Magnetic storms in Florida
Magnetic storms in Florida, United States. Current Kp index, 3-day storm forecast, list of cities and geomagnetic activity.
Cities in region7/7
An aurora visible over Florida requires Kp ≥ 9 — current activity is below that level.

Minimum Kp shown for a realistic chance of seeing an aurora. The lower the number, the more noticeable storms are in the city.

FAQ about magnetic storms in Florida
Are auroras visible in Florida?+
Almost never. Florida lies at low geomagnetic latitudes (≈ 37.3°). Visible auroras are possible only during extreme events (Kp ≥ 9) that occur once in several years.
How do magnetic storms affect residents of Florida?+
At Kp ≥ 5 weather-sensitive people may experience blood pressure swings, headaches, sleep disturbances. Effects are moderate due to low geomagnetic latitude. However, strong G3+ storms can cause noticeable discomfort even here.
What Kp is needed to see an aurora in Florida?+
By our estimate — Kp ≥ 9 (based on the regional mean of 37.3° geomagnetic latitude). The threshold is lower in the north of the region and higher in the south. For a specific city, open its page and check the «Aurora visibility threshold» section.
Where is the best place to watch auroras in Florida?+
Best conditions are at the northernmost city in our database (Tallahassee, 30.4° N). The further north, the higher the geomagnetic latitude and the more frequent the auroras. Also important: clear sky, no city light pollution, and observation around local midnight.
What is the nearest magnetic observatory?+
The nearest observatory is Lovozero (Murmansk), at 8156 km from the centre of Florida. It belongs to the INTERMAGNET network and records the geomagnetic field in real time.
About magnetic storms: Florida
Magnetic storms in Florida (United States) today: planetary Kp = 2.7 (quiet). The database holds 7 cities in the region with live geomagnetic data and forecasts.
Pick a city from the list to see detailed information: local time, geomagnetic latitude, distance to the nearest magnetic observatory, 3-day Kp chart with forecast and aurora visibility chance. All cities in Florida use the same planetary Kp, but the local impact is computed individually per coordinates.
How a magnetic storm may manifest in Florida: at Kp ≥ 5, weather-sensitive people can have headaches, blood-pressure swings, sleep disruption. At Kp ≥ 7, GPS navigation and shortwave radio may glitch. At Kp ≥ 8 — power-grid issues. Data from NOAA SWPC, updated every 10 minutes.
Inside Florida, geomagnetic latitude varies from 35.0° to 39.6°, with a mean of 37.3°. The northernmost city, Tallahassee, gets aurora visibility opportunities first when Kp climbs; the 4.6° south-to-north spread is enough to put neighbouring cities into very different storm-response groups.
The nearest magnetic observatory tracking conditions over Florida is Lovozero (Murmansk). Combined with the planetary Kp index from NOAA SWPC, this station gives the closest reference point for how the local magnetic field behaves during storms in this part of United States.
