Rainfall data back to 1910 is only available for Telegraph Point: data for Port Macquarie goes back only to 1996. The graph includes both but they are very similar in pattern but Port Macquarie receives a little ore rain than telegraph Point. In the 1910s and 1940s the 9 year average fell to 1000mms while it has been up around 1300 to 1500mms since the 1950's. This pattern does now show the slight decline found often in South East Australia.
