Is El Niño behind it?
After a big flood, drought, heatwave or storm, this is the first question people ask. Each page here answers it for one event with one of three lines, and never with an opinion of our own. This site does not attribute weather to El Niño; it reports what official agencies have said.
- Yes, says <agency>
- An official agency has said in its own words that El Niño caused or drove the event. The page quotes the sentence and links to it.
- Partly, says <agency>
- An official agency names El Niño as one factor among others. The page quotes the sentence and links to it.
- No official attribution yet
- No agency has tied the event to El Niño. The page then shows what El Niño usually does in that region — marked as a historical tendency, not an attribution — and what is still unknown.
Agencies counted as official: NOAA and its National Weather Service and Weather Prediction Center, Australia’s Bureau of Meteorology, the World Meteorological Organization and national meteorological services. News reports are not used as a source for an answer. Formal attribution studies take weeks or months, so the third line is common in the first days after an event — it means “not said yet”, not “no”.
