The rainfall map shows the average annual rainfall for your area, which is nice to know -- if you don't want to have to do a lot of watering, then choose plants whose water requirements match your area's annual rainfall amounts.
On the other hand, some plants from very dry areas can't tolerate a lot of water. For example, you wouldn't want to plant desert plants in a swampy area or a rainforest climate, because they would probably rot.
So knowing your average rainfall totals can help save you time and money when choosing a plant for your area.

Climate change has led to variations in the rainfall patterns, so these maps should be used as guidelines more than anything else. If you need exact data on rainfall patterns, your best choice is to contact your local agricultural office or county extension, as they keep up to date and detailed information from year to year.
