What you get
Nothing here is interpolated or guessed between readings. Every number carries the time it was taken, so you can decide how much to trust it.
Official tests
12 supervised beaches, sampled by HRM
E. coli for lakes, Enterococci for the ocean, weekly from July 1 to Aug 31. This is the only signal that is a ruling; everything else is context.

somewhere quiet with kids?
Birch Cove. Shallow, warm, and tested clean this morning.
Hugo
Ask for a beach in plain words
Peaceful or busy, kids or surf, car or bus. Hugo answers from the same tested data as the map, and says so when a beach is on advisory.
HRM beach sampling for the rulings. Environment and Climate Change Canada, station Halifax Stanfield, for rain and temperature. Nova Scotia's reported blue-green algae list. Sentinel-2 L1C for the lake index.
Beach samples weekly in season. Weather daily, with a one to two day lag, plus an hourly station reading. Province list checked every 30 minutes. Satellite whenever the sky is clear, about every 10 days.
The prediction is rain only and is scored openly against the tests. The satellite index is unvalidated: backtest hit rate 3 of 28. None of this is a safety rating. The official sample is.
