Frequently Asked Questions
How accurate is this weather data?▾
Weather data from Open-Meteo achieves approximately ±2°F accuracy for temperature within the first 24 hours. Accuracy decreases with forecast range — 1-3 day forecasts are quite reliable, while 5-7 day forecasts are directionally accurate but less precise. Open-Meteo uses multiple global weather models and selects the best one for each location.
Why are temperatures shown in Fahrenheit?▾
This site is designed primarily for a US audience, so temperatures are shown in Fahrenheit (°F), the standard unit used in the United States. To convert: °C = (°F - 32) × 5/9. For example, 77°F = 25°C, 32°F = 0°C (freezing), 98.6°F = 37°C (body temperature).
What is the climate like in South Charleston?▾
South Charleston is located in Ohio in the central United States. The current conditions shown reflect real-time weather. For historical climate normals (average temperatures by month), the NOAA Climate Data Online tool provides 30-year climate averages for most US cities.
How often is weather data updated?▾
Current conditions are refreshed every hour. The 7-day forecast uses Open-Meteo's latest model run, which is updated every 6 hours with new data from global weather observations including weather balloons, satellites, and ground stations.
