Utah can provide year round soaring from the five primary sites with secondary locations providing safari trips and possible future primary bases.

January and February is primarily flown from Logan and Morgan with wave and ridge. The wave and ridge season runs from September through May most years.

Thermal season starts in the south in early March from Parowon and moves north to the Wasatch front from Nephi to Logan in late March to early April.. Spring flying is mostly valley thermal flying. Late May brings the big mountain flying that is best in the south and moving north with the summer. Parowon is good in June, but can be trickier in July and August as the monsoon season brings moisture up from the south. Nephi peaks in early July, but has excellent soaring through September as long as you are aware of the potential for storms from the south. Logan peaks in July and August as the monsoon usually feeds just enough moisture north to provide cloud streets starting in Nevada and running northeast across Utah through Wyoming and into Montana.

Southern Utah from Hurricane to Nephi provide great big Sky thermal soaring with cloudbase from 17k to 20k. Logan provides great mountain soaring with hundreds of miles of high ridges and great alpine thermals. Cloudbases tend to be 15k to 18k.

Fall brings the westerly winds that support the raptor migration and great ridge soaring from mid-September through October.

Nephi and Logan are visitor friendly and provide great soaring all summer.. Checking for tows ahead of time is recommended.

Awesome, thank you for such a detailed answer.
