What these numbers mean for Laval residents
The combination of a dew point in the low 60s and nearly 80 per cent humidity indicates muggy conditions for many people outdoors, even though the air temperature is lower than it was the previous day. Light northerly winds and cloud cover can keep daytime highs suppressed, which aligns with the station's observation that today will be much cooler than yesterday.
Visibility reported at 10 miles suggests there are no significant haze or fog issues at the moment, and with no rainfall recorded at the station, travel conditions should be normal on roads and highways. However, higher humidity may leave surfaces damp in the morning and could affect comfort levels for those doing physical work or extended outdoor recreation.

Using station data and limitations
These observations are drawn from a local personal weather station. While such stations offer timely, site-specific information that can be very helpful to residents, users should be aware they may differ from official government-operated stations in calibration and siting. The Weather Underground page for the station includes tools to report questionable readings for review.
For now, the immediate takeaway for Laval residents: expect cloudier and noticeably cooler conditions than the previous day, with high humidity making the air feel muggy despite milder temperatures. Keep an eye on updates from local forecasts and the station if you have outdoor plans.
