When to Visit Each RIU Destination: A Season-by-Season Guide
RIU's portfolio ranges from adults-only beach palaces in the Caribbean to city hotels in Madrid or Chicago, and each region runs on its own calendar. A month that's peak season on the Yucatán coast can be the rainiest stretch in Costa Rica, or the coldest week in a Riu Plaza city. This guide breaks down the main climate patterns by region so you can match your dates to the destination rather than the other way around.
Mexico's Caribbean Coast: Cancún, Riviera Maya, Costa Mujeres
Cancún, Costa Mujeres and Playa del Carmen share a tropical climate with a clear high season from December through April, when humidity and rainfall drop and days are consistently sunny. This is also when hotels like Hotel Riu Palace Kukulkan, Hotel Riu Cancun and Hotel Riu Caribe in Cancún, or Hotel Riu Palace Riviera Maya and Hotel Riu Lupita in Playa del Carmen, run busiest.
June through November is the Atlantic hurricane season. Storms don't hit every week, but the risk of a tropical system affecting travel plans is real, and afternoon downpours become more frequent even on calm days. Many travellers still visit in this window for quieter beaches and easier direct booking availability, accepting the trade-off.
Hotel Riu Latino in Cancún and Hotel Riu Dunamar in Costa Mujeres follow the same seasonal pattern as the rest of the coast. If your trip depends on calm seas or specific weather, aim for the December-to-April window and book with enough lead time, since this is when rooms fill fastest.
Punta Cana, Jamaica and the Bahamas
Punta Cana, Montego Bay and Nassau sit on the Atlantic side of the Caribbean and follow a similar rhythm to Mexico's Caribbean coast: dry, mild months from roughly December to April, and a warmer, wetter, storm-prone season from June to November.
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 all sit directly on the coast, so wind and swell conditions matter more here than inland. Winter months bring the calmest water for swimming and snorkeling.
Aruba, home to Hotel Riu Palace Aruba, is the outlier in this group. It sits outside the main hurricane belt and has one of the most stable, dry climates in the Caribbean year-round, which makes it a reasonable choice even in months when other islands are riskier.
Mexico's Pacific Coast: Puerto Vallarta, Cabo San Lucas, Mazatlan
The Pacific side of Mexico runs on a different calendar than the Caribbean side. Puerto Vallarta and Mazatlan have a rainy season roughly from June to October, with the driest, most reliably sunny stretch from November to May. Hotel Riu Palace Pacifico and Hotel Riu Jalisco in Puerto Vallarta, and Hotel Riu Emerald Bay in Mazatlan, are busiest in that dry window.
Cabo San Lucas, where Hotel Riu Palace Baja California sits, has a desert climate that's drier overall than the rest of the Pacific coast, with hurricane risk concentrated in a shorter late-summer to autumn window rather than spread across several months.
Whichever Pacific destination you choose, water temperature and visibility for snorkeling or diving tend to be best in the winter and spring months, though air temperatures are comfortable most of the year.
Costa Rica and Panama
Costa Rica's Guanacaste region, home to Hotel Riu Palace Costa Rica and Hotel Riu Guanacaste, has two seasons rather than four: a dry season from roughly December to April with almost no rain, and a green season from May to November with more frequent but often short afternoon showers. Wildlife viewing and hiking are generally easier in the dry season, but the green season brings lower humidity in the mornings and lusher scenery.
Panama's Pacific coast, where Hotel Riu Playa Blanca sits in Rio Hato, follows a similar dry-and-green pattern to Costa Rica, though it tends to be less extreme, with a shorter, milder rainy season.
Both destinations are warm year-round, so the choice between dry and green season is more about rain tolerance and activity plans than temperature.
Riu Plaza City Hotels: New York, Miami, Chicago, San Francisco, Madrid, Berlin, Dublin
The Riu Plaza city hotels sit in destinations with genuine four-season climates, so timing depends on what you're there to do rather than a single high season. New York, Chicago and Berlin have cold winters and warm, sometimes humid summers, with spring and autumn offering the most comfortable walking weather for sightseeing.
Miami runs opposite to the others in this group: winter is the dry, mild high season for visitors, while summer brings heat, humidity and a higher chance of afternoon storms.
San Francisco has one of the mildest year-round climates of the group, with relatively small temperature swings between seasons, while Dublin stays cool and unpredictable in any month, with slightly drier stretches typically falling between late spring and late summer. Madrid runs hot and dry in July and August and cooler the rest of the year, making spring and autumn the more comfortable choice for a city break.
