A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 12/30/2025 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 12/31/2025 e 01/06/2026, forecast of predominant precipitation deficit (orange) in the center and east of the monitored region. No positive precipitation anomalies (blue) are forecast for the river basins in the monitored region. Forecast of rainfall close to climatology (white) over the main course of the Amazon River in Peruvian territory, the Aripuanã, Guaporé, Içá, Japurá, Javari, Ji-Paraná, Juruena, Marañon, and Napo river basins.
Forecast for the next 14 days
The figure above shows the prognosis for the 14-day interval between 12/31/2025 e 01/13/2026, forecast of a predominance of precipitation deficit (orange) in the center, east, and southwest of the monitored region. Forecast of positive precipitation anomalies (blue) in the far west of the region, over the main course of the Amazon River in Peruvian territory, and the Içá, Japurá, Marañon, and Napo river basins. Forecast of rainfall close to climatology (white) only over the Javari and Ucayali river basins.
