What is the lowest data that wind and rain affect the take-off of aircraft?

First of all, we should know that different aircraft types (big or small), different captains (high or low level) and different airports (good or bad blind landing navigation equipment) have different requirements for takeoff meteorological standards.

Rain has little effect on take-off, mainly visibility. The minimum standard of runway sight distance is generally 400 meters, below which you can't take off and land.

Thunder has an impact on the take-off and landing of aircraft. Lightning strike will cause damage to aircraft parts, and the aircraft that exceeds the standard cannot be released.

Wind has a great influence on aircraft, including wind speed and direction. For example, a wind speed greater than 65 knots can cause damage to an aircraft's open door. The angle between the wind direction and the runway is very important, and the crosswind will make the plane deviate from the runway. Then there is low-altitude wind shear, which is the plane killer. These airport meteorological departments will make a forecast.

One more thing, the weather at the departure and destination airports is fine, so the plane may not fly! Because there may be bad weather in the middle route. This is what travelers usually don't understand.
