The short answer
The regional comparison shows warm nights, hotter daily highs later in the year and much more calculated rainfall in March than August. That pattern helps choose what to inspect in a home. It cannot establish a lagoon's water level, the next week's weather or the safety of a particular route. Try the bedroom and work room, then plan the actual outing around current conditions.
- The chart uses regional modeled data, not a local station.
- Inspect cooling, airflow and nighttime comfort.
- Check drainage and the actual entrance.
- Confirm present park access and lagoon conditions.

Barreirinhas by month
MERRA2 model grid, not a station, 1991 to 2020 normals.
Average highs range from 87°F to 97°F. Rainfall peaks at 293.3 mm a month. NASA POWER, 1991 to 2020 daily MERRA2 grid estimates (opens in a new tab)
The chart calculates 1991 to 2020 averages from original NASA POWER daily MERRA2 estimates around the Barreirinhas city reference point. It gives equal weight to thirty year-specific monthly daily-high means, daily-low means and rainfall totals. The native regional grid is 0.5 degrees latitude by 0.625 degrees longitude.1,
These are regional modeled estimates, not local weather-station normals, an issued INMET normal, home measurements or a forecast. Returned coordinates identify the requested point rather than a measured station or exact grid boundary. Use current forecasts and local instructions for your dates.1,
Try the bedroom and work room
October's calculated average daily high is 36.3°C (97°F), with an average daily low of 23.5°C (74°F). July's average daily low is 21.9°C (71°F). Monthly averages are not extreme temperatures or a prediction for the week you arrive.1
Run any air conditioning or fans, check airflow, shade and windows, and ask about maintenance and recent electricity use. Test the work room as well as the bedroom. A furnished rental option does not establish cooling equipment or comfort in the actual unit.6,
Inspect water entry and the approach
March's calculated average monthly rainfall is 293.3 millimeters, compared with 11.2 millimeters in August. Every month in this comparison has rainfall. Inspect drains, visible water entry, storage and the last part of the journey home. Ask the owner about past problems and repairs.1,
A regional monthly total does not assess a property's flood risk, water quality or drainage. Follow current local warnings and avoid floodwater. Keep the service contacts and the actual home address available.5,
Choose the actual park day
ICMBio says the park is open to visitation throughout the year. It recommends water, repellent and sun protection and requires authorized transport and guiding providers. Ask about present lagoon conditions and access instead of inferring them from rainfall averages or photographs.11
Read weekends, safety, utilities and remote work beside the first-stay plan. A useful trial includes the rooms and ordinary hours you will actually use.8,
Questions people ask
Are these local station normals?
No. They are 1991 to 2020 averages calculated from NASA POWER daily MERRA2 regional modeled estimates around the requested Barreirinhas point.
Does October's average high establish an extreme temperature?
No. It is an average of daily highs, not an extreme or a forecast. Test the actual home and check the current forecast.
Does August's lower rainfall mean no rain?
No. Every month in the comparison has rainfall. Check current conditions and inspect the home's drainage and entrance.
Can the chart establish lagoon water levels?
No. Ask the park or actual authorized provider about present lagoon conditions and access for your date.
