A second day of blistering heat had Florida residents hunkering down in their air-conditioned homes and offices, with heat index values forecast to reach as high as 113 degrees.
A heat advisory was in effect for all of South Florida Wednesday and there’s not much relief in sight until early next week when rain chances increase.
“Today looks to be the hottest day of the year so far,” National Weather Service forecasters said in their Wednesday morning analysis. High pressure parked over the state with dew points near 80 means the “stage is set for a dangerously hot day.”
They said the heat index could reach 113 in parts of inland Miami-Dade and Collier counties and 110 even in coastal areas.
The high in Miami Tuesday was 94 — the warmest temperature since the late-spring heat wave of May 26-28, when it hit 98. It was 93 in Fort Lauderdale and West Palm Beach, and unofficial (actual) highs were posted in the upper 90s to 100 in parts of the interior.
The heat index topped out at 106 at Miami International Airport and Palm Beach International Airport, and 105 in Fort Lauderdale and Naples.
The high was 95 in Daytona Beach, the hottest day of the year so far. It was 94 in Orlando and 94 in Fort Pierce. where the heat index in both cities hit 109.
It was 94 in Tampa and Fort Myers, with heat index values of 103 and 108, respectively.
With light winds off the warm Atlantic and Gulf of Mexico, nighttime temperatures on the coasts haven’t had much of a chance to cool down.
The low in Naples Tuesday was 79, breaking the record for the warmest low for the date, 78 set in 2015. It was 81 in Fort Lauderdale, tying the record warm low set in 2006.
Melbourne’s low was 79, tying the record previously set in 2010, and Vero Beach tied a record with a low of 78.

TROPICS WATCH: Is this the first sign of an active August? The National Hurricane Center began monitoring a tropical wave south of the Cabo Verde Islands, which was moving west at 10-15 mph. They gave it a 20 percent chance of becoming a depression — or Tropical Storm Emily.
Forecast models are showing some development of the wave by next week, but Wednesday’s runs had it fizzling out near the Leeward Islands. The only model predicting a robust system — no real surprise here — is the Canadian (CMC).
Wind shear is currently favorable for tropical development in the East-Central Atlantic but higher around the islands until you get to the Bahamas. Sea surface temperatures are now above normal in the tropical Atlantic, Caribbean and Gulf of Mexico.
