Have you tried this app? Seems pretty accurate to me and it's free. My buddy lives a little north of Canadensis just over the Pike County line. He's at 1836 feet. Amazing difference in weather at that elevation. He's often in the clouds when the deck is low and always a good 4-6 degrees cooler than at the bottom of the hill.
We've had some intense storms here in Ocean county recently. In some places the soil is almost pure sand so it drains and dries quickly. Despite the rains, I still have drip irrigation on in the garden because of this.
