Since record-keeping began at the Buffalo Niagara International Airport in 1938, there have been many hot August days, and nights.
Except for 1988, however, none have started warmer than this one, National Weather Service data shows.
The average daily high temperature so far this month is 87 degrees, nearly seven degrees above average.
And, there have already been four days in the 90s, matching the average number of 90-degree days in Buffalo for an entire year.
What's more, the heat won't abate until at least early next week.
A more pleasant day is forecast Wednesday with dewpoints dropping into the upper 50s. That'll make for a much less humid day. Temperatures are expected to reach into the lower 80s though, according to the weather service forecast.
Humidity starts returning Thursday with a chance for thunderstorms and temperatures in the low 80s.
Then the heat and humidity comes back strong Friday and through the weekend, according to forecasts.
The thermometer is expected to crest into the upper 80s again, the forecast shows.
All of that should push the streak of consecutive days at or above 80 degrees in Buffalo to at least 21 through Sunday, which would vault the mark from its current place in 12th on the all-time list up to 4th, according to weather service data.
Early forecasts show a projected high temperature Monday of 78 degrees.
