In Esperanza, when a December evening comes, the sound of a parranda, neighbors moving porch to porch with guitars, cuatros and maracas, fills the open-air restaurants along the malecon. Wild horses wander the road at dusk as if they were part of the party. December brings Vieques its dry season, when guesthouses glow with Christmas lights and daytime stretches into long, quiet beaches, which suits anyone thinking of a beach vacation on that little island off Puerto Rico’s east coast.
What is the weather like in Vieques in December?
December in Vieques is warm, breezy and noticeably drier than the autumn months, with sunny stretches broken by short passing showers.
| Month | Average high (°F) | Average low (°F) | Rain days | Sea (°F) |
|---|---|---|---|---|
| November | 80.0 | 77.1 | 13.4 | 84.4 |
| December | 78.5 | 76.0 | 8.1 | 81.9 |
| January | 77.2 | 74.9 | 5.8 | 80.8 |
Early hours arrive gentle and glowing, yet come noon the sunshine beats down hard enough to leave you craving a hat, some shade and a dip. Afternoons stay comfortable thanks to the trade winds, which keep the heat from feeling heavy on the beach. Come evening, the air stays soft enough to eat outdoors in short sleeves, maybe adding something light when the wind strengthens by the shore.
Rain tends to arrive as quick showers that sweep across the island and move on, often leaving a rainbow over the hills. This month, it is rare to get a day of serious heavy rain. When one does come, it usually clears within an hour or two, so a wet morning does not mean a lost day.
The light in December is gentle and golden, and the days are a little shorter than in summer. Sunsets over the Caribbean side arrive early in the evening, which suits a drink at the waterfront in Esperanza. Pack for sun first and showers second.
Can you swim in Vieques in December?
The Caribbean is certainly warm enough in December for a long, comfortable swim, just a touch chillier than it was in the fall.
The south coast beaches, such as Sun Bay, usually have gentler water than the exposed north shore, where winter swells from the Atlantic can make the sea rougher. Day to day and beach to beach, the water shifts, so take a look at it before getting in. Check local conditions and follow any posted warnings before entering the water.
Red Beach and Blue Beach count as two of Vieques’ best-loved places, perfect for floating in clear water and, on calm days, for snorkeling. Pack a mask, a rash guard and sunscreen, because the sun stays strong even if the breeze feels cool.
Families and nervous swimmers do best at the beaches that look gentle on the day, and with children it helps to stay close to shore. Sargassum can occasionally gather on some shores, though it is more a spring and summer chance.
What to do in Vieques in December
December on Vieques is the holiday season in a small-island key. Puerto Rico’s Christmas season runs from late November into mid-January, and you may hear parrandas, hear holiday music drifting from bars and see lights strung across guesthouses and shops. On Three Kings Day on January 6 the season continues, but December already has the spirit, with pasteles (plantain and meat parcels wrapped in leaves), lechon asado and coquito, the coconut-and-rum drink, on menus and in family kitchens.
The dry season also suits the outdoors. Mornings are good for long walks on empty sand, and afternoons for swimming and reading in the shade. The island is quiet in the evenings, so most days end with dinner at an open-air restaurant, a stroll and a look at the stars.
Mosquito Bay at night
The island’s bioluminescent bay, known as Mosquito Bay (Puerto Mosquito), is its main attraction after dark. You head out with a local guide leading the way, traveling by kayak or electric boat, and whenever a hand or paddle stirs the water, tiny creatures answer with a blue glow. For the brightest shine, plan your visit for the dark days surrounding the new moon, since moonless nights bring out the strongest glow.
Arrange a night visit with a local guide. Bring insect repellent for the wait, a dry change of clothes and a waterproof pouch for your phone, because photos rarely capture the glow. It appeals to inquisitive grown-ups and bigger kids, but overcast skies or a strong moon can mute the display, so treat it as a possibility, not a guarantee.
Beaches of the wildlife refuge
A wildlife refuge now covers what used to be a U.S. Navy range, and because of that the beaches have stayed long and undeveloped, without any hotel rows. Sun Bay is the easy one, with a long curve of sand, shade from trees and room to spread out. Inside the refuge you will find Red Beach and Blue Beach, calmer and more untamed, with transparent water and outlooks across the ocean.
Head out early, while the sand is cool and the light is gentle, and pack snacks and water, because services may be scarce. You will see wild horses wandering the roads and the beaches, and the best way to appreciate them is to keep a respectful distance. A picnic, a mask and a good book are really all you need.
