Canadian Wildfire Smoke Brings Haze and Mild Heat to Philadelphia This Week — Here’s Your 7-Day Forecast

Philadelphia, PA – Hazy skies and warm temperatures are expected to linger over the Philadelphia region this week, as Canadian wildfire smoke continues drifting into the area. While the haze may filter the sun and cap temperatures slightly, conditions will remain largely dry and seasonable, making for a relatively calm start to August.

Hazy Tuesday with Near-90° Temperatures

Tuesday’s forecast calls for highs near 89°F, under partly cloudy skies and a noticeable haze from the wildfire smoke. The northerly winds helping transport the smoke southward will also keep humidity levels lower than usual, offering some comfort despite the warmth.

While the haze isn’t expected to cause major health impacts for most residents, those with respiratory issues should still limit prolonged outdoor activity, especially during the afternoon.

Midweek Brings More Clouds, Mild Showers South of City

On Wednesday, high pressure to the north will help keep Philadelphia mostly dry, but expect increasing cloud cover from a developing weather system to the south. Temperatures will dip slightly into the low 80s, and a few stray showers may appear late Wednesday into Thursday, mostly affecting areas south and east of the city.

By Thursday, expect mostly sunny skies, with highs in the low 80s and pleasant conditions continuing into the weekend.

Pleasant Weekend Ahead Before Rain Returns

The region is headed for a dry and comfortable weekend, with highs in the mid-80s and a mix of sun and clouds. While Saturday looks perfect for outdoor plans, Sunday brings a slight chance of showers, particularly later in the day.

Monday may see the return of scattered, more widespread rain, as a frontal system pushes into the region.
