Mars changes its distance from Earth substantially. It can be an obvious reddish point while still being too small in a telescope for useful surface detail. A familiar colour is a starting clue, not a complete identification.
Choose a useful moment
Confirm Mars against a dated chart and check its altitude during your actual observing window. A high target is generally a better starting point than one close to the horizon. Use the Moon and planets goal; bright moonlight does not carry a penalty for that assessment.
Begin at low magnification and increase only while focus and image steadiness remain useful. The cloud forecast does not predict atmospheric seeing, and the small sky diagram does not model the size of Mars's disc. Do not interpret a clear score as a promise of polar caps or surface markings.
Keep a sketch and record what is secure versus suspected. Compare attempts over several nights with similar equipment and conditions. For a close approach or opposition, use an up-to-date observing source to understand the apparent size and season rather than relying on a generic annual target list.
Check it from your location
A target's altitude and direction change with your location and time. Use a city session to see sampled positions. Deep-sky objects also need enough darkness and suitable optics; being above the horizon does not mean they will be visible.
