Jan. 17, 2023: Good morning, Roatan! We enjoyed a day of sunshine a fresh winds yesterday. That was the pleasant feeling of dry air that we don’t get very much in the tropics. For most of us, we didn’t get above 79 degrees (26C) despite having full sun all day, and our dewpoint (a measure of how much humidity is in the air) didn’t get above 71 (21C). Those temperatures give us a heat index (what it feels like) of 82 (28C). Compare that with a typical day in May when the temperature is 89 degrees (32C) and the dewpoint is 79 (26C). That gives us a heat index of 105 (41C). When you have dry air like we have right now, you can really tell the difference when you’re it in the shade. It feels much cooler than being in the sun. When it’s very humid, even being in the shade feels hot.
We don’t need to talk about rain this week, because it’s not going to rain, so I thought we’d talk a bit more about how it’s going to feel this week.
I’ve posted a map that shows the moisture in the air through Thursday Jan 26. Blues and browns are dry air, yellow is a little moister and red is very moist. You will notice Wednesday afternoon and Thursday we get some yellow, which means the humidity will go up those days. That will make it feel a bit hotter. But we get dryer air Friday into the weekend. That makes it feel fresher. Not until Thursday Jan 26 do we get the kind of moisture that will give us scattered showers. So for the next week we’ll have sunny skies with temperatures that are warm, but “not too hot for around here,” and breezy days with seas around 3 feet, windy nights with seas around 5 feet. Have a great Tuesday!
