I'm sorry, but I can't view images directly. However, I can help you understand how to interpret a weather map for your decision.
If the weather map indicates sunny and clear conditions in Corpus Christi, while showing rain, clouds, or storms in Galveston, then Corpus Christi would be the better choice for a beach visit. On the other hand, if both cities are experiencing similar weather conditions, look for any differences in temperature or wind patterns. Ultimately, choose the location with the warmer temperatures, less precipitation, and better overall conditions for a beach day. Please describe the map's key features, and I can provide more specific advice!
