Short summary
Many decisions require consistent climate information from seasonal to multi-year timescales. We assess seamless forecasts created by constraining seasonal and decadal predictions and compare them with initialised multi-annual forecasts. Multi-annual predictions provide the highest skill, but constrained forecasts still perform well and offer a low-cost, regularly updatable solution for delivering coherent climate information.
