Dongguan lychees have a longstanding reputation and right now is the season when lychees bear fruit. But because of the weather, the lychees haven't blossomed as much as usual and the fruits are reduced too as a result. A reduced lychee production is therefore a safe prediction.
In fact, lychees have rather strict requirements towards temperature conditions. If the temperature is too high, the lychees don't blossom. The fact that the lychees didn't blossom in great numbers is due to the long stretch of high temperature in the year before. Only when the temperature is moderate and a satisfying amount of rainfall is maintained, can the lychees absorb enough water to blossom. In a month's time, the large lychees will be ready to go on sale. But because the production volume has decreased, the price of the large lychees have a high chance of doubling in price. So anyone who wants to enjoy the superb taste of lychees this year, will have to consider paying the price.
