When the next solar eclipse is visible from California
A solar eclipse in California occurs when the Moon passes between the Sun and Earth, partially or fully blocking the Sun as seen from the state. For most Californians, partial eclipses are the most common type, with the Moon covering only a portion of the Sun. Total eclipses, where the Sun’s disk is completely obscured, are rarer and track a narrow path that may briefly cross California or pass just offshore. An annular eclipse appears as a “ring of fire” around the Moon. Timing and visibility depend on eclipse type, geographic location within California, and weather conditions on the day.
Types of solar eclipses and how they appear in California
Partial eclipses dominate in California because much of the state lies outside the narrow path of totality or annularity. During a partial eclipse, the Moon covers a fraction of the Sun, and the Sun remains visibly crescent-shaped. Total eclipses happen when the umbra, the darkest part of the Moon’s shadow, touches Earth’s surface; if the path of totality passes across California, observers within that corridor see a brief period of darkness. Annular eclipses occur when the Moon is farther from Earth and appears smaller, leaving a bright ring visible around the Moon. Hybrid eclipses shift between total and annular along the path. For California, partial eclipses are frequent and safe to watch with proper eye protection, whereas total or annular events are notable but less common.
How to interpret start, maximum, and end times for eclipses
Eclipse timing is usually reported in local time for California, either Pacific Daylight Time (PDT) or Pacific Standard Time (PST), depending on the date. Key moments include the first contact, when the Moon first touches the Sun’s disk; the maximum, when the eclipse reaches its greatest extent; and the last contact, when the Moon moves away and the Sun reappears fully. Because the Sun is not an evenly covered object, each eclipse has distinct start, peak, and end times from any given location. Clouds, horizon obstructions, and precise elevation can affect what you actually see, so checking multiple local sources and official predictions helps ensure accurate planning.
Upcoming eclipses visible from California at a glance
California will experience several eclipses in the 2020s and early 2030s, with varying degrees of coverage. The table below summarizes key attributes for recent and upcoming eclipses, focusing on type, California visibility, and approximate local timing ranges. Exact times depend on location within the state, so consult official predictions for precise numbers for your city.
| Date | Type | California visibility | Approximate local timing (start–max–end) | Notes |
|---|---|---|---|---|
| October 14, 2023 | Annular | Partial across most of CA; path of annularity near Oregon-California border | ~07:06–08:16 PDT (times vary by city) | Ring of fire visible in narrow corridor; partial eclipse widely seen |
| April 8, 2024 | Total | Partial across CA; brief totality in far northwestern corner and offshore | ~~05:28–05:35 PDT total phase near coast; partial timing varies | Totality lasted seconds to a couple of minutes in coastal NW CA |
| October 2, 2024 | Annular | Not visible from CA | — | Path of annularity over South America; no visibility in California |
| March 29, 2025 | Partial | Visible statewide | ~06:14–07:38 PDT (example times, varies by location) | Shallow partial eclipse; Moon covers a small fraction of the Sun |
| August 2, 2025 | Partial | Visible statewide | ~~morning hours PDT (exact timing TBD) | Timing and magnitude remain to be confirmed by predictions |
| January 26, 2028 | Annular | Partial across CA | ~morning PST (approximate) | Annular path passes South of CA; partial coverage likely |
| April 8, 2024 | Total | Brief partial/total in far northwestern CA and coastal waters | ||
| August 12, 2026 | Total | Partial across CA; path of totality over northern Pacific | ~morning PDT (approximate) | Central eclipse near or over the Pacific; CA sees partial |
| March 30, 2033 | Total | Total or very partial in far northwest CA | ~morning PDT (approximate) | Totality may clip far northwestern CA if the path grazes the coast |
How to find precise time of solar eclipse in California by location
Because the Moon’s shadow moves quickly, timing can shift by many minutes across California’s north–south extent. For any city, search reputable eclipse sites such as NASA’s eclipse bulletin, the USNO or time service eclipse calculator, or your national astronomical society. Enter your exact city or coordinates to get first contact, maximum eclipse, and last contact to the nearest second. Always verify that the tool lists local time (PST or PDT) rather than UTC, and check multiple sources to confirm accuracy, especially for partial phases where small differences are common.
How to safely view a solar eclipse in California
Never look directly at the Sun without proper protection except during the brief total phase of a total eclipse. Use ISO-certified eclipse glasses or handheld solar viewers that meet the ISO 12312-2 standard; inspect filters for scratches or damage before use. Alternatively, project an image of the Sun with a pinhole or telescope onto a white card, or use a camera or telescope equipped with a certified solar filter. Do not use regular sunglasses, smoked glass, or unfiltered optical devices. For partial eclipses, protect your eyes at all times; during totality, when the Sun is completely covered and the Moon’s corona is visible, you may remove filters only for the duration of totality and recommence protection immediately.
