A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 10/6/2026 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 shows the forecast for the 7-day interval between 10/07/2026 and 10/13/2026, forecast of precipitation deficits (orange) over much of the monitored region, concentrated in the central and eastern parts of the monitored region. Precipitation near climatological norms (white) concentrated in the western part of the monitored region, over the main course of the Amazon River in Peruvian territory, and in the watersheds of the Içá, Japurá, Javari, Marañon, Napo, and Ucayali rivers.
Forecast for the next 14 days

The figure shows the prognosis for the 7-day interval between 10/14/2026 and 10/20/2026, forecast of a predominance of precipitation deficit (orange) over the main course of the Amazon River in Brazilian territory, the watersheds of the Abacaxis, Beni, Branco, Curuá Una, Javari, and Juruá rivers; the left-bank basins of the Amazon River in the northeast of the state of Amazonas; the northeast and northwest of the state of Pará; and the Negro, Tapajós, and Ucayali river basins. Positive precipitation anomalies (blue) are forecast to be concentrated in the southeastern part of the monitored region, over the Guaporé, Juruena, Teles Pires, and Xingu river basins. Precipitation near climatological norms (white) is forecast for the remaining river basins.
