Weather in Belém in July

A hard month. July asks something of you. Go in knowing what. You should expect rain on 23 days of the month, which is more days wet than dry.

Belém barely has seasons. July scores 49 out of 100 against a best of 49 in February — a gap small enough that the month you choose matters far less here than the week you choose.

Rain on 23 of the month's 31 days, 3 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 88% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 31.9 °C and the coldest night fell to 22 °C, and the wettest single day dropped 37 mm — roughly 31% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 213 mm against 48 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 119 mm average is a reasonable planning figure, not a promise.

Wind is light at 2.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 88% is the real story though — it is the number that decides how the day feels, not the 29 °C.

How July sits in the year

Temperatures hold steady either side: 28.7 °C in June, 29 here, 31 in August. Nothing about the timing within the month matters much.

Daylight in July

Belém sits close enough to the equator that daylight barely moves all year — 12 hours in July, against a range of just 0.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 9.7 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, November is the trade worth considering — 3 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Belém versus nearby

If Belém is one option among several, the nearby comparison is worth making. Fortaleza is a better bet in July — within a degree on temperature, 14 days less rain. Manaus is close enough to be a coin toss — within a degree on temperature, 6 days less rain.

So: July is effectively as good as it gets here — 0 points behind February, which is inside the margin where the weather stops being the deciding factor and price starts being it.
