Pacific Grove weather by month
Pacific Grove, California, affectionately known as “Butterfly Town USA,” is a charming coastal community nestled on the Monterey Peninsula. Its unique location offers a surprisingly diverse climate, influenced by the Pacific Ocean and the surrounding hills. Planning a visit? Understanding the weather patterns throughout the year is key to making the most of your trip. This guide breaks down the Pacific Grove weather by month, helping you pack appropriately and anticipate what to expect.
Overview of Pacific Grove’s Climate
Pacific Grove enjoys a Mediterranean climate, characterized by mild, wet winters and cool, dry summers. However, it’s significantly cooler and foggier than many other parts of California due to its proximity to Monterey Bay and the frequent upwelling of cold ocean water. This creates a microclimate that’s often shrouded in mist, especially during the summer months – a phenomenon locals affectionately call “June Gloom.” Expect average temperatures to range from the 50s to the 60s throughout the year, with occasional dips and spikes.

Spring (March – May): Blooming Beauty
Spring is a fantastic time to visit Pacific Grove. The weather warms up, wildflowers burst into color, and the fog begins to dissipate. March and April can still be a bit unpredictable, with occasional showers, but May typically offers sunny skies and comfortable temperatures. This is an excellent time for hiking, exploring Point Lobos State Natural Reserve, and enjoying the outdoors.
Summer (June – August): Cool Coastal Breezes
Despite being summer, Pacific Grove doesn’t experience the scorching heat of inland California. The “June Gloom” phenomenon is common, meaning mornings are often shrouded in fog that burns off (sometimes) by the afternoon. July and August are the warmest months, but temperatures rarely exceed 70°F. Pack layers, as the evenings can be cool. This is peak season for tourism, so expect larger crowds.
Autumn (September – November): Golden Hues & Whale Watching
Autumn brings warm ocean temperatures and often the clearest skies of the year. September is particularly pleasant, with warm days and cool evenings. As the months progress, the fog returns, and rainfall increases. This is the start of whale watching season, as gray whales begin their migration south.
Winter (December – February): Cozy & Stormy
Winter in Pacific Grove is mild compared to many other parts of the country, but it’s the wettest and coolest time of year. Expect frequent rain showers and occasional storms. While not ideal for sunbathing, winter offers a cozy atmosphere, perfect for enjoying the town’s charming shops and restaurants. It’s also a prime time for storm watching along the coast.
