    Los Angeles Weather for September 2021

    What's the Weather like in Los Angeles in September 


    Following in the footsteps of July and August, September remains extremely warm in Los Angeles, USA, with an average temperature of 21°C (about 69°F). The average daily high temperature gets up to around 27°C (around 81°F) and only gets as low as 14°C (about 57°F), meaning that evenings are still very pleasant. Las Vegas is in the desert, where temperatures can reach 35°C, so if Los Angeles isn't hot enough for you, Las Vegas is the place to go.


    The average rainfall in Los Angeles in September is just 5mm, with one rainy day on average, so don't worry if you leave your umbrella at home. More than likely, you won't need it with a 59 percent chance of getting a sunny day and a three percent chance of rain on any given day. Your chances of having a cloudy day are only nine percent on any day in September.

    Sunshine Hours 

    While fewer hours than the summer months, the average daily sunshine is still around 11 hours a day, plenty of time to get outside and enjoy Los Angeles. Even with the reduced hours of sunlight, you'll still want to bring and use sunscreen, hats and sunglasses.

    Average Sea Temperature 

    The average sea temperature is at a high of 20°C (about 68°F), so you can still spend a lot of time at the beach and in the water during this month. At this temperature, the water feels refreshing after spending time in the warm sun on the beach. This would be a good time of year to try out some watersports. Head to coastal areas such as Long Beach and Venice Beach to try snorkeling or scuba diving, and if you're a bit of a thrill seeker then why not try windsurfing or waterskiing!

    Dress Code 

    During the day, shorts and t-shirts are still appropriate and you might want a light jacket or sweater for the evenings, especially near the coast.
