If you're not comfortable landing in a crosswind, schedule a lesson with an experienced flight instructor. If you don't have an established relationship with a flight instructor, ask other pilots for referrals. On the day of your training flight, your instructor should conduct a thorough ground briefing with you on current conditions, the airports and runways to be used for the exercise, and the recommended final approach speed and flap setting for your airplane. Discuss the meaning and use of a slip and how to properly position the ailerons and rudder during the approach, landing and rollout.
Manage your airspeed, taking into consideration reported surface wind speed and direction. The FAA Airplane Flying Handbook recommends adding one-half the gust factor to your final approach speed. For example, if the normal approach speed in your airplane is 80 knots and you are attempting to land in a crosswind reported at 10 knots gusting to 20 knots, the "gust factor" is 10 knots, so you should plan your approach at 85 knots.
Always be prepared to execute a safe go-around anytime the landing doesn't feel right, especially if you lose directional control or the airplane "balloons" before touchdown. Practice balked landings on your own or with an instructor regularly.
You might also consider getting some experience flying a tailwheel airplane to master timely and correct rudder usage during a crosswind approach and landing.
Know your personal limitations, and stick with them. Recognize that a 10-knot direct crosswind might not be a big deal to an experienced pilot in a heavy airplane but might present significant challenges to a rusty pilot flying a light aircraft.
