Microclimate

So this photograph was taken the day before the single leaf photo. I was grinding my way up this mile-long hill the next town over, on my bike ride, and suddenly was dazzled by this blast of color in the light of the setting sun. I couldn't believe that with hardly a leaf on my street, these trees seemed fully leafed out. I am guessing it is a "microclimate." According to Wikipedia: "A microclimate is a local atmospheric zone where the climate differs from the surrounding area. The term may refer to areas as small as a few square feet (for example a garden bed) or as large as many square miles." So I am guessing that's why this street has leaves, and mine doesn't.
