Cancun Weather in March & April (2027): Dry Season Sun, Sea, Sargassum & Spring Break

Cancun weather in March and April is the driest and sunniest of the year: March averages only about 39 mm of rain and April has the fewest rainy days, about 4. Average highs climb from 31.5 °C (89 °F) in March to 33 °C (92 °F) in April, nights stay comfortable at 21–23 °C (71–73 °F), and the sea warms from about 26.4 °C to 27 °C (80–81 °F). There is no hurricane risk, but sargassum often starts arriving in these months, and spring break plus Easter (Semana Santa, 22 March–2 April 2027 for Mexican schools) make late March one of the busiest, priciest weeks of the year.

Cancun Weather in March and April: The Numbers

Air temperatures and rainfall are the official 1991–2020 climate normals from Mexico’s National Weather Service (SMN) for the Cancún station (no. 23155). Sea temperatures are NOAA’s satellite-based OISST averages for 1991–2020 for the water off the Hotel Zone, the same sources as our year-round overview. Sunrise and sunset are calculated for Cancún, which stays on UTC−5 all year.

Sources: SMN/CONAGUA Normal Climatológica 1991–2020, station 23155 Cancún; NOAA OISST v2.1 1991–2020 monthly mean. Averages, not a forecast.

Dry does not mean rain never falls. The SMN record shows 292 mm in April 2010, including 154 mm in a single day, so a stray downpour is possible. Heat can spike too: both months have reached 39 °C (102 °F) on record days. And March holds the station’s all-time lowest reading for any month, 9.5 °C (49 °F) in 1996, after an unusually strong cold front.

March vs April: What Changes

• March is the driest month of the year by rainfall and still gets the last regular cold fronts. Expect mostly sunny days, a fresh breeze, the odd windy spell and pleasant evenings. It is also the busiest month for spring break.
• April has the fewest rainy days and lighter winds. The heat builds noticeably, with highs around 33 °C (92 °F) and warmer nights, and the sea is a little warmer. After Easter, crowds thin out and April becomes one of the better-value months of the dry season.

Sun, Heat and Wind in Spring

With so few clouds, the sun is the main thing to plan around. Sunburn is an easy way to lose a day in these months, because the breeze makes the heat feel milder than it is. Use high-SPF, biodegradable sunscreen, take shade breaks between about 11 am and 3 pm, and book excursions such as Chichén Itzá for an early start.

Cold fronts become weaker and less frequent. For the 2026–2027 season the SMN forecasts 6 fronts across Mexico in March and 6 in April (out of 56 for the season), against 8 in January, and few of the spring fronts reach Cancun with much force. A windy front can still make the north-facing beaches between Km 1 and Km 9 choppy for a day and keep boats in port, so leave a free day in your plans for Isla Mujeres or snorkeling.

Sea Temperature and Swimming

The sea is about 26.4 °C (80 °F) in March and 27 °C (81 °F) in April: warm enough for long swims, and warming week by week. On calm days the north-facing beaches (Km 1–9) are the flattest; the east-facing beaches from Km 9.5 have more waves and more frequent red or yellow flags. Our Cancun public beaches guide rates each beach for swimming, and the Hotel Zone map by kilometer shows which way your hotel faces.

Hurricanes and Sargassum in March and April

Hurricanes: none. The Atlantic hurricane season runs from 1 June to 30 November, so spring trips carry no tropical-storm risk.

Sargassum: this is the real spring wildcard. In most years, amounts in the Caribbean grow through spring and the first heavy landings on Cancun’s east-facing beaches come between March and May. In 2026 it came early and big: the University of South Florida’s satellite bulletins reported record-high sargassum in the western Caribbean for March, major beaching events on the Mexican Caribbean coast, and seaweed spread across the entire Caribbean by mid-April. Punta Nizuc, at the south end of the Hotel Zone, had heavy landings that spring. 2025 and 2026 were the two biggest sargassum years on record, so treat spring 2027 as uncertain and check USF’s monthly outlook and the state’s daily sargassum map close to your dates.

The north-facing beaches and Costa Mujeres usually fare better than the open east side, but no beach is immune. Our Cancun sargassum guide explains how to read the daily reports and which areas tend to stay cleaner.

Spring Break, Semana Santa and Prices in 2027

March and April are high season, and in 2027 the two biggest crowds overlap. Easter falls early, on 28 March, so Mexico’s Semana Santa holidays land in the middle of the US and Canadian spring break waves. Dates that move demand:

Spring break is much smaller than in its heyday. The Benito Juárez municipal government (Cancún) closed the 2026 season on 12 April reporting about 30,000 spring break visitors, with the party crowd concentrated around Punta Cancún (around Km 9) rather than across the whole Hotel Zone. If you want a quiet holiday in March, pick a resort away from that stretch; our guide to Cancun spring break resorts vs quiet escapes shows where each crowd goes. Semana Santa brings a different crowd: Mexican families, busy public beaches and full ferries, especially from Holy Thursday to Easter Sunday.

For the peak weeks, book early and expect minimum stays at some resorts. Most all-inclusive quotes already include the 21% in hotel taxes; the Cancún environmental fee (about 82 MXN per room per night, paid at check-in) and the one-time VISITAX (about 285 MXN per foreign visitor, paid only at visitax.gob.mx) come on top. See our taxes, VISITAX and tipping guide.

Events and Things to Do in Spring

• The equinox at Chichén Itzá: around the spring equinox, late-afternoon light draws a serpent-like shadow down the steps of El Castillo. It is a spectacular sight and the busiest time of year at the site, so go only if you accept the crowds.
• Cenotes and ruins: dry trails and clear skies make this a good season for Cobá, Tulum and the cenote routes; see our best cenotes near Cancun.
• Semana Santa in town: downtown churches hold Holy Week services and processions; restaurants and beaches are lively all week.
• Cancún’s anniversary: the city was founded on 20 April 1970 and marks the date with local events; in 2026 that included a free concert on the Malecón Tajamar waterfront.
• Not yet in season: whale shark swimming opens on 15 May, and sea-turtle nesting begins around May.

What to Pack for Cancun in March and April

• Light, breathable summer clothes and two swimsuits.
• High-SPF, biodegradable sunscreen, a wide-brimmed hat, sunglasses and a rash guard for long snorkel sessions.
• One light long-sleeved layer for breezy March evenings and air-conditioned restaurants; by April you will rarely need it.
• Comfortable walking shoes and a refillable water bottle for ruins in the heat.

Our Cancun all-inclusive packing list has the full checklist.

Is March or April a Good Time to Visit Cancun?

For weather, it is the best stretch of the year: dry, sunny, hot but not yet humid, with no hurricane risk. The catches are crowds and prices around spring break and Easter, and the sargassum lottery. The sweet spot is April after Easter (from about 5 April 2027): the best weather of spring, warmer water and calmer demand. Choose March if you like a fresher breeze and can avoid the 22 March–2 April peak. If you prefer cooler air and lower sargassum risk, see Cancun weather in January and February; for the start of summer, read Cancun weather in May and June. The rest of the year is in July and August, September and October and November and December, and more planning help is in our Cancun travel tips.
