How to Say Good Morning in Portuguese
Starting the day with a cheerful Bom dia is essential Portuguese — and it reveals the language’s gender-agreement system that runs through all its greetings.
The Phrase
Bom dia — pronounced bohn DEE-ah
The bom has a nasal “om” sound (the ‘m’ nasalizes the vowel). In Brazil, dia often softens toward “JEE-ah.”
Copy the Phrase
The Portuguese phrase for “good morning” is Bom dia (bohn DEE-ah).
Why “Bom” Not “Boa”?
Portuguese adjectives agree with noun gender:
| Greeting | Noun | Gender | Adjective |
|---|---|---|---|
| Bom dia | dia (day) | Masculine | bom |
| Boa tarde | tarde (afternoon) | Feminine | boa |
| Boa noite | noite (night) | Feminine | boa |
So it’s bom dia but boa tarde / boa noite — matching each noun’s gender.
The Time-of-Day System
| Portuguese | Pronunciation | When |
|---|---|---|
| Bom dia | bohn DEE-ah | Good morning (until noon) |
| Boa tarde | BOH-ah TAR-jee | Good afternoon (noon–sunset) |
| Boa noite | BOH-ah NOY-chee | Good evening AND good night |
Note: there’s no separate “good evening” — boa noite covers both the evening greeting and the bedtime farewell.
Brazil vs. Portugal
The phrase is identical; pronunciation differs slightly:
- Brazil: softer, open vowels; dia may sound like “JEE-ah” (d→j before i)
- Portugal: more clipped; dia stays closer to “DEE-ah”
In Brazil, a cheerful “Bom dia!” is an especially common, warm morning greeting.

| Tenha um ótimo dia! | Have a great day! |
| Até logo | See you later |
| Até mais | See you / until later |

Frequently Asked Questions
How do you pronounce Bom dia?
'Bom dia' is pronounced bohn DEE-ah. 'Bom' = bohn (a nasal 'om' sound — the 'm' nasalizes the vowel rather than being fully pronounced). 'Dia' = DEE-ah, with the stress on DEE. In Brazilian Portuguese, the 'd' before 'i' can soften toward a 'j' sound ('JEE-ah'), so you may hear 'bohn JEE-ah.' Both are correct for their regions.
Why is it 'Bom dia' and not 'Boa dia'?
Gender agreement. 'Dia' (day) is a MASCULINE noun in Portuguese, so it takes the masculine 'bom.' In contrast, 'tarde' (afternoon) and 'noite' (night) are FEMININE, so they take 'boa': 'boa tarde,' 'boa noite.' So it's 'bom dia' but 'boa tarde/boa noite' — matching the gender of each time-of-day noun.
What are all the Portuguese time-of-day greetings?
'Bom dia' (bohn DEE-ah) = good morning, until noon. 'Boa tarde' (BOH-ah TAR-jee) = good afternoon, noon to sunset/evening. 'Boa noite' (BOH-ah NOY-chee) = good evening AND good night, after dark — used both when arriving in the evening and as a bedtime farewell. There's no separate 'good evening' — 'boa noite' covers it.
Is Bom dia the same in Brazil and Portugal?
Yes, the phrase is identical, with slight pronunciation differences. Brazil: softer, more open vowels, and 'dia' may sound like 'JEE-ah' (the d→j softening before i). Portugal: more clipped, and 'dia' stays closer to 'DEE-ah.' Both are warm and used the same way. In Brazil, 'Bom dia!' is an especially cheerful, common morning greeting.
How do you wish someone a good day in Portuguese?
'Tenha um bom dia!' (TEN-yah oon bohn DEE-ah) = Have a good day! (the most common). 'Tenha um ótimo dia' = have a great day. 'Bom dia' on its own can also serve as a brief well-wish. When parting, 'Tenha um bom dia' (have a good day) or 'Até logo' (see you later) are friendly send-offs.
