A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 04/21/2026 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 above shows the forecast for the 7-day interval between 04/22/2026 and 04/28/2026, forecast of a predominance of precipitation deficits (orange) along the main course of the Amazon River in Brazilian and Peruvian territories, the Juruena River basin, the basins on the left bank of the Amazon River in the northeast and northwest of the state of Pará, and the Napo, Teles Pires, and Ucayali basins. Forecast of predominantly positive precipitation anomalies (blue) over the Beni, Branco, Juruá, Marañon, and Ucayali river basins. Precipitation near climatological norms (white) is forecast for the remaining monitored basins.

Forecast for the next 14 days

multimodel_calibrado

The figure above shows the prognosis for the 7-day interval between 04/29/2026 and 05/05/2026, forecast of a predominance of precipitation deficits (orange) over the main course of the Amazon River in Peruvian territory, the Branco, Curuá Una, Guaporé Içá, Iriri, and Mamoré river basins, the basins on the left bank of the Amazon River in the northeast and northwest of the state of Pará, and the Napo, Negro, Teles Pires, and Xingu basins. No positive precipitation anomalies (blue) are forecast for the monitored region. Precipitation close to climatological norms (white) is forecast for the other monitored basins.
