Yantai City is located at the northern tip of the Shandong Peninsula, bordering the Bohai Sea to the north and the Yellow Sea to the east. Its climate is influenced by both continental monsoon and maritime climates, primarily belonging to the warm temperate continental monsoon climate zone. However, the moderating effect of the ocean is significant, resulting in a complex climate characterized by mild winters, cool summers, and distinct seasons with clear transitions. The specific characteristics are as follows:
Seasonal Characteristics
Spring (March-May): Fluctuating temperatures, windy with little rain, relatively dry air, and frequent "late spring cold snaps."
Summer (June-August): High temperatures and abundant rainfall, accounting for 60%-70% of annual precipitation. Occasionally affected by typhoons, but only 3-5 days with extreme high temperatures (≥35℃).
Autumn (September-November): Clear skies, large diurnal temperature range, and excellent air quality, suitable for crop growth.
Winter (December-February): Cold and dry, with an average temperature of -1.2℃ in the coldest month, and extreme lows rarely falling below -10℃. Coastal areas are milder.
Temperature and Precipitation
Temperature: Annual average temperature 12-13℃, average summer temperature 25℃, average winter temperature -1.5℃, with smaller temperature differences along the coast.
Precipitation: Annual precipitation 500-700 mm, 60% concentrated in summer, with spring prone to drought.
Humidity and Sunshine: Annual average relative humidity 68%, humid but not damp; annual sunshine 2500-2600 hours, with the most in May.
Marine Moderating Effect: The ocean makes Yantai 3-5℃ warmer in winter than inland areas at the same latitude, and cooler in summer. The annual temperature difference is about 26℃, and the frost-free period is 236-282 days, suitable for growing crops such as apples and cherries.
