James Island 10-day forecast, out to 14 days
where the models agree, and where they splitJames Island is a small town of about 6,000 people in South Carolina (SC), sitting at 32.7°N in a subtropical climate zone. NWS, American, European each forecast James Island with their own physics, so we line all three up and flag where they disagree. Nearby towns include Charleston, Mount Pleasant, North Charleston.
We grade every model against the weather that actually happened, so you can see which forecast model is most accurate in United States before you trust any single number.

Source: NASA POWER daily data from the MERRA-2 reanalysis, 1995-2024. Each value describes a grid square of about 50 km around James Island, not a weather station, and a square that takes in sea or a large lake runs milder than the city itself. That is why this section shows change against the square's own 30-year average rather than counts you could compare with a local station. Rain and snow are left out because their long-term record in this dataset is not consistent over time. "Within the normal year-to-year swing" means the change is smaller than the usual differences between single years.
Which forecast is most accurate in the US?
CheckWeather Score, graded against the weather that actually happened
The CheckWeather Score blends temperature, wind and rain accuracy, each measured against ERA5 (the recorded weather) over the last 30 days across 1999 cities. Lower error means a higher score. See which forecast model is most accurate in United States, how we measure forecast accuracy, or which model each weather app uses.
