Dew and Monsoon Stargazing Playbook
In the humid tropics, “clear” often means wet glass by 01:00. Plan the dry window, not the whole night.
Stargazing Weather · Tonight Score
Dew
- High humidity plus falling temperature equals fogged lenses and eyepieces.
- Prefer earlier astronomical dark when dew risk rises after midnight.
- Bring lens cloths, a simple dew heater or hand warmer near optics, and a towel for seating.
- If Tonight score cites high dew, treat faint targets as optional even under low cloud.
Monsoon and convection
- Afternoon storms can clear into excellent evening transparency, or leave residual haze.
- Do not drive far on a Maybe score when radar shows training showers on your road.
- Keep a backup bright-target plan (Moon, planets, ISS) for partly cloudy gaps.
Decision loop
- Read dew and cloud on Stargazing Weather.
- Confirm Go / Maybe / Skip on Tonight Score.
- If Go or Maybe, take the overlapping dark window from Dark Sky Window.
- Pack dew mitigation before you leave.
