In August, the sea around the cayes has the temperature of a bath left standing in the sun, and the water taxis cut across it past mangrove islands with pelicans on every post. Inland, the Cayo hills are green and the Mopan River runs below the ridge of Xunantunich. The month brings hot days, a lush landscape and a reef that keeps its colors, for travelers who accept some rain and a place in the hurricane season.
What is the weather like in Belize in August?
August in Belize is hot, humid and green, with a sea that stays warm all along the coast and showers that can arrive on any day. In Belize City, highs sit in the upper 80s and nights barely cool off, so you will want a fan or air conditioning to sleep well. Rain totals a bit over six inches for the month there, enough to keep the lowlands lush without turning every day gray.
| 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) |
|---|---|---|---|---|---|---|
| July | 89.3 | 77.0 | 11.8 | 85.7 | 86.4 | 87.7 |
| August | 89.8 | 76.8 | 11.0 | 86.7 | 87.6 | 89.6 |
| September | 90.0 | 76.3 | 12.5 | 87.4 | 88.8 | 89.9 |
The coast is where the contrasts show most clearly, and they are contrasts in the water. The sea off Corozal Town, in the north, is the warmest of the three coastal places in the table, while the water off San Pedro on Ambergris Caye is a degree or two cooler and the water off Placencia sits between them. All three are warm enough that you stop noticing the temperature after the first minute.
Days are long, about twelve and three-quarter hours of light in the middle of the month in Belize City, which leaves room for a morning on the water and an evening on a porch. August has slightly fewer rain days than July or September in Belize City, a small difference, but it makes the month a calmer midpoint in the wet stretch of the year. For the Cayo hills, the southern villages and the northern towns, plan on the same green, humid season, with the details of the sea and the land varying from place to place.
Where to go in Belize in August
The cayes and the barrier reef
The Belize Barrier Reef is the longest in the western hemisphere, and its cayes and atolls are the reason many people come at all. Ambergris Caye, the largest of the several hundred cayes in the northern waters, is reached from Belize City by a flight of about 20 minutes. San Pedro, its town, has sandy streets, beach bars and docks where boats set out for the reef.
Farther out lie Lighthouse Reef, Glover’s Reef and the Turneffe Islands, which belong to the same reef system and draw divers and snorkelers. In August the sea there is in the mid-80s, and you may find the water as warm as the air in the evening. This is also the month to watch the sky: the Atlantic hurricane season is under way, and the cayes are exposed to the open water.
Sargassum, the brown algae that drifts across the Caribbean, can wash onto beaches in clumps and smells of rotten eggs when it does. The Belize Tourism Board describes it as a regional phenomenon that began arriving in 2011, so it is something to know about when choosing a beach stay, rather than a reason to stay away.
Placencia and the southern coast
Placencia sits on a narrow peninsula with a long sidewalk through the village and a beach on the Caribbean side. The sea off Placencia is warmer in August than off San Pedro, which suits long mornings in the water. In town, the tap water is plumbed in from an artesian well on the mainland, so you can drink it.
Evenings gather around the Barefoot Beach Bar, where happy hour runs from 6 to 7 PM and a band called Inner Vibrations plays on Sunday evenings. After the sun goes down the village is a place of small restaurants, rum punch and the sound of the surf. Rain is part of the month here, so a covered porch matters as much as a beach chair.
Corozal and the north
Corozal Town lies on the bay in the far north of the country, and its sea is the warmest of the places in the table this month. The town has a quiet waterfront and a slow pace, a counterweight to the busier cayes. It suits travelers who like a small Caribbean town without a resort feel and who are happy to spend time looking at the bay.
Corozal is also a base for the north of Belize, with Orange Walk and the Maya site of Lamanai among the places this part of the country is known for. August foliage is thick, and the landscape is at its greenest, which is the reward of traveling in the wet months. As with every coastal stop, keep an eye on the forecast during the hurricane season.
The Cayo District and Xunantunich
Inland, the Cayo District around San Ignacio is a country of rivers, hills and Maya ruins. Xunantunich stands on a ridge above the Mopan River, less than a mile from the Guatemala border, and its core holds six plazas ringed by more than 26 temples and palaces. In August the surrounding forest is deep green.
The district also holds Cahal Pech, the Mountain Pine Ridge and the cave of Actun Tunichil Muknal, the ATM cave. Lodges here, among them Chaa Creek, Blancaneaux Lodge and Ka’ana, give you a base among the trees. Without a sea, the highlands are a different kind of August: shaded, green and full of birdsong.
What to do in Belize in August
The best August plans in Belize revolve around the water and the forest, with the reef at the center. The barrier reef’s cayes, the warm sea and the Maya sites inland are all open to you this month, and the green of the wet season is its own attraction.
