Sunrise & Sunset — São Paulo
Brazil · 23.6°S latitude
São Paulo sits at 23.6°S latitude in Brazil, which means its daylight hours shift noticeably across the year — from roughly 13 hours 35 minutes in December to 10 hours 41 minutes in June. All times here are calculated for São Paulo's exact coordinates (23.6°S, 46.6°W) using solar position algorithms and displayed in Indian Standard Time (IST, UTC+5:30). This page is useful for photographers, travellers, and anyone who needs precise local solar times.
✨ Golden Hour
Golden hour occurs when the sun is between 0° and 6° above the horizon. At this angle sunlight travels through significantly more atmosphere, stripping out blue wavelengths and leaving warm amber and red tones. Shadows are long and directional — for portrait photographers this means skin tones glow naturally; for landscape photographers it reveals surface texture that disappears under overhead midday light. In São Paulo today, morning golden hour lasts 30 minutes starting at 11:01 AM IST. Evening golden hour runs from 10:00 PM to 10:31 PM IST — plan to be at your location at least 10 minutes before these windows open.
Blue hour occurs when the sun is between 0° and 6° below the horizon. The sun is not visible, but its scattered light fills the sky with cool, even blue — no harsh shadows, no blown-out highlights. For cityscape and architectural photographers this is the ideal window: building lights are on, the sky is not yet black, and the balance between artificial and natural light creates depth that neither pure night nor pure day can produce. In São Paulo, this morning's blue hour runs 23 minutes from 10:38 AM to 11:01 AM IST. The evening blue hour from 10:31 PM to 10:54 PM IST .
Solar noon at 4:46 PM IST today is the moment the sun reaches its highest point directly above São Paulo's meridian. This is 286 minutes after noon because IST is a single timezone spanning all of India — São Paulo's true solar midday drifts from the clock accordingly. At solar noon shadows are at their shortest and point almost directly south. For photographers, the window between 11:31 AM and 10:00 PM IST is the harsh overhead-light period to avoid for portraits.

Each row corresponds to a specific sun angle below or above the horizon. Nautical dawn at 10:12 AM IST is when fishermen traditionally consider it safe to navigate by horizon without instruments. Civil dawn at 10:38 AM IST marks the outer boundary of the Brahma Muhurta window — the auspicious pre-sunrise period for meditation and prayer in Hindu tradition begins approximately 1 hour 36 minutes before sunrise, placing it at 9:25 AM IST today. Astronomical dusk at 11:46 PM IST marks when the sky is dark enough for amateur astronomical observation.
