The best time of year for a wedding in Rio de Janeiro
Rio's seasons run opposite to the northern calendar, and the months that work best for a wedding here are the ones you would least expect. Rainfall and sunset times, month by month.
If you read nothing else
The short answer: May, June, September, October
Those four months are dry enough for an outdoor ceremony, mild enough for a whole day in formal clothes, and outside the two weeks of the year when travelling to Rio is at its most expensive.
July and August are drier still and belong on the list if you do not mind a cooler evening and an early sunset — Rio’s winter is not cold, but it is dark by half past five. December to March is the wet season, and it also holds New Year’s Eve and Carnival, which distort every flight and hotel price in the city.
There is a commercial consequence worth knowing: those good months are the quiet half of the Brazilian wedding calendar. The season that suits an international couple best is the one with the most availability here.
The table to plan from
Month by month: rain, sunset and what it feels like
Average monthly rainfall for the city of Rio de Janeiro, and the time the sun sets on the 21st of each month, in Brasília time (UTC−3). These are climate averages over decades, not a forecast for your date — no month in Rio is guaranteed dry, and no month is a write-off.
| Month | Rain (mm) | Sunset | What to expect |
|---|---|---|---|
| January | 169 | 18:43 | Hottest and wettest. Peak of the rainy season. |
| February | 123 | 18:28 | Hot and humid. Carnival usually falls in February. |
| March | 139 | 18:04 | Still wet, still hot. Rain often arrives late afternoon. |
| April | 113 | 17:34 | The turn. Drying out, cooling down, sunset getting early. |
| May · recommended | 78 | 17:17 | Dry season begins. Comfortable for guests in formal clothes. |
| June · recommended | 60 | 17:16 | Dry and mild. Earliest sunset of the year. |
| July | 57 | 17:27 | Driest month. Coolest evenings — a wrap is a real idea. |
| August | 56 | 17:39 | Dry and bright. Windier than the months around it. |
| September · recommended | 73 | 17:49 | Warming up, still dry. A favourite for outdoor ceremonies. |
| October · recommended | 96 | 18:00 | Warm, mostly dry, long enough evenings. |
| November | 129 | 18:18 | Rain returning. Warm and increasingly humid. |
| December | 145 | 18:37 | Hot and wet, and New Year distorts the whole month. |
Rainfall: monthly averages from the long-running observation series for the city of Rio de Janeiro. Sunset: astronomical times for Rio de Janeiro on the 21st of each month, Brasília time. Both checked in September 2026.
The months to think twice about
December to March: heat, afternoon rain and peak season
Rio’s summer is genuinely hot and genuinely humid, and the rain that comes with it has a habit that matters for a wedding: it arrives as a heavy downpour in the late afternoon and clears. That is the hour an outdoor ceremony is scheduled for, which is why summer weddings here are planned around a covered space rather than around a forecast.
Add the guest problem. December and February are when Rio is fullest and most expensive, and a guest flying from abroad pays for that twice — once on the fare, once on the room. The same wedding held five weeks later costs your guests noticeably less, without changing anything you see in the photographs.
None of this makes a summer wedding a bad idea. It makes it a wedding that has to be planned with the covered space in mind from the first conversation, not as a contingency added at the end.
Carnival and New Year: the two weeks that change your guests’ budget
New Year’s Eve in Rio — Réveillon — and Carnival are the two periods when the city receives the most visitors of the year. Hotels move to minimum-stay packages, international fares climb, and rooms in the neighbourhoods your guests will want are booked far ahead.
Réveillon is fixed: the last days of December and the first of January. Carnival moves. It is tied to Easter, so it falls in February or early March depending on the year, and the disruption stretches for about a week either side. Before you fix a date in that part of the calendar, look up Carnival for your specific year — a date chosen from memory is how a couple ends up asking forty people to fly into the most expensive week of the Brazilian year.
Two calendars that do not line up
The southern hemisphere problem: our winter is your summer
The instinct of a couple in Europe or North America is to marry in June, July or August, because that is when everyone is free and the weather at home is good. In Rio those are winter months — and, happily, they are good months here. The instinct works. It just works for the opposite reason.
