Where to Go Stargazing in March

March is a trade-off month for aurora chasers at the northern extremes, and it's worth being upfront about it. Darkness is dropping fast as the equinox approaches: Tromso is down to 5.5 hours a night, its overall score sliding from a 3 to a 2 for the first time since autumn. Tromso gains daylight faster than anywhere else on this list around the equinox, several minutes more every day through March. The usable viewing window isn't just shorter than in January, it's shrinking visibly week to week, so early March looks noticeably different from the last week of the month. Abisko (6.0 hours), Finnish Lapland (6.5) and Iceland and Fairbanks (both 6.9) aren't far ahead. Yellowknife holds up best of the group at 7.4 hours, thanks to its lower latitude, the same reason it pulled ahead back in February.

Here's the part worth knowing before you write March off, though: the spring equinox itself tends to boost geomagnetic activity. It's a well-documented seasonal pattern, sometimes called the equinox effect, where storms cluster more heavily around the March and September equinoxes than at other points in the year. So while you get fewer hours of darkness to work with this month, the odds of something happening during those hours go up. Shorter window, better odds per hour. The mechanism, called the Russell-McPherron effect, comes down to geometry: near the equinoxes, Earth's magnetic field tilts in a way that couples more efficiently with the solar wind's field, letting more energy leak into the magnetosphere and trigger storms. The aurora season guide explains the geomagnetic side of this in more depth.

The Milky Way wakes up

AlUla, Big Bend and Wadi Rum are all logging a strong 9.5 hours of darkness and a full score-3 rating this month, with Joshua Tree just behind at 9.4 and Death Valley at 9.3. Tenerife, La Palma and Merzouga round out the list a step behind, at 9.4 to 9.5 hours but a slightly lower score. This is close to the sweet spot for desert stargazing: nights are still long enough for a full session, but the worst of winter haze and storm systems has usually cleared out.

The new moon falls in mid-to-late March; check the sky facts panel above for the exact date each year. There's no major meteor shower this month to plan around, which actually makes it simpler: pick your dark-sky window off the moon calendar alone, check the forecast a few days out, and go.

Nothing in the southern hemisphere shows up as a strong pick in March, and that's expected. It's early autumn there, with nights lengthening but not yet at their winter best. There's a small signal worth watching: by April, Uluru and the Atacama Desert both start reappearing near the top of the Milky Way picks as southern-hemisphere nights lengthen into autumn. March is too early to book around that shift, but April onward is when a southern trip starts to make sense. If you're planning from the southern hemisphere, June through August remains the window to build a trip around Aoraki Mackenzie or similar southern dark-sky sites. March's real strength is squarely in the north.
