Lytton’s climate varies, offering either a continental or Mediterranean climate, with guaranteed warm summers. Heat balsamroot ©BFandrichwaves do occur in Lytton which has sometimes made it the hottest spot in Canada, despite being several hours north of the Canada-US border. The arid summer air combined with a relatively low elevation of 230 m (750 ft) means afternoon shade in the summer can sometimes reach temperatures 35°C (95°F), even occasionally topping 40°C (104°F)!

Lytton and nearby Lillooet share the second-highest temperature ever recorded in Canada. On July 16 and 17, 1941, the temperature reached a record 44.4°C (112°F) on both days in both communities. Lytton also holds the record for the hottest temperature ever recorded in the province during August after the temperature reached 41.8°C (107.2°F) on August 14, 2004. The coldest temperature ever recorded in Lytton was -31.7°C (-25°F) on 18 January, 1950. So while Lytton has been called "Canada's Hotspot", other communities more consistently hold high temperature records.

Luckily the low humidity helps to make the hot summer temperatures more bearable though the heat can be intense. With the skies usually a gorgeous clear blue and brilliant sunlight – combined with the heat that also radiates from the valley's slopes – forest fires are not an uncommon event here in the summer.

Offsetting these intense months are Lytton's relatively short and mild winters. December and January have average pond hockey ©BFandrichmonthly temperatures just below freezing and there is often thick cloud cover, interspersed with cloudless sunny days. Severe cold coming down from the arctic outflow usually happen once or twice during the winter season but don’t often last more than a few days. The mountains to the north mostly block extreme cold from penetrating the Fraser Canyon allowing for outside adventures to be fun and not frigid.

Much drier than areas to the south of it, Lytton averages about 430.6 mm (16.95 in) of precipitation annually. However this is definitely damper than some of the driest spots in the BC interior such as Spences Bridge, Kamloops, and Osoyoos! Still, Lytton has the driest summers in the interior of British Columbia, and one of the driest summers of in all of Canada. Most precipitation happens from September to April with the late autumn and early winter being the wettest time of the year.
