Thinking about booking Riviera Maya or Cancún?

Before you dive in and book on a whim, there are two things you need to know:

• Wet season
• Sargassum season

If you’re picturing flawless beach days, they matter.

But if you’re chasing cenotes, Chichén Itzá and better package prices, the so-called “low season” can actually work in your favour.

Let’s break down the best months to visit — and when you can grab a bargain.

Wet Season Riviera Maya & Cancún

The wet season runs from late May through to October (sometimes into early November).

Despite what some charts say, May is often still one of the driest months. The proper downpours tend to creep in towards the end of the month.

Going during wet season doesn’t mean constant rain. It just means you’re rolling the dice slightly.

You might get blazing sun all week…
Or you might get the occasional day that feels like a wet weekend in Bognor.

Hurricane season runs from June to November, with September and October carrying the highest risk.

That doesn’t mean panic — but if you’re travelling from the UK and want the safest bet? Those are the months we’d personally avoid.

How Much Does It Actually Rain?

On average, the Riviera Maya and Cancún see around 40 days of rain per year.

Even during wet season, that usually works out at roughly six days per month — and most of those showers are short and sharp.

Think 10–30 minutes. Not all-day misery.

One minute we were supping Mango Joe cocktails in the pool, listening to Raul’s ten songs on a loop in blazing sunshine.

The next? Absolute monsoon.

I was shielding my drink with a cap like it was a national emergency.

Ten minutes later — blue skies again. Like nothing had happened.

That’s Caribbean rain for you.

Don’t Trust the Weather Apps

The classic mistake? Checking the forecast two weeks before you go and panicking.

Weather apps love to slap a thundercloud icon on the whole day. It looks like England in January — Wet, Wet, Wet.

In reality?

It might rain for 20 minutes. Then it’s back to blazing sun.

We’ve seen full days forecast as “thunderstorms” that turned out to be one dramatic downpour before lunch.

The only thing worth properly watching is tropical storm or hurricane warnings. That’s when plans genuinely change.

Sargassum Season Riviera Maya & Cancún

Sargassum (seaweed) season typically runs from March/April through to October — broadly overlapping with wet season.

If your dream holiday is powder-white sand and crystal-clear water every single day, this matters.

December, January and February are usually the safest months for pristine beaches. But — as always — the price reflects it.

The Pacific coast of Mexico isn’t affected, so that’s another option entirely.

I once saw someone in a Facebook group blaming TUI for advertising a “beach holiday” when the beach was unusable.

Two weeks earlier? Pristine.
Two weeks later? Pristine again.

A couple of tropical systems dragged in a mass of sargassum. That’s nature — not false advertising.

It can be frustrating if it hits during your exact two-week window. But it isn’t permanent, and it isn’t predictable down to the day.

Why Is There Suddenly So Much Sargassum?

Scientists don’t have one single smoking gun — but several factors are likely at play.

There’s something called the Atlantic Sargassum Belt, stretching thousands of miles from Brazil to West Africa. For years, it mostly stayed out at sea.

Over the last decade, though, it’s been drifting into the Caribbean in much larger volumes.

Warmer ocean temperatures, fertiliser runoff from rivers (particularly the Amazon), and deforestation are all thought to be contributing.

In 2022, NASA recorded the sargassum belt at nearly 6,000 miles long.

So no — it didn’t suddenly “appear.”
But the scale of it has definitely increased.

How Mexico Is Dealing With the Sargassum Problem

Tourism is massive in this part of Mexico, so this isn’t being ignored.

The government has deployed the Navy, installed floating sea barriers, and funded huge beach-cleaning operations.

If you’ve been, you’ve probably seen them — teams out at sunrise with tractors, forks and wheelbarrows, fighting a battle that resets overnight.

Resorts are also building offshore barriers and temporary sea walls. They’re not exactly Instagram-perfect, but they do help reduce what reaches the shore.

Over 22 million passengers passed through Cancún Airport in 2021 alone, with numbers continuing to climb. If sargassum became permanent and overwhelming, tourism would take a hit.

That’s why it’s being tackled aggressively.

Isla Mujeres, Holbox & Cozumel: Less Affected (But Not Immune)

Isla Mujeres, Holbox (car-free) and Cozumel are typically less affected by sargassum than the mainland Riviera Maya. The Cancun hotel zone is also a pretty safe bet

That doesn’t mean they’re completely immune — but they’re often a safer bet during peak seaweed season.

The trade-off?

Higher prices and slightly more effort to get there.

If beach quality is your top priority, these islands are worth considering.

Cheaper Months for Package Holidays to Mexico

When you go makes a big difference to the price. The shoulder seasons are usually your best bet for decent weather & budget.

That’s not to say you won’t get cracking weather in October/November, plenty do, and they enjoy 2 weeks of sunshine. It just depends on how much risk you want to take. Knowing our luck? We’d have a cat 4.

From our own bookings, the gap between peak winter and shoulder season can be eye-watering.

For example, El Dorado Seaside Suites was nearly £2,000 more expensive in January compared to early December (based on two adults, 14–15 nights).

We saw similar swings between early April and late April / early May — around £1,800 difference for the same hotel.

That’s not small change.

Generally speaking:

• Late April / early May
• Early December

…tend to be noticeably cheaper than peak winter months.

You’re trading a bit of weather certainty for serious savings.

Our Sargassum Experience in April/May

We travelled from April 26th to May 10th — right as sargassum season was kicking in.

We had a few heavy days.

In some ways, it was oddly fascinating watching nature roll in waves, completely unbothered by tractors and teams trying to clear it.

The beach crews worked relentlessly — forks, wheelbarrows, tractors from sunrise. Proper graft.

But against nature at full force? It’s a losing battle some days.

Out of fourteen nights, the beach was probably best avoided on three.

The rest of the time? Absolutely fine.

And on heavier days, you adjust:

• Hit the pool
• Book a cenote
• Explore a nearby town
• Spa day
• Margarita

If you see the beach teams working, a few pesos, drinks or snacks go a long way. They’re fighting Goliath every morning. 

Final Thoughts on the Best Time to Visit Riviera Maya & Cancún

If you want the safest bet for near-perfect beach weather:
👉 December to early April

If you want better prices, but be prepared to play sargassum roulette. The rain doesn’t kick till the end of May, as shown in the graph earlier in the post.
👉 Late April, May

If you’re travelling from the UK and want to minimise hurricane risk, we’d personally avoid September and October. And if you’re already planning ahead, here’s what currency we actually recommend taking to Mexico – What currency to take to Mexico from the UK

Sargassum?

It’s unpredictable. Some weeks are pristine. Some weeks aren’t. But it’s rarely a full two-week disaster.

And if you do get a few seaweed days?

Hit the pool. Book a cenote. Explore. Grab a margarita. Just don’t forget — tipping is part of the culture here – Tipping in all-inclusive Mexico

Mexico very rarely disappoints.
