First 30-degree temperatures of 2025 recorded in the Maritimes

A ridge of very warm air that built out of the southern United States sent temperatures soaring on Wednesday in parts of the Maritimes.

A number of locations in northern New Brunswick had their first 30-degree temperatures of 2025. At Environment Canada monitored weather stations, 30 degrees was reach in Edmundston, Bathurst, and Miramichi. All those sites are also setting new daily high temperature records for a May 14.

Viewers – such as Marjorie Ferguson from Flatlands, N.B. – sent in personal weather station measurements of 30 degrees. Thank you to those who take time to e-mail a report or observation of weather in their area.

Many other high temperatures in New Brunswick reached the mid-to-high 20s on Wednesday. High temperatures in Nova Scotia and Prince Edward Island climbed into the high teens and low 20s, but remaining more moderate on parts of the coast.

The ridge is squarely over the region on Thursday. A very warm to hot day should be expected region wide, except for the Bay of Fundy coastline in New Brunswick and the Atlantic coastline of Nova Scotia. For those coastal areas a southwest wind is expected to be more onshore and will moderate the temperatures.

Expect widespread high temperatures in the low-to-mid 20s on Thursday. Some reaching the high 20s, with the odd community in northern New Brunswick nearing 30. It is possible we could see further new daily high temperature records set.

The building heat will come with a risk of thunderstorms in northern New Brunswick Thursday. The period of risk extending from the afternoon through the evening. Watch for showers with a chance of developing into small thunderstorms beginning between 2 and 4 PM. By 9 PM any thunderstorms that developed will likely be weakening and dissipating back into showers.

Temperatures in the region are forecast to cool Friday and the weekend.
