Climate Zone 4A, Mixed/Humid – Mixed, humid climates experience all four seasons, but season length
and extremity vary by location. These regions receive more than 20 inches of rain annually. The average
winter temperature typically drops below 45°F. Summers can be extremely hot and humid. Many of these
regions will experience some snowfall and icing during winter months.

Climate Zone 4C, Mixed/Marine – Temperate climates found on the coast. These areas typically do not
have extreme seasons. Temperatures remain relatively mild year-round due to the high heat capacity of
water. Marine climates only experience two seasons, summer and winter. Summer months are dry, while
winter can be very wet. To be considered a marine climate, 65% of annual total rainfall must occur in less
than six months of the year. These climates are generally humid, but moisture and precipitation levels
can vary greatly by location.
