Precipitation is practically non-existent during this period.

Spring and autumn represent pleasant transitional periods with comfortable temperatures.

One of the main features of the weather in Long Beach is the long dry season, which covers the summer and autumn months when rain is a great rarity. Even during the winter months, which are considered wetter, the amount of precipitation remains low, contributing to predominantly clear weather and creating excellent conditions for outdoor activities and exploring the city.

Long Beach enjoys a comfortable temperature regime throughout the year, with distinctly warm summer months and mild winters. The hottest period is usually August, when the average temperature reaches 24.6°C, and daytime highs can regularly rise above 30°C. July and September are also very warm, with average temperatures around 24.0°C and 23.8°C respectively, making them ideal for enjoying the sun. The coolest months are considered to be February (average temperature 13.6°C, minimum nightly around 7.8°C) and January (average temperature 13.7°C, minimum nightly around 8.2°C), although even at this time, the weather remains quite mild and pleasant for visiting.

The summer months, from June to September, in Long Beach are characterised by pleasantly warm and predominantly sunny weather. Daytime temperatures during this period often range from 26°C to 30°C, creating wonderful conditions for beach holidays and various outdoor activities. Nights bring refreshing coolness, with temperatures dropping to 16-19°C. Winter, covering December, January, and February, is notable for its mildness. Average daytime temperatures usually stay in a comfortable range around 19-20°C, while at night they may drop to 8-9°C. This means that even in the coldest months, there are no severe frosts here, and the weather remains favourable for walking and sightseeing.

One of the characteristic features of the Long Beach climate is the noticeable diurnal temperature variation. The difference between daytime highs and nightly lows throughout the year averages 10-12°C. This means that even after a hot day, evenings and nights can be noticeably cooler. Therefore, a light jacket or sweater can be very useful for evening walks, especially during transitional seasons as well as in winter. Such fluctuations contribute to a more comfortable rest at night after warm sunny days.

Precipitation in Long Beach is distributed unevenly throughout the year, with a clearly defined long dry season and a wetter, yet still moderate, winter-spring period. The summer and autumn months are practically devoid of rain, while the main, albeit small, part of annual precipitation falls in the period from late autumn to early spring. Given the mild climate, snow is an extremely rare phenomenon here, and precipitation falls predominantly in the form of rain.

The driest period in Long Beach is the interval from May to October. During these months, rain is a great rarity. July stands out in particular, when on average there is not a single rainy day and no precipitation is recorded at all (0 mm). June, August, and September are also practically devoid of precipitation, with one or fewer rainy days and 0 mm of rainfall. Even in May and October, the number of rainy days does not exceed two, and precipitation is minimal.

The wetter season falls on the months from November to April. The highest amount of precipitation and rainy days is observed in March, when an average of 3 mm of precipitation falls, and the number of days with rain reaches nine. January, February, and December also bring some moisture – about 2 mm of precipitation and approximately 5 rainy days in each of these months. However, even in the "wettest" period, the amount of precipitation remains low, which indicates the predominantly light nature of the rains and the preservation of a large number of sunny days.

When planning a trip to Long Beach, it is worth betting on a versatile wardrobe that will allow you to feel comfortable throughout the day. Since the weather here delights with sunshine all year round, do not forget sunscreen, sunglasses, and a hat. The foundation of your luggage should be comfortable shoes for walking around the city and the waterfront. Given the noticeable diurnal temperature fluctuations, when evenings can be perceptibly cooler even after a warm day, the principle of layering in clothing will be your best helper. A light jacket, cardigan, or sweater will come in handy at almost any time of the year for evening outings.

In the summer months, from June to September, as well as on warm days of late spring and early autumn, your suitcase should be filled with light and breathable clothing. Cotton t-shirts, shorts, sundresses, skirts, and, of course, a swimsuit for enjoying the beaches of Long Beach will be most appropriate. Precipitation during this period is a great rarity (on average 0 mm from June to October), so you likely won't need an umbrella. The main thing is sun protection and comfort in warm weather, when daytime temperatures can reach +26°C to +30°C.

In winter, from December to March, and on cool days of the off-season, it is worth adding a few warmer items to your wardrobe. Jeans or trousers, long-sleeved shirts, sweaters, and a light jacket (for example, a windbreaker or fleece jacket) will ensure comfort during walks, especially when night temperatures drop to +8°C. In the period from January to March, short-term rains are possible (on average 5-9 rainy days per month with precipitation of 2-3 mm), so a small folding umbrella or a light waterproof jacket may be useful, although heavy and prolonged rainfall is unlikely here.