Esperanza and Isabel Segunda
On the north coast lies Isabel Segunda, the ferry town, an easy base that offers a plaza, a little fort, and stores for daily needs. The south coast village of Esperanza is a relaxed waterfront spot with guesthouses and open-air restaurants, and that is where most visitors pass their evenings.
At the water’s edge in Esperanza, watch the sun go down while you order alcapurrias (fritters of green banana and meat), mofongo (mashed plantain with garlic) and fresh fish. A Christmas parranda may come along, and in the dry December air the village feels lively without feeling crowded. Rainy-day backup is simple: browse the small galleries and craft shops, linger over a long lunch, or wait for the clouds to move on, since showers rarely last.
A two-day itinerary for Vieques in December
Day 1 begins after your ferry or flight arrives, when you can drop your bags in Esperanza. Spend the afternoon at Sun Bay, where trees give shade and the water is usually kinder on the Caribbean side. Daylight runs about eleven hours, so keep an eye on the clock, because the sun sets early.
Return to Esperanza for a sunset drink on the malecon, then dinner at an open-air restaurant with fish, mofongo and a coquito for dessert. If the night is moonless, a Mosquito Bay tour by kayak or electric boat is the evening’s highlight. If rain sets in, shift to a long dinner and an early night.
While the sand is almost bare and the light is gentle, Day 2 begins early at Blue Beach and Red Beach, in the refuge. Bring snorkel gear and swim when the water looks calm, and keep an eye out for the wild horses along the road.
At midday, drive to Isabel Segunda for lunch, a walk around the plaza and a look at the fort before the afternoon ferry or flight. If a downpour comes, wait it out in a cafe, since December showers usually pass quickly.
Is Vieques busy in December?
Vieques is busier in the holiday weeks and calmer in the first part of the month.
Early December is relatively quiet, with open tables and easier choices of guesthouses and rental cars. The week of Christmas and the days around New Year’s fill up as mainland visitors and Puerto Rican families arrive for the break. Book early for those busy weeks since rooms, cars and the best restaurant tables disappear first, and wait a bit longer for the quiet ones.
The island is small, with a limited number of rooms and vehicles, so even a modest rush can be felt. Beaches in the refuge remain spacious, though Sun Bay can be livelier on weekends and holidays. Mosquito Bay tours are popular on moonless nights, so reserve those early too.
The public ferry leaves from Ceiba, and small planes also serve Vieques. Some small shops may close for the holidays, particularly around December 25 and January 1.
What to pack for Vieques in December
Pack light, sunny clothing, with a layer for breezy evenings and a plan for passing showers.
- Swimsuits and a rash guard, for long days in the water and strong sun.
- Pack sunscreen and a hat, because that sun stays strong despite the breeze.
- A light rain jacket, for quick showers.
- Snorkel mask, for Red Beach and Blue Beach on calm days.
- Insect repellent, for the wait at Mosquito Bay and evenings outside.
- Sandals or water shoes work well for sandy strolls and rocky spots.
Good to know before you go
December falls outside the official Atlantic hurricane season, which runs from June 1 to November 30, though it is wise to follow local alerts when you travel. Getting to Vieques means choosing between a small plane and the public ferry from Ceiba, so it really rewards you to plan ahead and reserve early, especially over the holiday weeks.
Some shops and restaurants may close or shorten hours around Christmas and New Year.
Vieques in December vs November and January
Moving the trip to November brings warmer, a little wetter conditions, with the sea at its balmiest and the autumn rains still lingering. The island is quieter, but November still falls within the Atlantic hurricane season. The holiday lights and parrandas have not yet started in earnest.
January is drier still, with a slightly cooler sea and more mainland visitors in the first week. January 6 brings Three Kings Day, which wraps up Christmas on Vieques, and a calm winter pace returns to the island once that celebration ends. Swells can run bigger on the north coast, though the south side stays the gentler choice. Choose November for warm water and fewer people, December for the holiday mood and drier days, and January for the driest conditions and the end of the festive season.
Is December a good time to visit Vieques?
December is an excellent month for anyone seeking balmy seas, sunshine in the dry season and a cheerful island atmosphere minus the throngs.
Beach lovers, snorkelers, couples and families on school break will all find plenty to enjoy. Travelers who want empty, guaranteed-calm seas or a bustling nightlife scene may prefer another month. On arrival, settle into Esperanza, check the moon for a Mosquito Bay night and book that tour first, since it is the one thing that fills up. What stays with you from December here is the pairing of wild horses at dusk, a parranda drifting down the malecon and a kayak paddle that sets the dark water glowing blue.
