Welcome to your weekly bug bite forecast for New Brunswick! For the week of June 29, 2026, we’re seeing a moderate overall risk for pesky bites across the province. With a mix of sunshine and scattered showers, many of our buzzing friends will be out and about, especially near damp areas.
Up in Northwest New Brunswick, including areas around Edmundston and Grand Falls, expect a few warmer, humid days interspersed with some rain. This creates ideal conditions for mosquitoes and deer flies to be quite active, particularly in wooded areas and near water.
Moving over to Northeast New Brunswick, from Bathurst to Miramichi, the forecast looks a bit drier with sunny spells. While black flies might be tapering off, watch out for persistent mosquitoes and the start of horse fly season, especially near marshy coastlines.
Down in Southwest New Brunswick, around Fredericton and St. Stephen, we’re anticipating some lovely warm weather, but also a chance of evening showers. Mosquitoes will be a primary concern during dusk and dawn, and ticks remain a year-round presence in grassy and wooded spots.
Finally, in Southeast New Brunswick, covering Moncton and the Fundy Coast, expect milder temperatures with occasional humidity. Mosquitoes will certainly be out in force after any rainfall, so be prepared for those backyard barbecues. Don’t forget that Just Bite Me natural bug bite relief is readily available at retailers across New Brunswick to soothe those inevitable bites!