On and under the water
A day on the reef is the heart of the trip, whether you are staying on Ambergris Caye or out on one of the atolls. Boats take visitors out over the shallows to snorkel and dive, and the warm August sea means that time in the water does not leave you shivering. Divers talk about Lighthouse Reef, home of the Great Blue Hole, and Half Moon Caye, which are part of the reef system.
On the mainland coast, Placencia offers its own mix of sea, lagoon and mangroves. Between outings you can sit on a dock in the evening, watch the light go orange over the water and listen to the sound of boat engines slowing down. Because showers can come at any time, build your days around the water and keep a few hours free for indoor pauses.
Maya sites and the green interior
Xunantunich is the Maya site that puts August to best use. From its ridge you look down on the Mopan River and across the forest toward the Guatemala border, and you walk through plazas lined with temples and palaces. The site belongs to the Cayo District, where the season’s rain keeps the forest thick and the river full.
Caracol, Lamanai, Altun Ha and Cahal Pech are among the other Maya sites in the country, each set in its own stretch of forest or beside water. In the hills you can also look into caves and rivers, and the district’s lodges and trails make it easy to add days. Nature in August is a green, humid affair of birds, leaves and running water.
Evenings on the coast
Evenings in Belize are a slow ritual of rum punch, fresh fish and conversation. In Placencia, the Barefoot Beach Bar has its happy hour from 6 to 7 PM and live music from Inner Vibrations on Sunday evenings. In San Pedro the streets fill with the sound of music from beach bars, and the sea breeze softens the heat of the day.
Belizean cooking is a mix of Creole, Garifuna, Maya and Mennonite traditions, and a trip is a good chance to taste rice and beans with stew chicken, fry jacks at breakfast or a bowl of seafood soup. Garifuna drumming and Creole stories are part of the culture, and in towns like Hopkins and Dangriga you may find music in the evening.
Is Belize busy in August?
August is a month when Belize can feel relaxed, with the main attractions set in a green, humid landscape and the reef open to all. It falls in the summer vacation months for many American families, and the water, the long days and the warm sea give the cayes a holiday mood.
Because August sits inside the hurricane season, travel in this month is shaped as much by the forecast as by the calendar. Flights to Ambergris Caye and boats out to the atolls are the parts of a trip that depend on the weather, so it helps to keep your plans flexible and to leave a day or two of room. Inland places like San Ignacio and the Cayo lodges, set among hills and rivers, give you somewhere to be when the coast is wet.
In the towns, the rhythm is one of small restaurants, markets and docks rather than crowds. San Pedro is the busiest face of the cayes, while Placencia, Corozal Town and the Garifuna coast around Hopkins keep a smaller scale. Wherever you stay, you will share the sand with fishing boats and the occasional pelican rather than with a long line of beach chairs.
What to pack for Belize in August
Packing in Belize in August is mostly about heat and rain, with small differences by region: the cayes call for swimwear and sun protection, the Cayo hills for sturdy shoes and a rain layer, and the towns for light clothing that dries quickly.
- Light, quick-drying clothes for hot, humid days, with a second set ready when the first is damp.
- A light rain jacket or a compact umbrella for the showers that come through during the month.
- Swimwear and a rash guard or sun shirt for days on the warm sea, plus reef-safe sunscreen and a hat.
- Closed shoes with grip for Maya sites and forest paths, and sandals for the coast.
- A refillable water bottle, which you can fill from the tap in Placencia, where the water comes from an artesian well on the mainland.
- A dry bag or waterproof pouch to protect a phone and camera on boats.
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, and activity builds from mid-August toward its peak in early September, so August sits at the start of the busiest stretch. Hurricane Earl came ashore about 6 miles south of Belize City on August 4, 2016, a reminder that storms can reach the country in this month. Sargassum can also reach Caribbean shores, and the Belize Tourism Board describes the algae as floating in clumps that smell of rotten eggs when they wash up.
Is August a good time to visit Belize?
August is a good month for travelers who like warm water, green scenery and a flexible plan, and the best match is the cayes and the Cayo hills together. The sea is as warm as it gets across the year, the days are long, and the forest is at its lushest. It is less suited to anyone who wants a fixed schedule with no weather risk, since the hurricane season is under way.
Next to July, August has a slightly warmer sea at all three coastal places in the table and a touch fewer rain days in Belize City. Next to September, the sea is a little cooler, the rain days are fewer, and the peak of the hurricane season is still ahead. That makes August a middle step in the wet season, with the water warming from one month to the next.
The region to choose depends on what you want. The cayes and atolls suit people who come for the reef, Placencia suits those after a village on the Caribbean with music in the evening, and Corozal appeals to anyone who wants a quiet bay. The Cayo District, with Xunantunich above the Mopan River, is the choice for ruins, rivers and forest.
What stays with you from Belize in August is the green: the mangroves, the hills, the forest around Maya plazas and the warm sea along the longest reef in the western hemisphere, all in the middle of the wet season.
