Magnetic storms in Nice

Magnetic storm in Nice today: planetary Kp = 0.0 (G0). Over the last 7 days the maximum Kp above Nice reached 5.7 (G1); storm days (G1+) this week: 3.

Nice sits at geomagnetic latitude 44.6°. The nearest magnetic observatory continuously recording the field is Lviv, 1427 km away. Population 342,669.

Magnetic storms and health of Nice residents: at Kp ≥ 5 weather-sensitive people may experience pressure swings, headaches, sleep issues. Especially pensioners and people with hypertension should watch the forecast. During a storm — hydrate more, avoid alcohol and strong coffee, avoid intense physical load.

Technical consequences for Nice at G3+: GPS, HF radio and precise positioning systems may glitch. Drivers on long routes should watch the forecast for the next 24–72 hours. Data source: NOAA Space Weather Prediction Center, refreshed every 10 minutes.

Over Nice during the last 24 hours. Kp reached a maximum of 2.7 around 02:00 local time and dipped to 1.0. The planetary trend over the past 6 hours is steady — no sharp changes near Nice right now. So far this month the planet has logged 3 days with a G1 or stronger geomagnetic storm.

Aurora visibility threshold for Nice. At a geomagnetic latitude of 44.6°, the minimum Kp giving a realistic chance of visible auroras above Nice is about Kp ≥ 8. The current equatorial Dst index is 0 nT — the magnetosphere is in a quiet phase. Dst complements Kp by showing how long and how deep a storm's main phase has been — useful context when checking whether auroras are likely tonight.

Weather and atmospheric pressure in Nice right now. Temperature +18.1°C, atmospheric pressure 763.4 mm Hg (1017.8 hPa), cloud cover 0%, humidity 52%, wind 6.6 km/h. During G1+ geomagnetic storms, swings in atmospheric pressure tend to amplify symptoms for weather-sensitive people: those with hypertension often notice blood-pressure spikes, and readings below 1000 hPa combined with Kp ≥ 5 frequently bring headaches and fatigue. That is why the Nice page shows both indicators side by side. Weather data from Open-Meteo (CC BY).

Aurora viewing window for Nice tonight. Sunset is at 19:24 local time, sunrise tomorrow at 05:33. Moon phase — first quarter with 48% disk illumination. Clear sky and low moonlight make the window favorable — with enough Kp, the aurora may be visible even from within city limits..
