The heart of the Bay Area. Ancient redwoods tower above. Salmon swim in meandering creeks. A history lesson in gold and shrimp on the edge of San Pablo Bay. The Bay Area is stunning during spring.
Hillsides turn green, flowers bloom and migrating species return.
Seasonal changes in the earth's position relative to the sun causes the shift from winter to spring. Spring wind, the characteristic weather condition, is responsible for the weather, the food chain and, to some degree, the landscape. The source for the seasonal change begins as the earth, tilted on its axis toward the sun, heats the earth's surface in our region. A high-pressure air mass, the North Pacific High, forms as warm air rises offshore. As it strengthens, it buffers the Bay Area from storm systems.
