Forget #HeatIndex. #WetBulb Globe Temperature Is Where It’s At.

"One of the most common terms we hear during the summer when discussing the weather is Heat Index. While the Heat Index can give you an idea of how dangerous the heat can be, there is another lesser known variable that may give a complete description, known as the #WetBulbGlobeTemperature.

"The Heat Index is a measure of how hot it feels to the human body, taking into account the temperature and the relative humidity. The higher either one value is, the higher the heat index and the greater the stress exerted on the body. Heat Index utilizes the temperature measured in the shade and therefore will likely be greater in the sun, where many activities take place. For temperatures taken in the full sunlight, Heat Indices can increase as much as 15°F. Humidity plays a major effect on cooling the body. If the humidity is high, sweat on the surface of the skin does not evaporate as quickly, slowing the cooling of the body. If the humidity is low, sweat evaporates too fast, leading to dehydration. [See link for Heat Index chart]

"Wet Bulb Globe Temperature (#WBGT) is similar to the Heat Index in that it is an indicator of the stress on the body from the heat. While it is not as well-known as the Heat Index, it’s not a new term. WBGT was developed in the 1950s after heat related illnesses affected the US armed services during the 1940s. After its implementation, there was a reduction in heat related illnesses during basic training. One fundamental difference between the Heat Index and WBGT is that the latter is calculated with the temperature measured in the sun. While Heat Index only takes temperature and Relative Humidity into account, WBGT takes several variables into account.

These variables include:

- Temperature
- Humidity
- Wind Speed
- Sun Angle
- Cloud Cover
- Physical Activity"

#HeatIndex versus #WetBulb temperatures

The world needs a new way to talk about heat

by Michael J. Coren
July 25, 2023

"[The heat index] warning system is not perfect. First, it assumes you’re resting in the shade, not working in the sun. If you’re exerting yourself outdoors, the effective heat index could be 15 degrees higher. Secondly, the heat index was built on the idea of a young and healthy adult — a bad assumption for the elderly, very young and sick."

New California tool ranks extreme heat danger by neighborhood. Here's how it works | LAist

It’s going to be hot this summer. And a new tool can help you figure out the risk that the temperature can pose to your health.

The California Communities Extreme Heat Scoring System — which the state is calling CalHeatScore — can tell you the level of heat-related health risk you face and point you to cooling resources in your area.

This pilot program ranks risk from extreme heat into four categories, from mild to severe. A ranking of “severe,” for example, could correspond with a higher temperature inland, as opposed to at the beach.

We’ve reached the time when the summer heat outweighs any desire for design & aesthetic. Portland is having a second 90F/32C day so I’ve deployed my janky looking, but very effective hack to block the only west-facing window in our home.

This window is one of those window boxes, so it not even remotely insulated, double-paned, or anything that would improve its efficiency. In the winter cold pours in from this space and in the summer this unshaded window belches temperatures above 105F/40C into the kitchen. On the positive side, our cat loves this space, he lounges on some carpet we put in the bottom and yells at birds.

If you’re struggling with rising temperatures and have access to a a place that sells construction materials, you might consider buying some of these R-Tech insulation panels to block windows. These are coated with Mylar on the side I’m facing out, towards the sun. It’s impressive how well they work!

I’ve been thinking I’ll order some insulated curtains for this space, but my wife has wondered if this fix is actually more effective! We might still hang some, but I’ll keep these two panels around for extremes.

After a couple of weeks of cool, breezy conditions, the temperatures across Southeast Texas are already heating up into weather Houstonians are all too familiar with.
