Sydney has just experienced its hottest day since February, with temperatures soaring into the mid to high 30's across the city and suburbs. The city climbed to 34.7 around the middle of the day, before a temporary sea breeze from the northeast interrupted the warming trend. However, a return of gusty winds from the northwest during the afternoon pushed the temperature back up to 37.2 degrees after 4pm, making it the hottest day since we hit 41.5 on the 5th February. This maximum of 37.2 degrees was 13.5 above the November average but still short of the 41.8 degree record set in 1982. If those in the city thought the day was hot, residents in the west did it even tougher. Penrith reached a maximum of 38.7 degrees, which is 12 above average. A cooler southerly change was still only at Merimbula at 3pm, so it is unlikely to reach Sydney until close to midnight. Therefore it's going to be a sleepless night for most, with the cooling winds from the south only really taking hold through the early hours of the morning. Tuesday will be a little more comfortable for Sydney residents, with a forecast maximum of 26 for the city and around 30 degrees for western suburbs.
