Hello, Autumn: The Fall Equinox Arrives in British Columbia

Published: September 22, 2026

Tonight, at exactly 5:04 p.m. PDT, the sun will cross the celestial equator, marking the official arrival of fall in British Columbia. The Fall Equinox is here — and with it comes shorter days, spectacular wildlife events, and some of the best aurora viewing of the year.

Whether you're a skywatcher, a nature lover, or simply someone who loves the crisp feeling of autumn air, here's everything you need to know about this beautiful seasonal shift on the West Coast.

What Is the Fall Equinox?

The word "equinox" comes from Latin, meaning "equal night." On this day, the sun sits directly above Earth's equator, meaning neither hemisphere is tilted toward or away from it. The result? Roughly equal amounts of daylight and darkness across the globe.

However, there's a subtle twist that many people don't know about. Due to atmospheric refraction — the way light bends as it passes through our atmosphere — we actually experience a little extra daylight on the equinox itself. The true "equal light" day, known as the equilux, happens a few days later. So if you're soaking up those final moments of evening light, you're not imagining it — you're experiencing a fascinating quirk of physics.

Why the Fall Equinox Matters for Skywatchers in BC

If you've ever dreamed of seeing the Northern Lights, this is your season.

Around the fall equinox, something remarkable happens in our planet's magnetic environment. Earth's magnetic field and the Sun's magnetic field align in a way that opens "cracks" in our magnetic shield — a phenomenon scientists call the Russell-McPherron effect. During this window, solar particles can penetrate more easily, causing auroras to be brighter and visible farther south than usual.

For British Columbians, this means the odds of catching the aurora borealis improve dramatically. Even if you're not in the far north, keep an eye on the sky — especially on clear, dark nights away from city lights.

A Season of Wildlife Spectacle

Fall in British Columbia is defined by one of nature's greatest events: the salmon run.

As rivers fill with spawning salmon, the region's wildlife gathers for a pre-winter feast. In the Great Bear Rainforest and along northern Vancouver Island, grizzly and black bears can be seen fishing in the rivers, fattening up for the cold months ahead. It's a powerful reminder of the interconnectedness of our ecosystems.

This is also a prime time for whale watching. Marine life becomes more active in our coastal waters during the fall, making it an excellent season for spotting orcas, humpbacks, and other marine mammals.

Embracing the Season

The arrival of fall is more than just a date on the calendar. It's a reminder of the natural cycles that connect us all — a time to reflect, give thanks for the gifts of the year, and prepare for the darker, quieter months ahead.

So tonight, take a moment to step outside. Feel the shift in the air. Watch the sunset a little earlier. And welcome the new season with open arms.

Happy Fall, British Columbia. 🍂
