Climate

According to the Köppen climate classification system, Long Beach and the Long Beach Peninsula have a moist (in winter), cool warm-summer mediterranean climate (Csb), with cool, but long, dry summers and mild winters. Both extreme heat and extreme cold are rare. The record high temperature is 99 °F (37 °C) on August 10, 1981, and June 27, 2021, and the record low is 0 °F (−18 °C) on December 8, 1972. Long Beach records nearly 80 inches (2,000 mm) of rainfall annually. Snow is far less common than rain, but can happen every once in a while.

Earthquake and tsunami vulnerability

If a magnitude 9.0 earthquake were to hit the Cascadia subduction zone, emergency planners estimate the first tsunami waves could hit Long Beach 20 to 25 minutes later.

At a December 2016 open house, the city government presented initial plans for a proposed 32-foot (9.8 m) berm which could potentially accommodate 850 persons. The structure would have had a "modified prow," much like a ship looking out to sea.^[16] The shape was also designed to withstand the backwash from a tsunami. The total cost was estimated at $3.4 million, of which the Federal Emergency Management Agency (FEMA) was to pay 75%, the Emergency Management Division of Washington State 12.5%, and the City of Long Beach 12.5%.^[17] The project was abandoned in 2017 after new scientific reports indicated it was designed at least 14.5 feet (4.4 m) too short to withstand a worst-case tsunami.^[18][19]
