Weather in Manaus in July
Brazil · 20-year averages, July
Shoulder season. July sits in between. You will get good days and you will lose some. The heat itself is manageable at 29.1 °C, but 86% humidity is what you will actually feel.
July ranks 2 of 12 in Manaus. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.
This is persistent light rain rather than storms: 17 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Natural fibres and a second shirt for the day. At 86% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: 4 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 34.4 °C and the coldest night fell to 22 °C.
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 116 mm against 37 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 75 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 86% is the real story though — it is the number that decides how the day feels, not the 29.1 °C.
How July sits in the year
Temperatures hold steady either side: 28.5 °C in June, 29.1 here, 31 in August. Nothing about the timing within the month matters much. Rain is the thing that moves: August brings 5 days less of it, so pushing the dates later buys drier weather.
Daylight in July
Manaus sits close enough to the equator that daylight barely moves all year — 12 hours in July, against a range of just 0.4 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: 8.9 °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, April is the trade worth considering — 11 points weaker on weather, and materially quieter.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
July in Manaus versus nearby
If Manaus is one option among several, the nearby comparison is worth making. Belém is close enough to be a coin toss — within a degree on temperature, 6 days more rain. Cusco is a better bet in July — 11.8 °C cooler, 15 days less rain.
So: July is effectively as good as it gets here — 4 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
