Hourly temps from the past 12 hours come from Open-Meteo's weather model analysis. Every hour, the model ingests real observations from thousands of ground stations and satellites worldwide, then produces its best estimate of what actually occurred. It's not raw station data, but it's very close — typically within 1–2°C of what a nearby station would record.

The most recent model analysis run, updated hourly.

Future weather comes from Open-Meteo's GFS/ECMWF ensemble forecast. Accuracy is highest in the next 24 hours and gradually decreases beyond 3–4 days.

Daily summaries also come from Open-Meteo model analysis — the same observation-assimilated data as the hourly strip, just aggregated to daily highs, lows, and totals.
