The forecast through February 2026 expects deficits in Central and Eastern Europe, Central Asia, and the Levant. Surpluses are expected in the western Amazon, the Sahel and southern Africa, and northeastern Australia.
Severe to exceptional surpluses will remain throughout Queensland. Exceptional deficits will occur in portions of Victoria, Western Australia, Tasmania, and New Zealand.
Exceptional deficits will occur in northwestern and southeastern China, widespread throughout the Yangtze River Basin. Isolated pockets of surplus will affect portions of central and northeastern China.
Exceptional surpluses throughout Maritime Southeast Asia will mostly diminish, though pockets of severe to exceptional deficits will persist in portions of the Philippines, Indonesia, Papua, West Papua, and New Guinea.
The forecast through July indicates that intense water deficits observed in Mexico will downgrade considerably. Severe to extreme deficits are, however, expected in Baja and along the Pacific Coast from Sinaloa through Guerrero. Severe deficits are forecast for Tabasco and moderate deficits elsewhere around the Gulf of Mexico. Moderate deficits are also expected in Guatemala, El Salvador, Haiti, and western Cuba.
The forecast through July indicates widespread water deficits throughout much of Europe, including exceptional deficits in Finland, Estonia, Latvia, Lithuania, and Belarus. Moderate to extreme deficits are forecast for remaining areas of Europe and will be especially intense in southern Germany and along many rivers including the Danube, Drava, Allier, and Dordogne. Moderate surpluses are forecast for Ireland, and intense surpluses for southeastern Spain.
The forecast through July indicates that widespread water surpluses will nearly disappear in southeastern China but will persist in the south and will include exceptional anomalies. Taiwan will transition from deficit to moderate surplus. Exceptional deficits will persist in western Inner Mongolia, and moderate to extreme deficits in Mongolia. Deficits are forecast between the Yellow and Yangtze Rivers. Severe deficits are forecast for northern Japan.
The forecast through July indicates that widespread, exceptional water deficits will shrink considerably. Severe to exceptional deficits are, however, forecast in northern Australia from the Kimberly region through Top End, Northern Territory and along the southern shore of the Gulf of Carpentaria. Deficits will also be intense in the southern tip of Western Australia, Tasmania, New Caledonia, and North Island, New Zealand.
ISciences is transitioning production of our monthly Global Water Monitor & Forecast Watch List reports to use outputs from a new version of our Water Security Indicator Model (WSIM). WSIMv2 makes use of more recent and publicly available input datasets and uses a revised methodology for calculating composite water anomalies.
