Puerto Vallarta has two seasons and only one of them shows up in the brochures.
From November to May the sky is blue every day and the hills are the colour of straw. Then the first storm arrives in June, and within two weeks the whole Sierra Madre goes green.
The rain here is not a grey week in a jacket â it is a loud, dramatic hour in the late afternoon, and mornings that are clear, washed and quiet. This is how to use it.
What the green season actually is
Puerto Vallarta has two seasons and only one of them shows up in the brochures. From November to May the sky is blue every single day, the hills are dry, and the grass on the mountainsides is the colour of straw. Then, somewhere around the middle of June, the first storm arrives, and within two weeks the entire Sierra Madre turns green.
Locals call it temporada de lluvias. Everyone else calls it the green season, and it runs roughly from mid-June to mid-October. It is the least-booked part of the year and, for anyone who came here to look at things, it is quietly the best-looking one.
What the rain is really like
The mistake visitors make is picturing a grey week in a rain jacket. That is not what happens here.
Most days in the green season start clear. The sun is out in the morning, the bay is calm, and nothing about the sky suggests weather. The clouds build over the mountains during the afternoon, and the rain usually falls late in the day or overnight â hard, loud, dramatic, and over in an hour or two. By morning the streets are dry again and the air has been washed clean.
That pattern is the whole trick to planning a green-season trip: do things in the morning. Ride, paddle, surf, hike early, and treat the afternoon as the part of the day for lunch, a nap and watching the storm roll across the bay from somewhere with a roof.
What the rain does to the landscape
The transformation is not subtle. In May the hills behind the city are brown and the riverbeds are mostly rock. By August the same hills are covered in vegetation so dense you cannot see the ground, the RĂo Cuale is running full, and the waterfalls in the Sierra Madre â the ones that are a trickle in April â are actually falling.
A few things worth seeing specifically because it rained:
- The mountains from any dirt road. The colour is the point. Green on green on green, with clouds sitting in the folds of the sierra in the morning.
- The rivers. Crossings that are ankle-deep in the dry season have real water in them, which is more fun and more photogenic.
- The waterfalls. Everything running in the mountains behind Vallarta is at its strongest between July and September.
- The sunsets. Clouds are what make a sunset. Dry season gives you a clean orange sun dropping into the ocean; green season gives you the whole sky on fire.
The best way to see it
Green season rewards getting out of town, because the change happens in the mountains rather than on the beach. An ATV or a dual-sport bike on a mountain route is the most direct way to be inside all of it â dirt roads, river crossings, the smell of wet jungle, and views that simply do not exist four months earlier.
The routes above the city, past the hot springs and toward the small towns of the sierra, are where the contrast is biggest. Our Sierra Madre ATV Adventure and the longer Edén Private Tour both spend most of their time up there.
On the water, the mornings are glassy and the sea is at its warmest of the year â high twenties Celsius, low eighties Fahrenheit, no wetsuit, no hesitation getting in. It is also the surf season on this coast, which we wrote about separately.
What to plan around
- Book mornings. Not a suggestion, a strategy. Tours run early for a reason.
- Humidity is real. It is warmer and stickier than winter. Drink more water than you think you need and take the shade seriously.
- Mud happens. On an ATV or a dirt bike you will get dirty. Wear clothes and shoes you do not care about, and bring a change for afterwards.
- Rivers rise fast. After a heavy night, some mountain crossings need judgement. If a guide changes the route, that is the system working.
- It is also hurricane season. Direct hits are rare and always forecast days ahead. Keep an eye on the weather in the week before you travel and keep your plans flexible.
- The city is quieter. Fewer people, easier restaurant tables, lower hotel rates. That is the trade you are making, and it is a good one.
Go while it is green
The window is real but short â by late October the rain stops, and within a few weeks the hills start fading back toward gold. If you are here between June and October, take one morning and go up into the mountains. It is the version of Puerto Vallarta that most visitors never see, and it only exists because it rains.
