A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 10/13/2026 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 10/14/2026 and 10/20/2026, forecast of precipitation deficit (orange) over the main course of the Amazon River in Brazilian territory, the watersheds of the Abacaxis, Branco, Curuá Una, Iriri, and Mamoré rivers, the watersheds 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 watersheds of the Negro and Tapajós rivers. Forecast of positive precipitation anomalies (blue) over the main course of the Amazon River in Peruvian territory, and the watersheds of the Coari, Içá, Ji-Paraná, Jutaí, Madeira, Purus, and Tefé rivers. Precipitation near climatological norms (white) over the remaining monitored watersheds.
Forecast for the next 14 days

The figure shows the prognosis for the 7-day interval between 10/21/2026 and 10/27/2026, forecast of a predominance of precipitation deficits (orange) over nearly the entire monitored region. Precipitation near climatological norms (white) over the Coari River watershed and areas near the headwaters of the Guaporé and Mamoré rivers, as well as the upper and middle Purus.
