Springtime Soaring: Navigating the Dynamic Skies of the UK

As the winter chill begins to thaw, many paragliders are eager to unpack their wings. But before you leap into the blue, let’s temper that enthusiasm with a touch of caution and a review of what spring flying in the often entails, especially in climates like the UK.

The Meteorological Mood of Spring

Spring in the UK is a season of transition and contrast. The increasing strength of the sun warms the Earth unevenly, leading to some unique atmospheric conditions that can dramatically affect paragliding:

  • Strong Solar Heating: As the sun climbs higher, its rays become more effectively heat the ground. This creates powerful thermals that can lift a paraglider swiftly and significantly.
  • Cool Air: Despite the warmer sun, the air can still be quite cool, especially at altitude. This temperature difference between the ground and the air can intensify thermal activity, making the thermals particularly strong and sharp-edged.
  • Drying Terrain: Winter’s moisture slowly dissipates or is absorbed, reducing surface drag and allowing the sun’s heat to more directly affect the ground, thus enhancing thermal generation.

These conditions result in punchy thermals surrounded by areas of rapidly sinking air. This creates a challenging environment for all pilots, particularly those who are shaking off the winter rust.

Spring Flying Safety Tips

Assess Your Readiness

Before you take to the skies, honestly evaluate your experience and how current your skills are. Spring’s robust conditions are not ideal for a casual re-entry after a winter hiatus. If it’s been a while since you last flew, consider some refresher flights in milder conditions to rebuild your muscle memory.

Observe and Learn

Watch how other pilots are handling the conditions. Notice any pitching, rolling, or yawing of their wings. This can give you a real-time sense of the air’s behaviour. If it looks challenging from the ground, it will certainly be more so in the air.

Tactical Turning

Be wary of performing 360 turns close to the hill. The narrow, vigorous spring thermals can abruptly eject you into sinking air. Maintain a substantial safety margin before committing to any maneuvers that may put you at risk of rapid altitude loss.

Active Flying Is Crucial

Once airborne, focus intently on flying your wing. Spring thermals require active piloting, especially near the ground where turbulence is common. Keep your hands on the brakes and avoid distractions such as adjusting instruments or cameras. Pilots using pod harnesses should be particularly cautious, keeping their legs prepared for potential turbulence-induced collapses.

Prepared for Landing

Landing in spring can be tricky due to the unpredictable air. Get ready well in advance and be prepared for a Parachute Landing Fall (PLF) if you encounter a sudden drop or a collapse as you approach the ground. This technique can help minimise injury during a hard landing.

Maintain Distance

Keep a safe distance from the ridge while soaring. This extra space is crucial for reacting to sudden sink or for executing a necessary turn away from terrain, ensuring you have adequate clearance from the hill.

Identifying Turbulent Conditions in Spring

  1. Rapid Thermal Development:
    • In spring, the increasing strength of the sun heats the Earth unevenly, leading to powerful thermal activity. Look for signs of rapid thermal development, such as sudden cloud formation, particularly cumulus clouds, which can grow quickly and indicate strong updrafts that may lead to turbulence.
  2. Wind Shear and Gusts:
    • Spring winds can be gusty and changeable, with significant wind shear (a sudden change in wind speed and/or direction over a short distance vertically or horizontally). This can create choppy, turbulent air, particularly noticeable during transitions from calm to gusty conditions.
  3. Surface Indicators:
    • Pay attention to the movement of trees, grass, and surface water. These can provide real-time indicators of the wind conditions at lower levels. Sudden changes in the intensity of movement can signal incoming gusts or shifts in wind direction that could lead to turbulence.
  4. Obstacle-Induced Turbulence:
    • As winds increase in spring, they interact more aggressively with natural and man-made obstacles like hills, cliffs, and buildings. These interactions can produce turbulent rotor zones on the leeward sides of these obstacles. Be especially cautious in these areas.

What to Look for in Wind Forecasts

  1. Wind Speed and Gust Factor:
    • Examine both the average wind speeds and the gust factors. In spring, gusts can be significantly higher than the average wind speed, creating conditions ripe for turbulence. A high gust factor indicates unstable air and potentially challenging flying conditions.
  2. Directional Stability:
    • Check the forecast for changes in wind direction. Frequent shifts can indicate unsettled weather and increased risk of turbulence. Steady wind directions tend to be associated with more stable conditions.
  3. Thermal Forecasts:
    • Some advanced weather services provide thermal forecasts that predict the strength and distribution of thermals. Strong, narrow thermals can be particularly turbulent, especially if they are spaced closely together, leading to complex aerial environments.
  4. Local Weather Phenomena:
    • Be aware of local weather phenomena that might influence turbulence. For instance, valley breezes, sea breezes, or specific frontal activities can all impact the conditions differently, depending on your geographic area.

Additional Tips

Use Technology: Leverage apps and tools that provide real-time wind and weather data specifically tailored for paragliders. These can offer updates that might not be available in general weather forecasts.

Consult Local Coaches: If you are feeling a little rusty, then do not take-off first. Watch someone more experienced to take the lead and watch their experience before deciding whether it is for you.

Continuously Monitor: Conditions can change quickly in spring. Continuous monitoring of the sky and weather updates during your flying day is essential to stay ahead of any adverse changes.
