Belize City in August: Weather, Warm Seas and What to Do

In August, Belize City wakes to the smell of fry jacks and coffee drifting from the cookshops, and the sky over the harbor can turn from hard blue to heavy gray within a few minutes. Rain barrels fill, the creek runs full, and the Swing Bridge opens and closes over Haulover Creek as boats come and go. It is a green, humid, unhurried month in the city that serves as the gateway to the cayes of the Belize District, and the sea around it is at its warmest.

What is the weather like in Belize City in August?

August in Belize City is hot, humid and often wet: summer at full strength, with hot afternoons and warm nights that bring little relief.

Month	Average high (°F)	Average low (°F)	Rain days	Sea (°F)
July	89.3	77.0	11.8	86.5
August	89.8	76.8	11.0	87.8
September	90.0	76.3	12.5	88.5

Highs sit near 90 degrees and the lows barely slip below the upper 70s, so a night walk along the waterfront feels as warm as the afternoon did, only softer. Rain falls on a bit more than a third of the days, which means plenty of dry stretches but also plenty of gray ones. The sea breeze moves the heavy air around, yet the humidity stays with you from sunrise to bedtime.

Plan around the water in the air. Light cotton and linen dry quickly, a compact rain jacket earns its space, and shoes that cope with wet pavement matter more than anything fancy. The days are long, with about twelve and three-quarter hours of daylight in the middle of the month, so there is room to wait out a shower and still finish the walk you started.

August also sits inside the Atlantic hurricane season, and the weeks ahead lead toward the busiest stretch. In Belize City itself, the green of the lawns and the full creek tell you the season is in full swing.

Can you swim in Belize City in August?

The sea near Belize City is as warm as it gets, around 87.8°F, so a long swim in it is a pleasure rather than a shock.

The water outings start from the city and head for the islands of the Belize District. St. George’s Caye lies eight miles east of Belize City and has a village of the same name, a place the Spaniards once called Cayo Cocina, or Kitchen Cay. Caye Chapel, English Caye and Goff’s Caye are also among the district’s offshore islands, and Turneffe Atoll belongs to the same district.

Ambergris Caye and Caye Caulker, the two island destinations the district is best known for, are part of the same Belize District as the city. Sargassum, the brown algae that floats in clumps and gives off a rotten-egg smell when it washes ashore, is a feature of Caribbean beaches in recent years.

What to do in Belize City in August

August is a month for the city’s own character: its food, its old wooden buildings, its creek and the cayes just offshore, rather than for crowds and festivals. The mood is easy. Shopkeepers talk on their porches, school uniforms disappear from the streets for the summer, and everyone keeps one eye on the sky.

The tables are where the city shines. Rice and beans with stewed chicken is the plate you see on most counters, and fry jacks with eggs or beans start the day. Johnnycakes, cassava bread, fried plantains and cool cashew fruit juice suit the heat. A cold Belikin is the local beer, and the rum punches and fresh juices are what you drink while the afternoon passes.

As September nears, the city starts getting ready for the national celebrations that open with St. George’s Caye Day. In late August you may begin to see flags, red, white and blue paint on shopfronts and rehearsals in the streets. It is a good time for people-watching if you like to see a city preparing.

The waterfront and Haulover Creek

The center of old Belize City is the Swing Bridge over Haulover Creek, a hand-operated structure that has long linked the north and south banks. Boats pass beneath it, pelicans work the water, and the waterfront buildings carry the weathered colors of a Caribbean port. In August the creek is full and the air is heavy, so a slow stroll suits the day.

The Fort Street Tourism Village stands at the mouth of the creek, on the northern bank, and is the area that welcomes visitors arriving by water. Nearby, the Fort George area has the lighthouse and the memorial to Baron Bliss, with views of the sea and of the sky changing. The Museum of Belize, in the former prison, is a place to spend an hour or two when the weather turns.

St. George’s Caye and the nearby islands

St. George’s Caye is where the story of the country’s national day began, and its quiet village still carries the memory. The island is eight miles east of Belize City, and its name appears again every September as the country celebrates. Caye Chapel and English Caye lie in the same stretch of sea, along with Goff’s Caye.

With the water this warm, the cayes are the natural place to be when the sky is clear. Further out, Turneffe Atoll and the better-known Ambergris Caye and Caye Caulker belong to the same district. If the sky turns gray, the city has plenty to occupy you indoors.

