Planning a trip to Puerto Vallarta in September, guys? Let's dive into what kind of weather you can expect! Knowing the climate conditions is super important to pack the right clothes and plan your activities. September in Puerto Vallarta is a unique time, offering a blend of sunshine, rain, and fewer crowds. So, let's break down the weather patterns and see how you can make the most of your vacation.

Temperature and Humidity

Let's talk about temperature and humidity because that's the first thing on everyone's mind! September is still part of the rainy season, so it's warm and humid. Expect average daytime temperatures to hover around the high 80s to low 90s Fahrenheit (around 31-33 degrees Celsius). The evenings cool down slightly, but not by much, remaining in the mid-70s Fahrenheit (around 24-25 degrees Celsius). This means you'll want to pack light, breathable clothing. Think cotton, linen, and moisture-wicking fabrics. The humidity can be quite high, often reaching levels of 70-80%. This can make it feel even hotter than the thermometer reads, so staying hydrated is crucial. Drink plenty of water, and consider bringing electrolyte drinks to replenish what you lose through sweat. Air conditioning will be your best friend, so make sure your accommodation has it! Despite the humidity, the warm temperatures create the perfect beach weather during the days when the sun is out.

Rainfall and Sunshine

Now, let's get into the nitty-gritty of rainfall and sunshine. September is smack-dab in the middle of the rainy season in Puerto Vallarta. You can expect rain on most days, but don't let that scare you off! The rain usually comes in the form of afternoon or evening showers and thunderstorms. These downpours can be intense but are often short-lived, typically lasting an hour or two. The rest of the day can still be sunny and beautiful. On average, Puerto Vallarta sees about 9-10 inches of rain in September. While this sounds like a lot, it doesn't usually rain all day, every day. The mornings are often clear and sunny, making them ideal for outdoor activities. You can expect around 6-8 hours of sunshine per day, which is still plenty of time to enjoy the beach, go snorkeling, or explore the town. When it does rain, it can be a welcome respite from the heat, cooling things down and making the vegetation lush and vibrant. Keep an eye on the weather forecast, but don't be surprised if it calls for rain every day – just be prepared for the possibility and plan your activities accordingly. You can bring a light rain jacket or umbrella. Don't worry so much about the rain, as it doesn't always ruin your vacation. Be flexible and take advantage of the sunny moments!

Sea Temperature

The sea temperature in September is fantastic for swimming and water activities! The water is warm, averaging around 84-86 degrees Fahrenheit (29-30 degrees Celsius). This makes it perfect for taking a dip in the ocean, snorkeling, diving, and other water sports. You can spend hours in the water without feeling chilly. Many people find the sea temperature in September to be one of the most enjoyable times of the year for water activities. The warm water also attracts a variety of marine life, making snorkeling and diving even more rewarding. You might see colorful fish, sea turtles, and other fascinating creatures. Whether you're a seasoned diver or just want to float around and relax, the sea temperature in September will not disappoint. Just remember to wear sunscreen, even when it's cloudy, as the sun's rays can still penetrate the water and cause sunburn. Bring your swimsuit and plan to spend a lot of time in the beautiful, warm waters of Puerto Vallarta!

Hurricane Season

It's important to be aware that September falls within hurricane season in the Eastern Pacific. While Puerto Vallarta doesn't often get direct hits from hurricanes, it can experience tropical storms and heavy rainfall during this time. Keep an eye on the weather forecast and heed any warnings issued by local authorities. It's always better to be safe than sorry. If a hurricane is approaching, follow the advice of hotel staff and local officials. They will provide guidance on what to do and where to go. Most hotels are well-prepared for hurricanes and have safety protocols in place. Travel insurance that covers hurricane-related disruptions is a good idea. This can help protect your investment if you need to cancel or change your travel plans. Even if a hurricane doesn't directly impact Puerto Vallarta, it can still cause heavy rainfall and rough seas. This can disrupt boat tours and other water activities. Be flexible with your plans and have alternative activities in mind in case the weather takes a turn for the worse. Don't let the possibility of a hurricane scare you away from visiting Puerto Vallarta in September. Just be informed, prepared, and flexible.

A light rain jacket or umbrella is also a good idea, as you can expect rain on most days. Comfortable walking shoes are essential for exploring the town and beaches. Sandals or flip-flops are perfect for the beach and poolside. Don't forget to bring sunscreen, sunglasses, and a hat to protect yourself from the sun. Insect repellent is also a good idea, as mosquitoes can be active, especially after rain. A reusable water bottle will help you stay hydrated throughout the day.
