Sun Path & Solar Angles for Miami, FL
Calculated solar-noon angles and a first-pass fixed-shading worksheet for Miami, FL, using transparent solar geometry rather than an unexplained chart.
On this page
Last updated August 17, 2026 · Original calculation using latitude 25.7617° N and declinations +23.44°, 0°, and -23.44°. Formula: altitude = 90° - |latitude - declination|. Time zone: America/New_York. Verify occupied-hour positions with the NOAA Solar Calculator; values omit refraction, equation of time, terrain, obstructions, and facade azimuth.
Direct answer
Calculated solar-noon angles and a first-pass fixed-shading worksheet for Miami, FL, using transparent solar geometry rather than an unexplained chart. A key reference is latitude: 25.7617° N; check the cited source, edition, units, and applicability before using it for design, compliance, procurement, or approval. Latitude is 25.7617° N; Miami, FL. June solstice noon is 87.7°; south at solar noon. Equinox noon is 64.2°; geometric solar noon. Projection ratio = 1 / tan(solar altitude). Multiply the ratio by the vertical distance the noon shadow must cover. Use this only as a hand check before a full-year study. Read the values with the cited source, edition or observation period, units and applicability; replace illustrative inputs with current project evidence before design, procurement or approval use.

Calculated solar-noon geometry
| Date | Declination | Altitude | Projection / vertical shade distance |
|---|---|---|---|
| June solstice | +23.44° | 87.68° | 0.041 |
| Equinox | 0° | 64.24° | 0.483 |
| December solstice | -23.44° | 40.80° | 1.159 |
Projection ratio = 1 / tan(solar altitude). Multiply the ratio by the vertical distance the noon shadow must cover. Use this only as a hand check before a full-year study.
Miami, FL shading record
Record facade azimuth, window head and sill, overhang height, required shaded dates and hours, coordinates (25.7617° N), time zone (America/New_York), calculation method, surrounding obstructions, reviewer and date. Compare the full model against the three noon ratios above and retain screenshots of the critical summer and shoulder-season hours. Verify hourly positions with the NOAA Solar Calculator.

Frequently asked questions
What is the sun angle in Miami, FL at the summer solstice?
The declination-only solar-noon altitude is approximately 87.7°. This is a transparent geometry check, not a substitute for an hourly solar-position calculation.
Can this size a final overhang?
No. Final shading must test occupied hours, facade azimuth, glass geometry, local horizon, adjacent buildings, terrain, daylight and thermal performance.
