Forecast coverage & methodology
Ranges use available forecast samples and temperature bounds within each day; they are not observed daily highs and lows. * marks a partial day. Rain values show the wettest available forecast period, not a daily total or probability. Near-term data is hourly; later data is usually six-hourly. Missing periods remain blank. Today includes the remaining forecast only.

Interactive field mapsSources & how this dashboard works
Forecasts: MET Norway (CC BY 4.0), model guidance rather than station observations. US warnings: National Weather Service. Air quality: EPA AirNow PM2.5 and ozone contour categories, interpolated across an area, not a measurement at your address. The higher of the two available categories is shown; coverage and timestamps are labeled. Reports older than six hours are not shown as current. UV: MET Norway / Copernicus clear-sky estimates, without cloud adjustment; the peak is the highest available sample in the next 24 hours. Missing values are never treated as zero. Earthquakes: USGS catalog; small events are not comprehensively detected worldwide and reports may change. Sun and moon: SunCalc estimates for approximate area coordinates and a level horizon; terrain and atmospheric conditions can shift visible rise/set times. Timezone is inferred from area coordinates using tz-lookup and your browser’s timezone rules. Postal lookup: Zippopotam.us / GeoNames (ODbL). Location and results stay in this open page; no ZIP code is saved.
