WMO head of regional climate prediction services Wilfran Moufouma Okia said temperatures were expected to be above average in a wide band of the world including the Caribbean, central America and the northern part of South America.
"The tropical Pacific Ocean is currently experiencing El Niño conditions, and this is a result of rapid and substantive change both in the atmosphere and in the ocean," he said.
But it left the ENSO Outlook at El Nino Alert, rather than following its American counterparts in an upgrade.
Former NSW Fire and Rescue Commissioner Greg Mullins warned parts of Australia untouched by the Black Summer bushfires are at risk because of this.
"We are in uncharted territory with El Niño," Mullins said during the Climate Council's El Niño media briefing.
"Decades ago, you couldn't have a bad fire season without the intensifying effects of El Niño.
"Since the Black Saturday fires of 2009 in Victoria that killed 173 people, you haven't needed El Niño to have a bad fire season because things have warmed so intensely and cool season rainfall has reduced by 10 to 20 per cent and that is accumulative.
"We're set for a bad year."
An El Nino is a natural, temporary and occasional warming of part of the Pacific that shifts weather patterns across the globe, often by moving the airborne paths for storms.
The world earlier this year got out of an unusually long-lasting and strong La Nina — El Nino's flip side with cooling — that exacerbated regular flooding across Australia.

El Nino strongly tilts Australia toward drier and warmer conditions with northern South America — Brazil, Colombia and Venezuela — likely to be drier and south-east Argentina and parts of Chile likely to be wetter, she said.
India and Indonesia also tend to be dry through August in El Ninos.
While traditionally it means fewer hurricanes in the Atlantic, it often means more tropical cyclones in the Pacific.
In the past, a strong El Nino has led to record global warmth, like in 2016 and 1998.