A two-day itinerary for Belize City in August

Day 1 belongs to the city on foot. Start early, while the air is as cool as it gets, with fry jacks and coffee at a cookshop, then walk to the Swing Bridge and along Haulover Creek. Keep going to the Fort George area for the lighthouse, the Baron Bliss memorial and the open sea view.

At midday, step out of the sun for a long lunch of stew chicken with rice and beans, and let the heat of the day pass. In the afternoon, visit the Museum of Belize or St. John’s Cathedral, both under a roof if the sky turns. Finish at the Fort Street Tourism Village as the light fades over the creek, with a cold Belikin on the waterfront.

Day 2 turns toward the water. The sea is at its warmest, so spend the day on the island side of the district: St. George’s Caye, eight miles east of Belize City, makes a natural goal, with its village and its place in the country’s story.

Take a long lunch of fresh fish, then enjoy the sea while the day lasts. The days are long, which leaves the evening open for dinner back in the city, with rice and beans, plantains and a rum punch. If the weather turns, the rain card is a late breakfast, the museum, and a long, slow lunch.

Is Belize City busy in August?

August in Belize City feels like a working month rather than a festival one, with the city going about its business and the pace slowed by the heat.

The Fort Street Tourism Village is where the city meets visitors who arrive by water, and the waterfront around it is the part of town most used to them. The cayes of the Belize District, Ambergris Caye and Caye Caulker above all, are the main tourist areas of the area.

What fills the days is the weather. A rainy morning sends people into cafés, cookshops and museums, and the clearing sky sends them back out to the creek and the sea. The hurricane season runs through the month and the busiest part is close, so a flexible plan serves you better than a rigid one.

For a quiet trip, the city is the right size: you can wander at your own pace, find a table at a cookshop and watch the creek. The mood becomes more festive as the national celebrations of September approach, with flags and paint in the streets.

What to pack for Belize City in August

Pack for heat, humidity and the chance of rain, with the water never far away.

Light cotton or linen clothes, because they dry fast in the humid air.
A compact rain jacket or small umbrella for the gray spells.
A wide-brimmed hat and sunscreen for the long daylight hours.
A swimsuit for the warm sea around the cayes.
Quick-drying sandals and closed shoes for wet pavement.
A small dry bag to keep a phone and camera safe from the rain.

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.

August falls inside the Atlantic hurricane season, which runs from June 1 to November 30, and activity builds from mid-August toward the peak on September 10. An average season brings 14 named storms, and Belize City has known them: Hurricane Earl came ashore about 6 miles south of the city on August 4, 2016, and Hurricane Lisa made landfall southwest of it. Keep an eye on the forecast, and keep your plans flexible.

Philip S. W. Goldson International Airport serves the city from Ladyville. Sargassum can wash onto Caribbean beaches in some seasons.

Belize City in August vs July and September

Going a month earlier, in July, brings slightly cooler seas and somewhat longer days, and the hurricane season is still in its early stretch. The air is nearly as hot, the rain is a little more frequent than in August, and the city feels much the same. It suits a traveler who wants more daylight and a bit more distance from the busiest weeks of the hurricane season.

A month later, in September, the sea is a degree warmer, the days shorter and the rain falls on more days. The month opens with the national celebrations, which begin on St. George’s Caye Day and bring flags, parades and music into the streets of the city. It is also the time when the hurricane season reaches its peak.

Choose July if you want the longest light and a calmer lead-up. Choose August for warm water and a quiet city before the celebrations. Choose September if you want the national festivities and can live with the wettest of the three months and the height of the hurricane season.

Is August a good time to visit Belize City?

Yes, for travelers who like heat, warm water and a city at its everyday pace, and who are happy to plan around the weather and keep their days flexible.

If you want dry days, a beach day without a cloud in the sky or the festive crowds of the national celebrations, another month will suit you better. August asks for patience: a gray morning, a long lunch, a walk when the sky clears.

On arrival, start with the waterfront. Walk to the Swing Bridge, look at the creek, and get a feel for the city before heading out to the cayes. What makes August in Belize City its own is the sea at its warmest, the creek running full and green, and the first flags of September appearing on the shopfronts.
