Frequently Asked Questions
How are Heat Index and Wind Chill calculated in this planner?
When temperatures reach 80 °F (26.7 °C) or above, we apply the U.S. National Weather Service Rothfusz Heat Index regression. At or below 10 °C (50 °F) with winds above 4.8 km/h, we apply the North American/UK Wind Chill formula.
Why is optimal marathon running temperature cooler than cycling or weddings?
Continuous running generates high metabolic heat with lower airflow than cycling, making 7–15 °C (45–59 °F) ideal for endurance pace, whereas outdoor wedding guests stay comfortable around 18–26 °C (65–79 °F).
What wind speed triggers caution for outdoor weddings or road cycling?
Sustained winds above 24 km/h (15 mph) disrupt floral arches, microphones, and hair styling at outdoor ceremonies, while winds above 34 km/h (21 mph) create tiring crosswind gusts for road cyclists.
