When to Visit Each RIU Destination: A Season-by-Season Guide
RIU's portfolio spans Caribbean beaches, Pacific coastlines, Central American rainforest coasts, and downtown hotels in major cities, and each of those settings runs on its own calendar. A date that's ideal for Cancún can be the wrong week for Costa Rica, and a city stay follows a completely different logic than a beach resort. This guide breaks down the climate and travel patterns for each region so you can match your dates to the destination rather than the other way around.
Mexico and the Caribbean: dry season vs. hurricane season
The Atlantic and Caribbean side of RIU's map, Cancún, Riviera Maya, Costa Mujeres, Punta Cana, Jamaica, and the Bahamas, shares a tropical pattern with a defined dry season roughly from December through April and a wetter, warmer season from June through November that coincides with the Atlantic hurricane season. December to April is the most reliable window for sun and lower humidity, which is also why it's the busiest period at properties like Hotel Riu Palace Kukulkan and Hotel Riu Caribe in Cancún, Hotel Riu Palace Riviera Maya and Hotel Riu Lupita near Playa del Carmen, Hotel Riu Dunamar in Costa Mujeres, Hotel Riu Palace Macao and Hotel Riu Bambu in Punta Cana, Hotel Riu Palace Jamaica in Montego Bay, and Hotel Riu Palace Paradise Island in Nassau.
September and October carry the highest statistical risk of tropical storms across this whole region, so travelers with flexible plans often shift toward November or late April to early June, shoulder months that still offer warm water and fewer crowds. Humidity and short afternoon showers are normal even in the dry months, so pack for both.
Pacific Mexico and Aruba: a different rhythm
The Pacific coast of Mexico, Puerto Vallarta, Cabo San Lucas, and Mazatlán, follows its own pattern, drier and milder from roughly November through May, with a hotter and more humid rainy season from June into October. Hotel Riu Palace Pacifico and Hotel Riu Jalisco in Puerto Vallarta, Hotel Riu Palace Baja California in Cabo San Lucas, and Hotel Riu Emerald Bay in Mazatlán are all most comfortable in that cooler stretch of the calendar, especially for travelers planning outdoor excursions.
Aruba sits outside the main hurricane belt and has one of the driest, most consistent climates in the southern Caribbean, so Hotel Riu Palace Aruba is a reasonable choice almost any month, with slightly higher visitor numbers around the winter holidays and again in the European summer.
Costa Rica and Panama: watch the rain, not just the heat
Both countries are tropical year-round, so temperature swings less than rainfall does. Costa Rica's Pacific coast, where Hotel Riu Palace Costa Rica and Hotel Riu Guanacaste sit in Guanacaste province, has a pronounced dry season from roughly December to April and a green season from May to November when afternoon rain is common but mornings are often clear. The dry season is the easiest for beach days and excursions, while the green season brings lower humidity swings, lusher landscapes, and fewer visitors.
Panama's Pacific side, home to Hotel Riu Playa Blanca in Rio Hato, follows a similar two-season pattern: a dry stretch roughly December through April and a wetter period the rest of the year. Rain in both countries tends to arrive in bursts rather than all day, so it rarely cancels a full day of plans.
RIU Plaza city hotels: timing a city break differently
RIU's city hotels in destinations such as New York, Miami, Chicago, San Francisco, Madrid, Berlin, and Dublin don't follow a beach calendar, they follow each city's own seasonal and event calendar. North American and European cities see their coldest, shortest days in December through February and their most crowded, priciest stretches around major holidays, festivals, and conference seasons, which vary by city.
Spring and autumn are generally the most comfortable windows for walking-heavy city itineraries in most of these destinations, with milder temperatures and typically lighter crowds than peak summer. Miami is the exception worth noting: it's warm nearly year-round, so its busiest season runs opposite to the northern cities, peaking in winter when travelers are escaping colder climates.
