What to Wear
When heading to Sarnia-Lambton, look at the season to decide which clothing to wear. In summer, temperatures can be above 30°C (86°F), while in winter they can drop to below -13°C (9°F), or even colder in the north.
Spring (March, April, May)
The snow that has fallen during the winter months takes longer to disappear in the north than it does in the south. Wear layers, such as long-sleeved shirts, thick pants, warm socks and sweaters. Toward the end of spring, substitute your winter jacket for a medium-weight jacket. It's wise to have a water-repellent jacket, footwear and an umbrella for Ontario's spring showers.
Summer (June, July, August)
During the summer months it is important to apply sunscreen to exposed skin to prevent sunburn. In the southern areas of Ontario, wear light pants or shorts, short-sleeved shirts, a light jacket, sandals or light shoes. Farther north, it gets much cooler at night, so bring a sweater or two.
Fall (September, October, November)
Typically, there is more rain during these months, so keep rain gear and an umbrella close. It's a good idea to wear thick pants and a medium-weight jacket to wear over sweaters or long-sleeved shirts. Footwear should cover the foot and, if possible, be water repellent.
Winter (December, January, February)
Ontario is known for its snowy winters. Temperatures can be quite low in all regions of the province, so it's important to dress in layers, starting with thermal underclothes and socks. Long-sleeved shirts under a sweater will help keep the heat in, especially when topped with a good thermal/waterproof jacket. Your best defense against the cold is to wear a warm hat - almost 90 per cent of body heat escapes through your head. Waterproof and warm boots will guard against the cold. Bundle up with a scarf and some warm mittens.
