How to check weather by ZIP, postal code or city

Start with a place, then confirm the match

1. Enter a five-digit ZIP, a full Canadian postal code such as M5V 3L9, or a city with its state or province.
2. Choose the intended locality from the matches shown.
3. Select Yesterday or another date within the recent 30-day window.
4. Confirm the result’s place, station, straight-line distance and local date.
5. Review temperature samples, wind, available rain evidence and observation gaps.

ZIP+4 entries use the base five-digit code. Canadian city references include every province and territory. Full postal codes accept either case and an optional internal space. Only codes with a verified reference point and local time zone are supported; unresolved codes ask for a city and province and are never shortened to a postal region. Military, unlocated, conflicting or distant locations may lack suitable observations.

A code or city identifies a reference point, not your address

The lookup uses a city, ZIP locality or full postal-code reference point and does not request GPS access or a street address. A successful match can try up to three reporting stations within 50 km and keeps the first one with usable observations for the selected date.

The displayed distance is straight-line distance from the selected locality reference point to the station. It is not the distance from your device, home or worksite, and the chosen station is described as nearby rather than guaranteed to be the nearest instrument.

If a station lies across a time-zone boundary, YesterSky still uses the searched place’s local day. That keeps “yesterday” tied to the place you selected instead of silently changing dates to match the airport.

Know what this recent-weather lookup can answer

YesterSky summarizes public METAR observations supplied by NOAA’s Aviation Weather Center. It can help you see what a nearby station reported for temperature, wind and available precipitation evidence on a recent date.

It does not provide a forecast, property-level measurement, certified weather record or long-term climate archive. The low and high are sampled readings rather than official daily extremes. Rain periods can overlap, and missing rain is not converted to zero. Review the full source, station and local-date methodology before relying on a close call.

For dates older than the available window or for an official record, use the appropriate national climate-data service. YesterSky deliberately stays focused on a quick, recent look back.

Ask the next practical question

Once the location is set, check whether rain was reported yesterday, whether it may have frozen last night, or whether it was windy yesterday. The complete recent weather guide combines those workflows.
