A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 04/14/2026 for the next 7 and 14 days.
The calibrated sub-seasonal multi-model forecast CPTEC/INPE-FUNCEME is generated through scientific cooperation between CPTEC/INPE and FUNCEME, and comes from a set of 4 global models (a Brazilian model, BAM-1.2/CPTEC, and three US models, CFSv2/NCEP, GEFSv12/NCEP and ESRL/NOAA, the latter three from the SubX project). Brazilian model, BAM-1.2/CPTEC, and three US models, CFSv2/NCEP, GEFSv12/NCEP, and ESRL/NOAA, the latter three from the SubX project). The forecast precipitation anomalies are determined in relation to the climatological period from 1999 to 2016. The outputs for the 7 and 14-day forecast intervals are shown below, detailing the forecast behavior of the basins of interest.
Forecast for the next 7 days
The figure above shows the forecast for the 7-day interval between 04/15/2026 and 04/21/2026, forecast of predominantly positive precipitation anomalies (blue) over almost the entire monitored region. No precipitation deficit (orange) is forecast to predominate over the monitored region. Rainfall close to climatological norms (white) is forecast over the main course of the Amazon River in Peruvian territory, and the basins of the Curuá Una, Içá, and Xingu rivers.
Forecast for the next 14 days
The figure above shows the prognosis for the 7-day interval between 04/22/2026 and 04/28/2026, forecast of a predominance of positive precipitation anomalies (blue) over the main course of the Amazon River in Brazilian and Peruvian territories, the basins of the Abacaxis, Branco, Coari, Curuá Una, Iriri, Javari, Juruá, Jutaí, Madeira, and Marañon river basins; the left-bank basins of the Amazon River in northeastern Amazonas State and in the northeast and northwest of Pará State; and the Napo, Purus, Tapajós, and Tefé river basins. Forecast of a predominance of precipitation deficits (orange) over the Mamoré River basin. Forecast of rainfall close to climatological norms (white) over the other monitored basins.
