What is the dew point in Upper Grand Lagoon today?

Today's dew point for Upper Grand Lagoon is shown at the top of this page in °F, alongside the relative humidity and a comfort reading. The dew point is the temperature to which air must cool to become saturated — the higher it is, the more moisture is in the air.

What's the difference between dew point and humidity?

Relative humidity is a percentage of how close the air is to saturation at the current temperature, so it swings as the temperature changes through the day. Dew point is an absolute moisture measure that doesn't move with temperature, which makes it the better gauge of how muggy the air actually feels.

What dew point is comfortable?

A rough comfort scale: below 55 °F feels dry and pleasant; 55–60 °F is comfortable; 60–65 °F starts to feel sticky; 65–70 °F is humid and uncomfortable; above 70 °F is oppressive and, in heat, dangerous. Most people notice the air turning muggy once the dew point passes about 60 °F.

Why does a high dew point feel worse?

When the dew point is high, the air already holds a lot of moisture, so sweat evaporates slowly and your body can't cool itself efficiently. That's why a 90 °F day with a 75 °F dew point feels far worse — and is more dangerous — than the same temperature with a 50 °F dew point.

What the dew point tells you in Upper Grand Lagoon

The dew point is the temperature the air would need to cool to before water vapor starts condensing — a direct measure of how much moisture is actually in the air. Unlike relative humidity, which rises and falls with the temperature through the day, the dew point stays put, which is why meteorologists treat it as the honest gauge of how the air feels.

As a rule of thumb: below 55°F the air feels dry and comfortable; in the low 60s it turns sticky; past 70°F it’s oppressive and, on a hot day, genuinely dangerous, because sweat can’t evaporate fast enough to cool you. Upper Grand Lagoon’s current reading of 73°F puts the air in the “miserable” range.
