Happy New Year 2022!

At the start of 2022, let’s look back at the complex history of humans and learn its best lessons to make our society better.
Lychees – their cultivation has dated back all the way to the 11th century. This simple fruit encorporates the long history of humans and has been pictured in Chinese literature from the earliest known record in 1059 A.D. In the18th century it was carried to India and from there reached Reunion Island, where Reuniwatt’s team can savour fresh lychees today. Wherever it arrived, it quickly enjoyed great prestige. In Reunion Island, lychees are said to bring joy and happiness and are traditionally eaten around the New Year.

In the past decade, Reuniwatt has mastered the art of cloud observation and cloud forecasting. We’ve built long-lasting relationships with you, our supporters and customers. Good, reliable connections reach around the globe, just as the sweet lychee conquered the world. We are eagerly looking forward to meeting you again. In 2022, we will continue to deliver the best-in-class service to you and wish you that you can enjoy every day of 2022 like a succulent lychee experience!
