A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 06/16/2026 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 06/17/2026 and 06/23/2026, forecast of a predominance of positive precipitation anomalies (blue) concentrated in the center of the monitored region, over the main course of the Amazon River in Peruvian territory, and the watersheds of the Abacaxis, Aripuanã, Beni, Coari, Guaporé, Iriri, Javari, Ji-Paraná, Juruá, Juruena, Jutaí, Madeira, Mamoré, Purus, Tapajós, Tefé, Teles Pires, and Ucayali rivers, and the main course of the Solimões River. Forecast of precipitation deficit (orange) concentrated in the northern part of the monitored region, along the main course of the Amazon River in Brazilian territory, the Branco and Içá river basins, the left-bank basins of the Amazon River in the northeast and northwest of the state of Pará, and the Napo and Negro river basins. Rainfall close to climatological norms (white) is forecast for the remaining river basins.
Forecast for the next 14 days
The figure shows the prognosis for the 7-day interval between 06/24/2026 and 06/30/2026, forecast of predominantly positive precipitation anomalies (blue) concentrated over the center and northwest of the monitored region. Forecast of precipitation deficit (orange) over the left-bank basins of the Amazon River in the northeast of the state of Pará. Rainfall close to climatological norms (white) is forecast for the main course of the Amazon River within Brazilian territory, the Branco, Curuá Una, and Mamoré river basins, the basins on the left bank of the Amazon River in northeastern Amazonas State and northeastern Pará State, and the Negro and Xingu river basins.
