I have been many years in coffee and have seen pretty much all of the weather forecasters. Almost all of them did not predict the frost of 1994 and this latest one. They use old methods and just regurgitate the GFS and Euro models.
The one exception has been Hackett Financial Advisors. They called this frost in Brazil in the face of strong criticism. They stuck to their guns and they were dead right.
I don't work for them or have any interest in the company. Just giving credit where it is do. If you really want to know what is ahead of us in the weather contact them.
