In which direction should flares be fired?

Flares are designed to be used as emergency signaling devices to attract attention in a distress situation on the water. Firing flares into the wind ensures that the smoke and light produced by the flare can be carried towards the direction of potential rescuers or passing vessels. This maximizes visibility and the chance of being seen.

When flares are fired with the wind, there's a risk of the smoke and flames being blown away from the area where they may be seen, potentially leading rescuers away from your location. Firing flares horizontally or at a 45-degree angle doesn't provide the optimal angle for visibility and could also create safety hazards by directing sparks or debris in an uncontrolled manner. Thus, firing flares into the wind is the safest and most effective method for signaling distress.
