Day 2 of an exceptional stretch of extreme heat across B.C. yielded a 40-degree reading in Lytton, tying a national record for September
A late-summer heat wave in British Columbia this week has led to Lytton tying an all-time Canadian temperature record for the month.
Lytton, B.C., recorded a sizzling 40.0°C reading on Tuesday as an intense heat wave hit the West Coast, enough to tie the national heat record for the month of September.

Lytton shares the current, all-time September high with Morden, Man. (1906), and Lost River, Sask. (1940). The record is still in jeopardy of being toppled in B.C. this week, though, as the heat will continue on Wednesday.
With such heat occurring, folks may have noticed some trees have shed their leaves already, with a colour change, or will with this round of hot temperatures.
Heat wave kicks off September, tying national record
A ridge of high pressure parked over British Columbia will reinforce, prolonging the unusually high heat many communities have experienced of late. Lytton, B.C., just saw a historic streak of four consecutive 40°C days.
An exceptional September heat wave is targeting British Columbia that will rival the warmest Canadian temperature for September. That comes after a historic heat wave in late August, during which Lytton reached 40°C for four consecutive days.
