A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 07/28/2026 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

multimodel_calibrado_seven_days

The figure shows the forecast for the 7-day interval between 07/29/2026 and 08/04/2026, forecast of predominantly positive precipitation anomalies (blue) in the west and southwest of the monitored region, over the main course of the Amazon River in Peruvian territory, the watersheds of the Aripuanã, Beni, Guaporé, Içá, Japurá, Javari, Juruá, Jutaí, Madeira, Napo, Purus, Tefé, and Ucayali rivers. Forecast of precipitation deficits (orange) concentrated in the north and northeast of the monitored area, along the main course of the Amazon River in Brazilian territory, the Branco and Curuá Una river basins, the basins on the left bank of the Amazon River in the northeast of the state of Amazonas, the northeast and northwest of the state of Pará, and the Negro River basin. Rainfall close to climatological norms (white) is forecast for the remaining river basins.

Forecast for the next 14 days

multimodel_calibrado

The figure shows the prognosis for the 7-day interval between 08/05/2026 and 08/11/2026, forecast of positive precipitation anomalies (blue) in areas in the central and western parts of the monitored region, along the main course of the Amazon River in Peruvian territory, and in the watersheds of the Aripuanã, Içá, Javari, Ji-Paraná, Juruá, Juruena, Madeira, Napo, and Ucayali rivers. Forecast of precipitation deficits (orange) concentrated in the north and northeast of the monitored area, along the main course of the Amazon River in Brazilian territory, the Branco and Curuá Una river basins, and the basins on the left bank of the Amazon River in the northeast of the state of Amazonas and the northeast and northwest of the state of Pará. Rainfall close to climatological norms (white) is forecast for the remaining river basins.
