Cozumel in November: Weather, Sea Temperature, Day of the Dead Traditions and What to Do

On the first days of November, families in San Miguel set out marigolds, candles and plates of pan de muerto on small altars, and the scent of copal drifts along the waterfront. The island exhales after the wet weeks of autumn, the sea is still bathwater warm, and the reef is waiting. Come November, Cozumel is made for divers and snorkelers, and for anyone who loves a Caribbean island that has eased back into its own rhythm.

What is the weather like in Cozumel in November?

November is warm and humid with the rain easing off, so most days are sunny enough for the beach, with a shower or two passing through now and then.

Mornings start soft and bright, and afternoons are warm enough for shorts, with a breeze off the water that takes the edge off the heat. Evenings are comfortable for dinner outside, and nights stay mild.

Rain comes in short, sometimes heavy showers rather than whole gray days, and a cold front (a norte) can occasionally bring a cloudy, breezy spell with a choppier sea on the exposed east side. The water is still warm for swimming and diving, and days are getting shorter, so the sun sets early in the evening.

What to do in Cozumel in November

The month begins with Día de Muertos, and the rest of it belongs to the water: reef dives, snorkeling and slow afternoons in beach clubs on the calmer western shore.

Día de Muertos in San Miguel

Día de Muertos runs from October 31 to November 2, and on the island it is a family affair more than a spectacle. Altars appear in homes, schools, shops and the plaza, decorated with orange cempasúchil flowers, photographs, candles, favorite foods and sugar skulls. Pan de muerto, a lightly sweet round loaf, shows up in bakeries and cafés.

The best moment is in the evening, when people walk the plaza and the streets near it, and the cemetery is visited by families who come to remember their loved ones. Visitors are best off simply watching from the sidewalks and the plaza, and keeping a respectful distance from private family moments. Come with curiosity and quiet manners and the island is generous in return.

Diving and snorkeling on the reefs

Cozumel is known for its walls and drift dives along the Palancar and Colombia reefs, and the sea in November is still very warm, so you can dive in a thin wetsuit or none. Visibility on the reef is usually generous, and you will often see turtles, eagle rays, groupers and the island’s endemic splendid toadfish if you look under ledges.

Dive boats leave from the piers around San Miguel in the morning, and the trip takes a half day for two tanks. Snorkelers can join boat outings to shallow reefs or slip in from shore at a beach club. After a norte, the sea can turn rough and some outings change or are canceled, so check the beach flags and listen to the boat crews.

Eating on the island in the cooler season

Seafood leads the table: ceviche, grilled fish, lionfish tacos and conch, plus Yucatecan classics like cochinita pibil and sopa de lima. Evenings are mild enough to eat on a terrace along the waterfront, and a cold michelada or a fresh coconut fits the afternoon heat.

Away from the cruise piers, the streets a few blocks inland have small family restaurants and taquerías where locals eat. Wander there after sunset, when the plaza fills with families, kids and vendors selling elote and marquesitas.

On days with fewer clouds, a drive around the island is a classic outing, with windswept beaches on the east side, a lighthouse-dotted coast and a stop at a roadside shack for a drink. The Maya site of San Gervasio in the island’s interior adds a quiet walk among the trees.

Is Cozumel busy in November?

It is moderately busy, with the pace picking up through the month as the high season builds toward December.

On many days, cruise ships still pull in, so midday crowds pack the waterfront and the stores by the piers, only to clear out by late afternoon. Divers and travelers from the U.S. and Canada arrive steadily, and the U.S. Thanksgiving week brings a wave of visitors who want a warm break. Mexico’s public holiday for Revolution Day, observed on the third Monday of November, gives locals a long weekend.

Restaurants and dive shops are comfortable on most days, and rooms are easier to find early in the month than around Thanksgiving. The southern beach clubs can be lively on cruise days and calmer on the others.

What to pack for Cozumel in November

Pack for warm days, a few showers and the water, with one light layer for a breezy evening after a front.

• Light, quick-drying clothes and a swimsuit or two
• A compact rain jacket for passing showers
• Reef-safe sunscreen and a hat
• Water shoes for rocky entries at some beaches
• A light sweater or long-sleeve shirt for breezy evenings

Good to know before you go

The U.S. State Department rates Quintana Roo Level 2, ‘Exercise increased caution,’ due to terrorism and crime.

November is the last month of the Atlantic hurricane season, which ends on November 30, so a late storm is still possible and the cold fronts that start to arrive can stir up the sea. In Mexico, dollars aren’t legal tender, so a restaurant or shop might accept them and might not, while pesos are the simpler way to make small purchases.

Is November a good time to visit Cozumel?

Yes, especially for divers, snorkelers and travelers who want warm water and a calmer island once the wettest weeks have passed.

Compared with October, November has far fewer rainy days and a sea that is still very warm, while December is a little cooler and drier but busier as the holiday season arrives. November sits in the pleasant middle, with the crowds still building. What makes it special is the mix of the Día de Muertos altars in the plaza at the start of the month and the reef, warm and inviting, for the rest of it.
