Guatemala is a land of smoking volcanoes, Maya ruins and colorful highland markets. But even paradise has its problem months. If you’re planning a trip, understanding the worst time to visit Guatemala can save you from relentless rain, washed-out roads, tropical storms and disrupted plans.

Understanding Seasons in Guatemala

Guatemala has two main seasons rather than four:

• Dry season (roughly November–April): Sunny skies, lower humidity and fewer rainy days – usually considered the best time to visit. 

• Rainy season (roughly May–October): Afternoons often bring heavy showers, especially in the highlands and jungle regions like Tikal.

Layered on top of that is the Atlantic hurricane season, which runs from June to November, with a particular spike in activity around September and October. 

So, When Is the Worst Time to Visit Guatemala?

From a practical travel point of view, the worst time to visit Guatemala is usually September and October. Here’s why those months are the most problematic:

1. Peak of the rainy season – Expect frequent, intense showers that can last for hours.

2. Higher risk of tropical storms and hurricanes, especially affecting the Caribbean coast and lowlands.

3. Landslides and flooded roads in mountain regions can make bus travel slow or even impossible.

4. Cloudy skies and poor visibility can spoil volcano hikes and sunrise views over Lake Atitlán.

If your dream trip includes multi-day treks, remote villages or overland crossings, these months bring the highest chance of cancellations and long, muddy travel days.

Weather Warnings: Rain, Heat and Humidity

1. Heavy Rain and Muddy Trails (May–October)

Rainy season doesn’t mean constant storms, but it does mean:

• Clear mornings followed by dramatic afternoon downpours

• Slippery hiking trails on Acatenango and other volcanoes

• Occasional flooding and road closures in rural areas

If you’re hoping to photograph bright cobblestone streets in Antigua or hike among volcano views, persistent cloud cover and rain can be a serious disappointment.

2. Hurricane Season Risk (June–November)

While direct hurricane hits are not an everyday occurrence, Guatemala can be affected by:

• Torrential rain from passing tropical storms

• Swollen rivers and landslides in highland regions

• Disruptions to domestic flights and boat connections

The Caribbean side and northern lowlands are more vulnerable during these months, and September–October are considered the most unstable for weather-dependent itineraries.

Crowds, Costs and Holidays: Hidden “Worst Times”

Bad timing isn’t only about storms. It can also be about too many people and higher prices.

Christmas, New Year & Easter: Beautiful but Overbooked

• Late December to early January and Holy Week (Semana Santa) around March/April are among the busiest periods to visit Guatemala.

• Antigua, Lake Atitlán and main tourist hubs fill up quickly.

• Hotels, shuttles and volcano hikes should be booked well in advance.

These festivals are culturally spectacular but can feel like the “worst time” if you hate crowds or are travelling on a tight budget.

Safety:  “Worst Time”

Before you go, it’s smart to:

• Check your government’s latest travel advice

• Register your trip if your country offers that service

• Work with reputable local operators who track conditions daily

Region by Region: When Things Get Tricky

Antigua & The Highlands

• Worst time: September–October

• Why: Cloudy skies hide volcano views, rain can wash out trails, and cooler damp evenings feel less comfortable in colonial houses not designed for heavy storms.

Lake Atitlán

• Worst time: Peak rainy season (June–October), especially September

• Why: Afternoon storms whip up waves on the lake, boat schedules become unpredictable, and paths between villages can be muddy and slippery.

Tikal & the Northern Jungle (Petén)

• Worst time: Late May–September

• Why: Heat plus humidity, frequent rain, muddy jungle trails and more mosquitoes. Climbing temples in full sun and steam is tough on the body.

Caribbean Coast & Rio Dulce

• Worst time: September–October

• Why: Strongest influence from Atlantic hurricane season, risk of heavy storms and rough seas, which can disrupt boat trips and island excursions.

Can You Still Visit in the “Worst Time”?

Surprisingly, yes if you know what to expect.

Travelling in the rainy or hurricane-risk months often means:

• Lower prices on hotels and tours

• Fewer crowds at famous spots like Tikal or Semuc Champey

• Lush green landscapes that photographers love

If you must travel in September or October, aim for:

• Flexible itineraries with buffer days

• Destinations less affected by storms on your specific year’s forecast

• Travel insurance that covers weather-related disruptions

How to Avoid the Worst and Enjoy the Best

There’s no single “do not go” month for everyone, but if your goal is comfortable weather, clear views and smooth logistics, avoid September and October, be cautious during June–November hurricane season, and think twice about peak holiday crowds unless festivals are your main reason to travel.
