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.

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

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