April shows the first signs of warmth in the spring of Michigan and brings greenery to the landscape. The average high temperatures are in the warm zone of 46°F (7.8°C) to 60°F (15.6°C), and the average low temperatures are between a cold 25°F (-3.9°C) to 38°F (3.3°C). Detroit in the southeast averages between 39°F (3.9°C) to 59°F (15°C), while Benton Harbor in the west is between 38°F (3.3°C) to 68°F (20°C). The rainfall ranges from 2" (51mm) in the south to 8" (203mm) in the Upper Peninsula, as fresh snow keeps the roads slippery. The sunshine improves significantly, but the sun is yet to reach its peak intensity. The regions near the Great Lakes are slightly warmer than the rest of the state. Spring is an ideal time for boating, kayaking, biking, and hiking with thousands of lakes in the state. Michigan rivers are shallow and calm to enjoy rafting in the mild weather. The waterfalls roar gracefully with the melting of snow and heavy rainfall in spring in April in Michigan.