The part that does not work is the mental image. Guests coming from a northern summer picture a tropical beach holiday and pack for it, then discover that a June evening in Rio is pleasant rather than hot, and that a garden after dark in July genuinely calls for a jacket or a wrap. Say so on the invitation.
One more thing about time. Brazil abolished daylight saving in 2019, so Rio is UTC−3 all year. The time difference between Rio and where your guests live changes when their country changes its clocks and not when Brazil does. Write every time on the invitation, the schedule and the transport plan as a local Rio time, and say so.
Sunset decides your ceremony hour
Rio is close enough to the tropics that the days never get very long or very short, but the swing is still enough to move a wedding. Sunset runs from about a quarter past five in June to about twenty to seven in December — an hour and a half of difference between the two ends of the year.
The usual approach for an outdoor ceremony is to start 60 to 90 minutes before sunset: the vows happen in daylight, the photographs catch the low sun, and the guests arrive at the reception as the lights come on. Applied to a June wedding that means a ceremony beginning in the late afternoon; applied to December, it means the same wedding starts more than an hour later, and dinner runs later with it.
This is the single most useful reason to fix the month before anything else. The month sets the ceremony hour, the ceremony hour sets the whole running order, and the running order is what your suppliers quote against.
The honest version
What happens if it rains on the day
Além do Sonho Eventos has a covered hall with high ceilings that takes a full ceremony and a full reception. It is a room with the finish of the rest of the house, not a marquee raised in a hurry.
Most of the estate is covered in any case — the ceremony lawn is the open-air part. In practice, moving indoors changes the setting and does not change the wedding: the same running order, the same hours, the same suppliers. The estate also runs on its own backup generator, which is the thing you want on the one evening a summer storm takes the power out.
What you should settle in writing, whatever month you choose, is who makes the call and by when. Agree it with your planner and with us while the contract is being written, not on the morning itself.
Which dates are still open
Availability is the one thing a page cannot answer honestly, because it changes weekly. What is worth knowing is that the months this page recommends are the quieter half of the Brazilian wedding calendar, so a date in May, June, September or October is usually easier to get here than the equivalent Saturday in November or December.
The house recommends about a year of lead time, and a destination wedding uses it: your guests need that margin for fares, leave and, for some passports, a visa. A date is held with a formal reservation before the contract is signed.

Questions about timing
What is the best month to get married in Rio de Janeiro?
May, June, September and October. Those months sit in Rio’s dry season, the temperature is comfortable for a whole day in formal clothes, and they avoid Carnival and New Year, when flights and hotel rooms in the city are at their most expensive and hardest to book. July and August are drier still, with cooler evenings and the earliest sunsets of the year.
When is the rainy season in Rio de Janeiro?
Roughly December to March, with the peak in December and January. Rain in that season is typically a heavy late-afternoon downpour rather than all-day drizzle — which is precisely the hour an outdoor ceremony is scheduled for. The driest months are June, July and August.
What happens if it rains on the wedding day?
The ceremony moves indoors. Além do Sonho Eventos has a covered, high-ceilinged hall that takes a full ceremony and reception, not an emergency marquee, and most of the estate is covered in any case — only the ceremony lawn is open-air. The estate also has its own backup generator, which matters in a summer storm.
Why should we avoid Carnival and New Year for a wedding in Rio?
Not because of the venue, but because of your guests. Those two periods are when Rio receives the most visitors of the year: international fares peak, hotels sell minimum-stay packages, and rooms are booked far in advance. A wedding a few weeks either side of them costs your guests dramatically less to attend.
What time should the ceremony start?
Work backwards from sunset. In Rio the sun sets between about 5.15pm in June and about 6.40pm in December, so the golden hour for an outdoor ceremony moves by more than an hour across the year. Couples commonly start the ceremony 60 to 90 minutes before sunset, so vows are in daylight and the first drinks are at dusk.
Does Brazil change its clocks for daylight saving?
No. Brazil abolished daylight saving time in 2019, so Rio de Janeiro stays on Brasília time, UTC−3, all year. The consequence for an international guest list is that the difference to Europe and to North America changes when those countries change their clocks, not when Brazil does — so always write the time on the invitation as a local Rio time.
