If you look at the annual weather of all the popular coastal cities in Mexico, they are all going to be very similar at first glance. You’ll see an average annual temperature of around 26°c (80f) no matter if you’re looking in Cancun, Puerto Vallarta or Mazatlán. However, there are many other factors (like average rainfall, humidity, nightly lows, etc.) that will dramatically change how you experience those temperatures.
When we started doing research on where to spend the winter in Mexico, we began the search not by studying temperatures, but by studying humidity levels. Humidity is the one factor that can either make the exact same temperature feel wonderful or sufferable.
Our goal was to find a coastal city in Mexico with less humidity, so that we could spend more time enjoying the outdoors instead of always hiding inside with the AC.
I actually enjoy some heat and humidity but spending the last 2 years in South East Asia where the humidity never drops below 80% (and can commonly reach 100%), we were looking for a climate that wasn’t so oppressive.
Mexico has always been one of my favorite countries in the world and I have spent time in almost every major coastal city, but I believe I have now found my favorite climate out of all of them: Mazatlán.
Now, me telling you that Mazatlán has the best weather in Mexico is like telling you a particular flavor of ice cream is the best. It’s all subjective and completely personal. However, I’m going to tell you in detail WHY I think it’s the best weather, along with some statistics and even some comparisons to other Mexican cities. That way, you’ll have all of the information to make a decision on where you might think has the best weather.
I will compare Mazatlán to: Cabo, Huatulco, Puerto Vallarta, Manzanillo and Cancun (which also includes Playa Del Carmen and Tulum.)
Mazatlán has one of the best coastal climates in all of Mexico, especially for snowbirds who visit for half the year. The winters are sunny and dry with lower humidity, almost a 0% change of rain, and cooler refreshing night temperatures.
Let’s look at some quick Mazatlán Weather stats:
- 2800+ hours of annual sunshine
- Average temperature of 24°c (75°f)
- Average humidity between 65%-70%
- 40 days of rainfall
Wikipedia tell us: “Mazatlán has a tropical savanna climate bordering a hot semi-arid climate, with a marked and rather long dry season.”
Mexican City Closest to Mazatlán’s Weather:
= Puerto Vallarta
Puerto Vallarta is almost Mazatlán’s twin when it comes to annual weather. They have the most similarities when compared to the other coastal hot-spots.
Here are the main differences:
Puerto Vallarta is a few degrees warmer at night, has more rainy days, and is around 10% more humid on average. For people who like warmer climates, a greener environment, and aren’t bothered by humidity, Puerto Vallarta is a great choice.
For people who value those cooler nights and a drier climate, Mazatlán is the best pick.
Average Humidity in Mazatlán
Thank goodness the humidity levels in Mazatlán, especially in the winter months, are very tolerable. Yes, the summer months are a different story, but we’ll get to that.
The average annual humidity level in Mazatlán is 65%-70%. (I found 2 conflicting data points. One claims 65% while the other claims 70%)
In the winter you will find it as low as 55% and in the summer it can creep up over 85%.
We could only find TWO other coastal vacation cities in Mexico that had lower annual humidity than Mazatlán – Cabo San Lucas and Puerto Peñasco.
The dry climate of Cabo
Don’t get me wrong, Cabo and Puerto Peñasco are beautiful in their own way, but they are a desert climate. The moment you’re not in a resort that planted and waters its own palm trees and grass, all you see is brown dust. Personally, I like a city with a little more natural green in it.
Puerto Peñasco is extremely dry
Now Mazatlán is kind of in-between when it comes to flora. It’s not as dry as Cabo, but it’s not as lush as the Yucatan. With lower humidity and lower rainfall, you get drier climates and not as much green vegetation.
The summers here in Mazatlán will be greener, while the winter tends to ‘brown’ up a bit.

Humidity in Mazatlán compared to other coastal cities in Mexico
Cabo San Lucas 57%
Puerto Vallarta 77%
I am writing this blog in Mazatlán in November just when the humidity levels are dropping from September. It’s SO refreshing to be able to go outside without hitting that WALL of wetness. It makes it much easier to walk around without being completely soaked in sweat from head to toe. In my opinion, it’s one the nicest things about Mazatlán compared to other Mexican cities I have visited or lived in. I am really looking forward to the next 4 to 5 months where the humidity will drop even lower.
Now let’s cover the high humidity. In the summer between July and September, the wetness in the air is out of control high, or as they call it ‘oppressive’ and ‘miserable’.
Now, if we compare the annual humidity chart of Mazatlán with the charts of Cancun and it’s almost twin-sister city Puerto Vallarta, we can easily see that Mazatlán has FAR more dry and comfortable days. (Shown in green and blue.) You can hardly see any blue or green on Cancun’s chart, and Puerto Vallarta doesn’t have much either. Mazatlán has a large chunk of the year with very comfortable levels of humidity, which is one of its best features!
Average Annual Rainfall in Mazatlán
If you came to Mazatlán for 6 months, let’s say November to April, you might only see a handful of rainy days during your entire half-year stay. From February to May specifically, you might not even see ONE rainy day.
This type of dry weather during the winter is perfect for snowbirds and vacationers because it almost guarantees your holidays won’t be ruined by rain. There is plenty of sunshine and not a lot of cloud cover, providing a lot of bright and sunny days.
Now, the summer and start of fall is a different story. There are 3 months in particular that have a LOT of cloudy days and rainfall: July, August and September. Most snowbirds leave for the summer months but there are still plenty of expats and domestic tourists that visit between July and September.

When you ONLY look at the daily average temperatures, all the cities really look the same, however, each one ‘feels’ completely different. That is why I have learned to look at other factors like wind speed, sunshine hours, humidity, rainfall, and even water temperatures.
For people just visiting for a week, it’s much less crucial to know these details, but if you are considering re-locating they details can make or break a decision.
Why I think Mazatlán has the best weather
- It has the coolest winters. With the average being 15°c in the night and 26°c during the day, it’s such a nice break from intense heat 24/7. It also helps keep expensive A/C bills lower because it doesn’t need to be cranked all the time.
- For 6 months of the year, it hardly rains at all. Just warm and dry weather with plenty of sun.
- For half of the year you can exercise outside, go for long walks, and even eat outdoors without melting into a puddle.
- Mould and mildew levels are lower due to lower average humidity in the air.
- The water temperature is still incredibly warm in the fall season, just before winter sets in. You might find it anywhere from 26-30°c until December.
Former Realtor and hoarder, turned minimalist and loving every minute of it.
I sold 90% of my belongings, including my home, and started on my journey around the globe.
Choosing a life of adventure gave me so much more than I ever expected. Through documenting my journey I created a travel brand and blog that gets over 1 million visitors per year and growing. I published a book that helps others embrace minimalism and declutter their life. I started to speak out about issues like social media addiction and comparison that are plaguing our generation. I was finally able to be myself.
What does life look like as a minimalist travel blogger? I live 6 months of the year in an RV on the lake. The other 6 months I travel the world with my husband, always choosing new countries to explore. I write articles that help make travel more accessible and fun for curious readers.
I show others the beauty of ‘less is more’ and the power of being real in a staged world.
