These months see a slight increase in rainfall, with March often being the month with the highest number of rainy days, although the total amount of precipitation still remains low.

The summer period, especially from June to September, in Santa Monica is characterized by warm and sunny weather. During the day, air temperatures in July and August often rise above 30°C, creating ideal conditions for relaxing by the ocean.

However, nights become noticeably cooler: minimum temperatures can drop to 6.7°C in February. Such daily temperature fluctuations are also characteristic of the winter period, so it's worth bringing warmer clothes for evening outings.

Santa Monica experiences a distinct seasonality in precipitation, making trip planning fairly predictable weather-wise. Dry weather prevails for most of the year, while the main, albeit very moderate, rainfall occurs in the winter and early spring months. Given the mild climate, snow is uncharacteristic for this region; any precipitation here falls primarily as rain.

The driest period in Santa Monica falls between May and October. During this time, rain is an extremely rare occurrence. In fact, in each of these months—May, June, July, August, September, and October—average precipitation is 0 mm. July stands out as an absolutely dry month, with an average of zero rainy days. In the other months of this dry season (May, June, August, September, October), there may be only one or two days with insignificant rainfall, which hardly affects the overall sunny outlook.

The "wetter" season, so to speak, begins in November and lasts until April. The wettest months in terms of rainfall are January, February, and March, with an average of 3 mm of precipitation each. March stands out with the highest number of rainy days—about 10. In January, February, and December, you can expect around 5 rainy days each. It is important to note that even in these months, the total amount of precipitation is low, suggesting a light drizzle or short showers rather than prolonged heavy rain.

When planning a trip to Santa Monica, it is worth considering its pleasant Mediterranean climate, though certain items will be useful year-round. Comfortable walking shoes for the famous promenade and the city are your main companion. Don’t forget sunscreen with a high SPF, sunglasses, and a hat, as the sun is strong here even on cooler days. The key principle for packing for Santa Monica is layering. Daytime and evening temperatures can vary significantly, and a light ocean breeze often provides a refresh, so the ability to easily add or remove a layer will come in very handy.

In the summer months, roughly from May to October, when the weather in Santa Monica is particularly warm and dry (average temperature 18-25°C, minimal rainfall), your suitcase should include light, breathable clothing: T-shirts, shorts, sundresses, and, of course, a swimsuit for the beach. In the evening or near the water, a light jacket, cardigan, or sweater may be useful as temperatures can drop. During the cooler period from November to April (average temperature 13-17°C), especially from January to March when light precipitation is possible (averaging 3 mm per month, up to 10 rainy days in March), you should add warm layers to your wardrobe: sweaters, jeans or thick trousers, as well as a lightweight waterproof jacket or a compact umbrella. Even in winter, daytime temperatures are often comfortable for walking, but it gets noticeably cooler by evening, reinforcing the importance of a layered approach to your outfit.
