Where the readings come from
The Stations
Five Environment and Climate Change Canada stations and three BC Wildfire Service stations. Click a station on the map or its card to show it on the charts.
How complete is each record?
Data Available
One strip per station and measurement, month by month from January 2020 to today. The percentage is the share of hours with a reading, from each record's first reading to its newest.

About the data
Sources. The Nakusp, Nelson, Castlegar, Warfield and Creston readings are Environment and Climate Change Canada’s, taken from the Meteorological Service of Canada’s open data: its hourly climate archive, with the last two days or so from its real-time feed. The Akokli Creek, Smallwood and Slocan readings are the BC Wildfire Service’s, taken from its public weather data service.
Time. Every time on this page is UTC−7 (Pacific Daylight Time) all year, the same as KEI’s streamflow pages. Both agencies publish in Pacific Standard Time, one hour behind this page.
Latest readings. The newest hour each station had reported when this page was built. Precipitation over 24 hours adds up the 24 hours ending then. Pressure is rising or falling when it moved more than 0.1 kPa over the last three hours.
Precipitation. Each hourly figure is what fell in the hour ending at the time shown. Daily and monthly totals add up the hours a station reported, and the figures and the CSV say how many hours stand behind each total. A total built on fewer hours is a minimum.
Averages. A daily or monthly temperature or pressure figure is shown only when at least three quarters of its hours were reported.
Winter at the wildfire stations. Fire weather stations are set up for the fire season, and their rain gauges are not built to measure snow. Treat winter precipitation at Akokli Creek, Smallwood and Slocan with caution. None of the three measures barometric pressure.
Station maps. The close-ups and the overview map are drawn from OpenStreetMap. They show where each station is, not the station itself.
