Rainfall significantly decreases compared to winter, with April and May being notably drier, though an occasional spring shower is not uncommon.

While some might find it a bit melancholic, this marine layer keeps temperatures cool and comfortable, providing a natural air conditioning effect and preventing intense heat. Ocean temperatures slowly begin to rise, reaching the mid- to upper-50s (12-14°C) by May, making it more inviting for those in wetsuits. This is a fantastic time for outdoor activities such as hiking the local trails, cycling along the coast, or enjoying a round of golf.

Crowds are still manageable compared to the peak summer months, making it easier to secure reservations at popular restaurants or find parking near the beaches. Spring is also an excellent season for exploring Balboa Island, taking a ferry ride, or simply relaxing by the harbor. The air quality tends to be excellent, and the blend of cool mornings and warm afternoons provides a perfect environment for almost any activity. For those planning a visit, packing layers is still key, as the temperature can vary significantly between the foggy mornings and sunny afternoons. Newport Beach in spring offers a taste of the coming summer warmth without the intensity, making it a charming and inviting period for both active adventurers and those seeking relaxed coastal enjoyment, truly showcasing the best of Southern California’s pleasant climate before the summer rush.

Summer Sunshine: June, July, and August in Newport Beach

The weather in Newport Beach, CA by month during the summer — June, July, and August — signifies the peak of tourist season, drawing visitors with promises of abundant sunshine and quintessential Southern California beach days. While these are the warmest months, Newport Beach’s coastal location ensures a moderate climate, rarely reaching extreme heat. Average high temperatures consistently hover in the mid-70s Fahrenheit (23-24°C), occasionally touching the low 80s (27°C) during heat waves that are usually short-lived. Overnight lows are very comfortable, typically in the mid-60s (18-19°C), perfect for evening strolls and al fresco dining. A notable characteristic of early summer is the continuation of “June Gloom,” where a persistent marine layer brings cloudy or foggy mornings, often burning off to reveal glorious sunshine by midday or early afternoon.

Rainfall is virtually non-existent during these months, guaranteeing dry, sunny conditions for outdoor activities. Ocean temperatures are at their warmest, ranging from the upper 60s to low 70s Fahrenheit (19-22°C), making swimming, surfing, paddleboarding, and other water sports incredibly inviting.

This is the prime time for enjoying all that Newport Beach has to offer, from expansive stretches of sand to the vibrant Balboa Peninsula. Consider visiting the Balboa Fun Zone, taking a whale watching tour, or exploring the tide pools during low tide. Despite the crowds, the vastness of the beaches and the numerous recreational opportunities ensure there’s always space to enjoy. Early mornings before the marine layer burns off can be surprisingly cool and peaceful, perfect for a quiet walk or jog along the boardwalk before the day truly heats up.

Always remember to bring sunscreen, hats, and sunglasses, as UV index can be high even on cloudy days, and hydration is crucial for extended outdoor activities under the summer sun.

Autumn’s Embrace: September, October, and November in Newport Beach

Many locals and savvy visitors consider autumn to offer the absolute best weather in Newport Beach, CA by month, often referring to September, October, and even early November as the “second summer”. This period is characterized by consistently warm temperatures, clear skies, and a noticeable decrease in crowds compared to the bustling summer months, creating an idyllic and serene atmosphere.

The most significant advantage of autumn is the ocean temperature, which remains at its warmest through September and into October, often hovering in the upper 60s (19-21°C) or even low 70s (21-22°C). This makes swimming, surfing, and paddleboarding particularly enjoyable, as the water is still very inviting. Rainfall is minimal in September and October, with clear, sunny days being the norm.
