I want to know the answer to the following question:
On average, how much lower are the temperatures in the central areas in celsius?
All the background I'm provided with is that "Jamestown also has a very low annual rainfall, while 750–1,000 mm (30–39 in) falls per year on the higher ground and the south coast, where it is also noticeably cloudier.". Is that enough to answer the question?
Answer: no
