NEW YORK, Aug 20 (Reuters) — New York faces an 85°F (29°C) high today with humidity levels that could push the heat index past 90°F, according to the latest clima de hoy forecasts from Univision, El Diario NY, and TN.
Thunderstorms are a real possibility this afternoon.
The National Weather Service data cited by these outlets points to unstable atmospheric conditions. The barometric pressure sits at 1012 hPa. Wind speeds are light, from the west at 5 mph.
That combination is a recipe for sudden downpours.
Clima de Hoy en Nueva York: August 17–20 Breakdown
The forecast window shows a consistent pattern of heat and moisture.

Why 85°F Feels Hotter: The Humidity Factor
85°F is not extreme. Humidity makes it dangerous.
The heat index — what the body actually feels — climbs when moisture in the air slows sweat evaporation. At 85°F with 70% humidity, conditions feel like 92°F. The reference sources note this discrepancy explicitly.
Health risks escalate quickly: heat exhaustion, dehydration, and in severe cases, heat stroke.
Hydrate before you feel thirsty. Wear light clothing. Avoid caffeine and alcohol. These are not suggestions — they are requirements for outdoor activity today.
Thunderstorm Risk: The Meteorological Mechanics
Warm air rises. Moist air condenses. Cumulonimbus clouds form.
The pressure reading of 1012 hPa from TN’s August 19 report indicates a relatively low-pressure system. Combined with daytime heating, this creates lift. The result: sudden thunderstorms with lightning and heavy downpours.
The window of maximum risk is 2 PM to 6 PM.
Safety protocol: seek indoor shelter when thunder roars. Stay away from open fields, tall trees, and metal objects. Unplug sensitive electronics. Lightning strikes can occur even when rain hasn’t started.
Planning Your Day in NYC
Morning hours offer the safest window for outdoor activity.
Early clouds may linger, but the storm threat builds through the afternoon. Schedule outdoor exercise before noon. Move indoor activities to the 12 PM–4 PM peak heat block. The afternoon storm window demands attention.

Historical Context: This August vs. Previous Years
The data suggests a pattern — not an anomaly.
August heat in New York routinely reaches 85°F. The 30-year climatological average for high temperatures this month is 83°F. What separates this week is the persistent humidity and storm generation.
This combination is consistent with broader trends observed in recent summers. More moisture in the atmosphere means more energy for storms. The numbers confirm it.
