Weather in Manaus in April

Shoulder season. April sits in between. You will get good days and you will lose some. You should expect rain on 27 days of the month, which is more days wet than dry.

April ranks 3 of 12 in Manaus. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 27 of the month's 30 days, 9 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 89% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 3.8 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 31.1 °C and the coldest night fell to 22.1 °C, and the wettest single day dropped 78 mm — roughly 30% of the month's rain in one day.

April is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest April on record still delivered 458 mm against 127 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 262 mm average is a reasonable planning figure, not a promise.

Wind is light at 2.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 89% is the real story though — it is the number that decides how the day feels, not the 28.5 °C.

How April sits in the year

Temperatures hold steady either side: 28.7 °C in March, 28.5 here, 28.5 in May. Nothing about the timing within the month matters much.

Daylight in April

Manaus sits close enough to the equator that daylight barely moves all year — 12 hours in April, 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

Shoulder. The value months — prices ease off and you get the place closer to itself. April is the value pick for Manaus: it scores within 11 points of August without carrying August's prices.

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

April 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, 2 days more rain. Cusco is a better bet in April — 11.9 °C cooler, 20 days less rain.

So: April works, with August the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
