Seasonal forecasts look very different from traditional short-range forecasts. These are the two main differences:

  • seasonal forecasts cover the meteorological elements mean values for 3 months;
  • seasonal forecasts are in terms of probability.

NIMH issues a synthesis of the seasonal forecasts from several leading world centres.

Winter (December-January-February): With mean seasonal temperature and seasonal rainfall/snowfall near normal. Winter 2016/17 should be colder and less wet than winter 2015/16.

Spring (March-April-May): With mean seasonal temperature near or above normal and seasonal rainfall near normal. Spring 2017 should be similar to spring 2016 or less warm and with less precipitation.

The seasonal forecast is updated in the interval 27-th-30-th every month.
