Cloud base/cloud ceiling for VFR pilots and their cloud tops
-
Fairly new to Windy, and just subscribed to premium if that allows me to see more features?
What do people use to estimate cloud tops? I understand the difference between cloud base/ceiling and their associated octas but i'm struggling to really understand cloud tops etc.
As background I am a flight instructor, and I would like to know how to use cloud features to my benefit. Generally I like to know how low the clouds will be, and their vertical extent. What do other VFR pilots look for in cloud maps? -
The description of Cloud layers may help you:

For VFR (Visual Flight Rules) pilots, understanding cloud base, cloud ceiling, and cloud tops is essential for safe navigation. The cloud base is the altitude at which clouds begin to form above ground level (AGL), determining how low pilots can fly while maintaining VFR conditions. The cloud ceiling refers to the lowest layer of clouds covering more than half the sky (broken or overcast), which can significantly impact VFR flight by restricting visibility and requiring adherence to specific cloud clearance rules. In most controlled airspace, VFR pilots must remain at least 1,000 feet above, 500 feet below, and 2,000 feet horizontally from clouds. While cloud tops are more relevant for IFR pilots, VFR pilots may consider them when flying above a cloud layer, ensuring VFR conditions exist at cruising altitude and their destination. To maintain safe operations, pilots should always check METARs, TAFs, and PIREPs to assess cloud conditions and confirm compliance with VFR weather minimums.
