Observations
1. When the jet stream comes vertically down the state of Utah, Toquerville will always get high winds out of the north.
2. If a barometric low is situated to the east of Toquerville (eastern Utah to western Colorado) we will almost always receive high "canyon winds" from the north or northeast.
3. If a cold front moves through, Toquerville will always receive high winds for at least a day or two.
4. High winds usually last two to three days.
5. There are very few days of the year we receive no wind (two days in 2009)
6. We almost always have a wind over 10 mph, if even only for a matter of minutes, often early in the morning hours, or frequently in the mid-afternoon. Unless a cold front is moving through, or the jet stream is overhead, these winds only last a short time.
7. Toquerville may experience high temperatures over 100 degrees, but unlike most other southwest areas, the high is not reached until early afternoon. And, unlike most other southwest areas, Toquerville begins to cool off between 2-4 pm; thus giving Toquerville only short periods of high temperatures during summer months.
8. The Toquerville summer evenings are not typical of southwest desert areas because Toquerville evenings typically are cool and pleasant. Toquerville only had 37 days with night time lows above 70 degrees, and no night time lows above 80 degrees.
9. St George receives far more wind from the south than does Toquerville, and Toquerville receives far more wind from the north than does St George, though only 19 miles apart.
10. The length of the day (sunlight hours) is affected more by the sunset, than by the sunrise. Over the course of the year, the sunset time changes more than does the sunrise.
