In March, mornings on Ambergris Caye begin with wooden boats knocking against the docks and light turning the shallow water turquoise before breakfast is over. Inland, the Cayo hills carry on with their river towns and jungle trails, and in the south the waters off Placencia wait for the whale sharks that gather later in the spring. Belize in March is a month for the reef, the rainforest and a sea that is warming week by week.

What is the weather like in Belize in March?
March is hot and fairly dry, with warm nights and a Caribbean that keeps warming along the whole coast, from Corozal in the north down to Placencia in the south. Rain does fall, but only on a few days, and it is a lighter month than February in that respect.
| Month | Belize City average high (°F) | Belize City average low (°F) | Belize City rain days | Sea at San Pedro (°F) | Sea at Placencia (°F) | Sea at Corozal (°F) |
|---|---|---|---|---|---|---|
| February | 84.9 | 70.0 | 5.6 | 80.9 | 80.7 | 80.5 |
| March | 86.4 | 71.7 | 3.9 | 81.6 | 83.7 | 83.6 |
| April | 88.6 | 74.8 | 3.3 | 82.6 | 84.3 | 84.7 |
In Belize City, March afternoons climb into the mid-80s and the nights stay in the low 70s, which means you will want a fan or air conditioning to sleep comfortably but will not need a layer after dark. The month brings only a handful of rainy days, noticeably fewer than February, and the total rainfall is well under half of what February delivers.
The sea tells the clearer story of the month. Around San Pedro it is in the low 80s, while off Placencia and Corozal it has already moved into the warm 80s, a clear step up from February on both coasts. Days are a little longer than in the winter months, about twelve hours of daylight in the middle of March, which leaves a full evening for dinner on a dock or a late walk in town.
Where to go in Belize in March
Belize has no Pacific coast, so the choice in March is between the Caribbean side with its reef and cayes, the south coast around Placencia, and the forested hills of the Cayo District. Each gives the month a different face, and the Caribbean sea is the thread that ties the coastal ones together.
Ambergris Caye and the barrier reef
San Pedro Town sits on Ambergris Caye, an island where most of the land is set aside as national park or wildlife preserve. That shapes the place: the town stays compact, and the attention turns to the water. Just offshore runs the Belize Barrier Reef, the longest in the western hemisphere, which also takes in Lighthouse Reef, Glover’s Reef and the Turneffe Islands.
March suits travelers who want to spend their days around boats, reef and beach bars, and who like a sea that is already pleasantly warm. The Atlantic hurricane season does not begin until June, so the month falls outside the official season. Sargassum, the brown algae that sometimes washes ashore on Caribbean beaches, can reach any Caribbean coast, so a beach stretch may look different from one day to the next.
Placencia and the south coast
Placencia is a village at the end of a long peninsula, with sandy streets, small restaurants and local art galleries. The activities that define it are kayaking, snorkeling, diving and saltwater fly fishing, and in March the sea has reached the warm range that makes time on the water a pleasure.
Offshore lies the Gladden Spit and Silk Cayes Marine Reserve, set up to protect a spawning aggregation site and the whale sharks that gather there. The whale shark watching around Placencia is tied to the full moons between April and July, so March is the month before the season, a time to settle in rather than to count on the sharks.
The Cayo highlands around San Ignacio
San Ignacio is the town that anchors the Cayo District, a green stretch of river valleys, jungle lodges and Maya sites. It is a different Belize from the coast: no sea, but waterfalls, caves and nature reserves such as Chaa Creek and the Mountain Pine Ridge Forest Reserve. The town also has a regional hospital, which is worth knowing if you plan to spend days on trails.
March suits anyone who wants forest and ruins in the same trip as the reef. A good pattern is to base yourself in the highlands for a few nights, then head to the coast to finish on the water.
Corozal and the northern coast
Corozal Town sits on the northern coast, a quieter corner of the Caribbean side where the sea has reached the warm 80s by March. It rounds out a trip for travelers working their way along the coast, with a bayside setting that feels far from the cayes.
What to do in Belize in March
National Heroes and Benefactors Day
The national date of the month falls on March 9, National Heroes and Benefactors Day. It was originally designated Baron Bliss Day, in honor of a wealthy Englishman who left his fortune to the former British Honduras. The name has widened since, and the day now honors a broader roll of national figures and benefactors.
If your dates overlap, expect a national holiday atmosphere in the towns, which can mean different rhythms in shops and offices. Easter and Holy Week move each year, so in some years they reach into late March and in others they land in April.
Reef days: snorkeling, diving and fishing
March is a month for getting on the water. From Placencia the activities listed are kayaking, snorkeling, diving, saltwater fly fishing and light tackle fishing, and from Ambergris Caye the barrier reef is the draw. Hol Chan and Shark Ray Alley are among the reef names around San Pedro, and farther out are the atolls of Lighthouse Reef, Glover’s Reef and Turneffe.
