This is the official thread for Snow Watch 2018. Feel free to post pictures, information, questions and reports about the snow conditions in the Drakensberg for 2018. The idea is to keep track of the snowfalls, pool information about where the snow is for those that want to go see it, and simply to have a place to express the joy and experiences you may have had if you have witnessed the grandeur of the Dragon clothed in white. This also serves as a historical reference for years to come.

Well, we have had 2 absolutely shocking snow years in a row now. Although the number of falls in 2019/2020 were normal, virtually all of them appeared to be extremely light, most of them only slight dustings. Lets hope things turn around in 2021!

If you base it on science, the chances are about 70% for some good snow this winter. A moister atmosphere as we have had this summer improves those chances but it really depends on moisture supply for a decent dump when the cold season sets in.

One possible mechanism connecting wet summers to cold winters is the La Nina phase of ENSO which we are currently experiencing.
La Nina events are typically associated with wet summers over SA. A characteristic signature of La Nina is also colder than usual sea surface temperatures in the ocean basins surrounding Africa. The image below shows how unusual these temperatures are for the average of the strongest La Nina events since 1970 for the months April, May and June.



La Nina events lead to cool years globally. The oceans take up the heat from the atmosphere.

The image below shows how unusual sea level pressure is for the average of the strongest La Nina events since 1970 for the months April, May and June.



The high pressure system that usually dominates over the interior of SA in winter is shown to be weaker in these previous La Nina years. A strong high pressure system over the interior prevents snowfall events.
