The average rainfall in the driest month is only about 2 mm.
The average maximum temperature of the day each month for
Cirebon (solid red line) is around 34 degrees Celsius. Likewise, the
average minimum temperature (solid blue line) is about 20 degrees
Celsius. The hottest days and coldest nights on average each month
for the past 30 years (dashed red and blue lines) are around 35 and
17 degrees Celsius, respectively. The dominant wind speed in August
is 12 – 19 km/hour for 24,9 days. A study that fulfills the history and
projections of drought in Cirebon shows that, in the future, drought
periods are expected to shift as drought severity increases (Pratiwi
et al., 2018).

2. Cirebon’s Contribution to National Sea Salt Production
Cirebon Regency is one of the largest salt centers in
Indonesia. Cirebon is the second largest salt contributor in West Java
after Indramayu and ranks seventh in Indonesia (Table 2). However,
salt yields in Cirebon have yet to be optimized, considering that the
largest salt fields in Indonesia are Cirebon (3,8 thousand ha) above
Sampang (3 thousand ha), Pati (2,8 thousand ha), and Indramayu
(2,7 thousand ha). The potential of a large land area should be
optimized to support the fulfillment of domestic salt demand.
