Summerside, Prince Edward Island, is in for a mostly sunny and warm week ahead, with temperatures climbing into the high 20s before showers move in midweek.

According to Environment Canada, Monday will be mainly sunny with a high of 23°C and a humidex of 25. The UV index will reach 6, which is considered high.

Tuesday will be the hottest day of the week, with a high of 27°C and a humidex of 29. The UV index will climb to 8, or very high, meaning extra sun protection is needed. Residents are reminded to apply SPF 30+ broad-spectrum sunscreen every two hours, wear protective clothing, and limit time outdoors during midday hours.

A shift in the weather is expected on Wednesday, with cloudy skies and a 60 percent chance of showers. The high will drop to 23°C. Thursday will see continued showers and a high of 22°C. Overnight lows throughout the week will be comfortable, ranging from 14°C to 19°C, which is near the seasonal normal of 15°C.

A mix of sun and cloud is expected Friday through Sunday, with afternoon highs between 25°C and 26°C. Overall, it is a good week for outdoor plans across Summerside, with only the middle of the week seeing wet weather.
