition in the Bureau is no rain.

"It could still be very windy, hot or cloudy and be a 'fine' day, which is why we're trying to eliminate it from the forecast."

Mr Hainsworth said the new generation system is the biggest revamp to forecasting at the bureau in 20 years.

He said the Victorian trial commenced in October and would run at least six months before a decision was made on any national roll-out.

An online survey on the new system had so far recorded strong support among about 88pc of responses.
