Waltham is inland but still close to the Atlantic Ocean. The ocean can soften some temperature changes, while the town’s distance from the coast allows colder winter nights and warmer summer days. The Charles River, nearby hills, and paved areas also affect local temperatures and winds. City areas may stay warmer at night than nearby wooded places.
Rain and snow can occur in every season, but summer storms are often short and heavy. Fall is usually cool and colorful, while spring can change quickly from chilly to warm. Overall, Waltham has a humid continental climate with warm summers, cold winters, and precipitation spread through the year.
