The short answer
Atibaia's regional comparison shows a useful seasonal change in nights and rainfall. July's modeled average daily low is 10.5°C (51°F), while January has 246.4 millimeters of average monthly rain in this calculation. Check the actual sleeping room, damp, drainage and approach during the first stay. For Pedra Grande, use current conditions and authority advice rather than a monthly chart.

Tool
Atibaia by month
MERRA2 model grid, not a station, 1991 to 2020 normals.
Average highs range from 72°F to 82°F. Rainfall peaks at 246.4 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 Atibaia 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. The returned coordinates identify the request point rather than a measured station or exact grid boundary. Use current forecasts and local warnings for the dates you choose.1,
Test cool nights and the room you will use
July's modeled daily-low average is 10.5°C (51°F); January's is 17.9°C (64°F). Those monthly averages are not the coldest possible nights. Inspect windows, airflow, damp and bedding, and ask how the actual bedroom feels during cooler weather.1
Giglio advertises air conditioning in the suite. Run the actual equipment, ask about maintenance and read recent electricity bills. Check the work room separately from the bedroom. A feature in a rental advertisement does not establish comfort or energy use for the household.6,
Inspect the entrance and drainage
January's calculated monthly rainfall is 246.4 millimeters and August's is 31.2 millimeters. Every month in this comparison has rainfall. Inspect drains, runoff, visible water entry and the final approach, then ask the owner about past repairs and interruptions.1,
Atibaia's Civil Defense FAQ names flooding, landslides, cracks and dangerous trees among reasons to seek help, with emergency contact 199. Follow current local warnings and avoid floodwater. A long-term regional total does not assess a property's flood or slope risk.5,
Choose the day for the actual outing
Pedra Grande's state page publishes visitor hours and access restrictions. Contact the site about current conditions before traveling, especially when the weather changes. Confirm the approach and return rather than treating a scenic photograph as evidence of usable access.9,
Keep weekends, safety, utilities and remote work beside the first-stay plan. A useful trial includes an ordinary working day and the rooms where you will actually live.8,
