It is difficult to name March a spring month, for snow cover remains on the ground well into the end of the month. Everything remains winter-like. However, rains are a sure sign of upcoming spring. March is the wettest month of the year in Boston with 13 rainy days.
April marks the true beginning of spring. Temperatures rise, snow melts, and flowers start blooming. It is also the start of cruising and boating season. Flower season continues into mid-May. The temperatures are growing higher and rains return, this time with thunderstorms.
