Simcoe is located outside the principal snow belt areas of Southern Ontario and in close proximity to the moderating effects of Lake Erie, keeping it comparably warmer in the winter months and cooler in the summer months than surrounding lands. This comfortable climate supports native plants usually found in more southerly areas such as Georgia and the Carolinas. Examples of such plants located in this area are the Sycamore, Cucumber Tree, and the Tulip Tree.

Since Simcoe is not surrounded by large urbanized areas, climatic elements caused by urbanization are not evident. Compared to urbanized areas, Simcoe generally experiences 5% - 10% less precipitation and 5 – 25 times less gaseous air pollutants, while sunshine duration is between 5% - 15% more. All these factors make living and working in Simcoe a healthy and enjoyable experience.