The Great Blue Hole is another name travelers bring to Belize. Between outings, the island towns offer the slower pleasures: a plate of fresh seafood, a rum punch at a beach bar, an evening on a dock watching the light fade.
Whale sharks and the weeks before the season
The whale shark season at Gladden Spit belongs to the full moons between April and July, which puts March just ahead of it. The spawning aggregation there draws one of the largest predictable whale shark congregations in Belize, and it is an important source of tourism for Placencia and other coastal communities.
In Belize it is illegal to take or kill whale sharks or nurse sharks. If whale sharks are the reason for your trip, April is the first month to plan around, and March makes a fine moment to scout the coast.
Waterfalls, caves and ruins in the Cayo District
A day trip into the Mountain Pine Ridge Forest Reserve lets visitors go on several hikes and visit waterfalls, caves and Maya ruins. Chaa Creek Nature Reserve, near San Ignacio, is the other name adventure travelers look for. In the wider Cayo District, the Maya sites of Cahal Pech, Xunantunich and Caracol are the names that fill many itineraries, and the cave known as ATM (Actun Tunichil Muknal) is another.
With few rainy days on the calendar in March, the highlands make an appealing counterpart to a stretch on the reef. Hiking in the forest and the sea are different trips, and you can easily fit both into one visit.
Is Belize busy in March?
March is an active month in Belize, shaped by the mix of reef trips, highland excursions and the approach of the spring whale shark season. Because the weather is warm and rain days are few, the month suits travelers who want to be outside from morning to night.
Where the crowds gather depends on what you are chasing. Ambergris Caye and San Pedro Town are the reef base for many travelers, while Placencia is the south coast base and San Ignacio anchors the highlands. The island of Ambergris is mostly reserved as park or preserve, which gives it a built-up town on one side and protected land on the other.
The calendar adds a few moments. National Heroes and Benefactors Day arrives on March 9, and Holy Week and Easter move from year to year, falling in March in some years and April in others. U.S. spring break and holiday timing can shape when Americans travel, so the exact dates you choose matter more than the month alone.
A quieter rhythm tends to belong to the places that are less about a single attraction. Corozal Town on the northern coast, the village life of Placencia and the river valleys around San Ignacio each have their own pace. Daylight lasts about twelve hours, which gives long evenings for dinner and an early start for the next excursion.
What to pack for Belize in March
Pack for heat and water on the coast, and for trails and forest in the Cayo District. The cayes call for swimwear and light clothes, while the highlands add sturdy shoes for hikes, caves and waterfall paths. Rain falls on a few days only, so a light rain jacket is enough.
- Lightweight, breathable clothes for hot days and warm nights.
- Swimwear and a rash guard or sun shirt for days on the reef.
- Reef-friendly sunscreen, a hat and sunglasses for the strong tropical sun.
- Closed shoes with grip for trails, waterfalls and cave outings in the Cayo District.
- A compact rain jacket for the few showery days.
- Insect repellent for the forest and the evenings by the water.
Good to know before you go
The U.S. State Department rates Belize Level 2, “Exercise increased caution”, because of crime, and says the south side of Belize City has historically had the highest concentration of violent crime.
The Atlantic hurricane season runs from June 1 to November 30, so March falls outside the official season. Belize has no Pacific coast, so there is no second season to consider. Sargassum, a brown algae that floats in clumps and gives off a rotten egg smell when it washes ashore, is a feature of the Caribbean and can affect any beach.
For entry, U.S. citizens need a U.S. passport valid for the length of their stay, proof of an onward or return ticket and enough funds to cover the whole stay. Tourists staying less than 30 days do not need a visa, and a Visitor’s Permit Extension adds 30 days for BZ$200.00.
Is March a good time to visit Belize?
March is a good time for travelers who want warm water, hot days and few rainy ones, and it favors the coast, where the sea has just warmed past its winter range. The Placencia and Ambergris Caye areas suit reef days, and the Cayo District rewards those who prefer waterfalls, caves and Maya sites to a beach.
Compared with February, March is warmer in the air and in the sea, and it brings fewer rainy days. The sea near Placencia warms noticeably between the two months, while around San Pedro the change is gentler. April continues the climb: hotter days, still fewer rainy days and a sea that has reached its warmest of the three months at all three coastal places.
What sets March apart is its position at the turn of the season. The days are lengthening, the sea is warming and the whale shark season at Gladden Spit lies just ahead, while National Heroes and Benefactors Day on March 9 gives the month its own national moment. It is the month to be on the water at the cayes, with the forest of the Cayo District a short change of scene away.
