A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 06/23/2026 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 06/24/2026 and 06/30/2026, forecast of predominantly positive precipitation anomalies (blue) concentrated in the central and western parts of the monitored area, over the main course of the Amazon River in Brazilian and Peruvian territory, and the watersheds of the Abacaxis, Branco, Coari, Içá, Japurá, Javari, Juruá, and Jutaí rivers, Madeira, and Marañon 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; the basins of the Napo, Negro, Purus, Tapajós, Tefé, and Ucayali rivers; and the main course of the Solimões River. Precipitation deficit forecast (orange) only for the Beni and Mamoré river basins. Rainfall close to normal (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 07/01/2026 and 07/07/2026, forecast of rainfall levels close to climatological norms in most of the monitored river basins; forecast of positive precipitation anomalies (blue) in the north and northwest of the monitored area over the river basins of the Branco, Coari, Japurá, Napo, Negro, and Tefé rivers; the basins on the left bank of the Amazon River in the northeast of the state of Amazonas; and the main course of the Solimões River. Precipitation deficits (orange) are forecast only over the Beni and Mamoré river basins in the southwest of the region.
